How Third Party Content Affects Website Performance
• Content view: Some webpages use Java applets for interactive content like online games. If the Java plug-in isn’t installed, then the browser won’t be able to run the applet and interactive content can’t load.
• Ads: Live ads in a web page that pull data from a third party site will cause performance issues in websites.
• Live content: Live third-party content like, game scores or a stock ticker, will constantly refresh the page with the latest updates. This can affect other page elements and slow their load times.

What does Windows® Logs tell you?
A Windows domain controller generates almost 100,000 event logs per hour, which means that the collective output from a rack full of Windows servers on an average day would more or less fill up the phone book of Austin. These event logs contain vital information such as logon failures, failed attempts to access secure files, and more. If your environment includes Windows servers and workstations, you need to make sure that you monitor Windows event logs across its multiple versions.
Why monitor Windows Event Logs?
It is important to determine the reliability issues in your network, to keep a tab on the various events that lead to security problems and downtime. Monitoring Windows event logs gives you critical information, for example:
1. Application logs contain events logged by applications.
2. Security logs contain records of valid and invalid logon attempts and events related to resources use, such as creating, opening, or deleting files or other objects.
3. System logs comprise system component events like driver failures and hardware issues.
4. DNS servers also store DNS events in their logs.
Windows event logs, typically gathers log data published by installed applications, services and system processes and places them into event log channels.
Why is Windows Event Viewer Not Enough?
Windows operating systems allow you to view the event logs on a local or a remote machine with the help of Windows Event Viewer, a built-in tool available within the OS. The issue with the Event Viewer is that it doesn't help you analyze the event in depth to the level of understanding the root cause. Also that the Event Viewer differs with the version of the Windows OS that you are using as it logs events with according to the version of OS.
It is very critical to analyze the event and understand the root cause. You need a log management solution that can efficiently monitor your Windows Event logs and alert you in real-time as your workstations encounter security threats and policy violations. Secondly, monitoring workstation logs in addition to server logs makes event analysis and user activity awareness even more comprehensive and actionable. To make log analysis more efficient, you need to collect and consolidate log data across the IT environment, and correlate events from multiple devices in real-time.
SolarWinds Log & Event Manager (LEM) completely monitors Windows Event logs across various versions of Windows servers and workstations. It acts as a central collection point for Windows system log data, automatically aggregating and then normalizing this data into a consistent format. LEM also performs multiple event correlation, including the distinct ability to set independent activity thresholds per event or per group to understand relationships between dramatically different activities. It lets you effectively identify and respond to threats in real time, rather than being reactive.

What is VM Sprawl?
Virtual machine (VM) sprawl is the uncontrolled growth and proliferation of VMs in a virtual environment. When this happens, the network reaches the point where you can't manage the VMs effectively and they start demanding excessive host resources. Typically, VM sprawl occurs as the result of the creation of virtual machines that stay unused or forgotten but still consuming host resources. You don’t realize it immediately after virtualizing your servers. VM sprawl happens over time and if it remains unchecked, say, at the end of one year, you’ll be surprised to see the number of VMs associated with the same number of hosts you created initially.
This is not good because VM sprawl can waste resources and contribute to resource contention on actively used VMs. It doesn’t end here. You’ll need to feed your new VMs more resources and you will likely end up looking for more procurement budget – which is definitely NOT what you want!
How to Identify VM Sprawl?
VM sprawl has no clearly defined symptoms, but there are some typical characteristics that can help you identify it.
#1 Look for Idle/Stale VMs
Idle or stale VMs are those VMs that are existing in your virtual environment consuming host CPU, memory, disk, and network resources but not actively used.
Stale VMs can also show other indicators such as:
Also, look for the VM creation date to ascertain how long the VM has been existing and how little it has been actively used.
#2 Identify VMs with Old and Large Snapshots
A VM snapshot is a copy of the virtual machine disk file that preserves the disk file system and memory of the VM, and enables you to revert to the snapshot as a rollback or disaster recovery mechanism. While snapshots can be real lifesavers when upgrading or patching applications and servers, they also consume a lot of disk storage and even end up choking the performance of the VM. This is a typical problem caused by VM sprawl.
Look for VMs with old snapshots, large snapshots and also a large number of snapshots. Identify which are the snapshots are really required for business continuity and delete the rest to reclaim storage space for your VMs.
#3 Discover Orphaned VMs
An orphaned virtual machine is one that was created initially but, over time, has lost its association with its host. A VMs also shows as orphaned if it exists on a different host than the one expected by the hypervisor. This is a cause of VM sprawl as these VMs have been allocated resources in the past, but you do not have the visibility into which host is linked to them. Orphaned VMs are not really idle. The consume memory and CPU cycles, disk capacity, and add complexity to data protection.
#4 Monitor Oversized and Undersized VMs
An oversized VM is one that consistently uses less capacity than its configured capacity. Oversizing a VM you can result in decreased performance of other VMs inside the cluster. Conversely, an undersized VM is one that runs more load than what its configured resources can support. This can hurt VM performance and cause VM resource hogging that causes contention with other VMs in the cluster. You need to constantly look for the statistics of oversized and undersized VMs in your virtual environment and right-size the VMs by reclaiming and providing resources where they are needed most.
These are only some indicators to identify VM sprawl. To keep VM sprawl at bay you need to get visibility into the resource allocation and utilization of the hosts and VMs constantly and monitor VM performance metrics over time to understand the growth trend of VMs being added.
Some Tips to Keep VM Sprawl Under Control

Patch management has become so critical in the IT landscape that it’s now a must-have security solution in enterprises. When you utilize effective patch management, you’ll be able to eliminate application vulnerabilities and the security threats that arise from them. Today, IT admins are looking for ways to make software patching more efficient and error free. This can be achieved by implementing centralized and automated solutions. Let’s take a look at some of the key benefits of automating patch management.
#1 Enhance Endpoint Security
Automating patch management allows you to be more efficient because it allows you to instantly and uniformly patch all the systems in your IT infrastructure. With this approach, you’ll be able to schedule timely patch deployments to multiple systems at the same time and keep them protected against critical vulnerabilities. You can schedule automated patch deployment to all your vulnerable systems as soon as a security update, bug fix, or a newer application version is released. In addition, patch management automation allows you to:
Timely updates of security patches will reduce the risk of exposing systems to attacks like security breaches, and data loss.
#2 Eliminate Manual Errors
When you combine the diverse nature of the IT infrastructure and the application portfolio, complexity of system configurations, and all the various enterprise policies and procedures, it's clear to see that there's a good chance a manual software patching approach will result in errors.
Manual software patch errors can occur because of:
When you implement an automated approach to patch management, you can rest assured that all these manual errors can be avoided. You’ll also be able to schedule updates based on whichever systems you want to update, whichever patches you want updates to, and at whichever time of the day, week, or month you want the patch to occur.
#3 Improve IT Productivity
Patch management is a tedious process. You have to manually analyze, prepare, test and deploy software updates to the required endpoint nodes. It’s exhausting to even think about. This obviously consumes a lot a time and effort for IT admins.
Automated patch management simplifies a ton of steps in the enterprise patch management process—from research, to scheduling, deployment, and reporting—saving you hours of time and effort. In addition to productivity, automated patching also frees up technical resources for other mission-critical IT tasks.
#4 Simplify Compliance Reporting
Automating patch management also means automating and scheduling patch reporting to notify patch status before and after each patch deployment. Patch reports are key resources to support compliance and IT audits. Automating compliance reporting will help you get:

Are your Microsoft Servers running slow? Read this post for best practices on the top metrics to monitor.
• When experiencing an application or server performance issue in your environment, perhaps the most obvious metric you’re likely to look to first is the affected servers CPU utilization. This metric provides insight into how much load is being placed on the servers’ processor at any given time. A high and sustained CPU utilization may be indicative of underperforming hardware that may need replacement or upgrade. If the server is virtual it may suggest that the virtual machine suffers from insufficient resource allocation. If the machine provides multiple services and functions, you may also want to consider distributing those roles amongst other servers in your environment to distribute the load more evenly.
• Another likely culprit of poorly performing applications and sluggish servers is the machines physical memory consumption. RAM is where the operating system stores information it’s actively using to service actively running applications running on the host. When a server has an inadequate amount of memory to run both the operating system and the applications that run on it, the OS will begin moving lesser used blocks of memory temporarily to virtual memory located on disk. This commonly referred to as paging. As demand for memory resources increase the more paging occurs. Because the disks are significantly slower than RAM this introduces a bottleneck on the server that can significantly impact overall server performance. Should this condition occur for a prolonged period of time you should consider adding additional RAM to the physical or virtual server.
• As virtual memory consumption increases hundreds of megabytes of information are constantly moving from RAM to disk and back to RAM again. This puts tremendous strain on the physical disks where the swap file is located. It’s always best to ensure your operating systems swap file is located on a different drive than the operating system to prevent swap file fragmentation and to ensure paging doesn’t impact other disk I/O intensive operations such as databases.
• Disk performance is the actually the leading cause of server and application performance issues today. Big data and virtualization have only compounded this problem by placing ever increasing additional strain on servers’ disk I/O subsystems. As such, it’s important to keep close tabs on your server’s queued I/O and disk latency to understand how your storage performance is impacting your applications. When either disk latency exceeds 100ms for any period of time this is likely indicative of a storage performance issue. The same can be said of sustained high disk Queue length. If your server is suffering from poor storage I/O performance consider changing your RAID type, adding more physical disks to your array, upgrading your storage controller to one with larger cache, or replacing older, slower disks with solid state or 15k SAS drives. Alternatively you may be able to more evenly distribute your applications disk I/O load by moving databases, applications, temp files, etc. across multiple disks.
• Finally, server monitoring should include keeping an eye on the hardware of your Windows servers. If there is an underlying problem with the hardware, the application may not function correctly, and an unforeseen hardware failure (hard drive, fan, etc.) can take your application down without any warning.

Upgrading from LEM 5.5 to 5.6 performs a database migration of your data. Performing this upgrade converts your existing information, from newest to oldest, into the database format. In our latest release of LEM, we are migrating from a third party database software to an in-house database.
We have included a banner that displays the status of the migration and the estimated time until it is complete.
Depending on the amount of data to be migrated and the system load, the migration could take from hours up to a few weeks. Data is migrated from newest to oldest.
No, the data is transferred over completely. New data continues to be migrated as it comes in and old data is moved over when new data is not being transferred.
Are you champing at the bit while waiting for SAM 6.0 to be released? I don't blame you. I am too and for a different reason. Suffice to say, this release will be a beast! It is the musical equivalent of Liszt's Hungarian Rhapsody No. 2. What does this mean for you? Well, I can't give away all the secrets, but I liken the new features and views they provide to the cockpit of the space shuttle. Ridiculous!
So, what can I tell you? Not much; however, you can get a sneak peak of some of the new features here.
In SAM 5.0, we introduced the the Real Time Process Explorer. In 5.5 we took it a step further with the Service Control Manager. Now, in SAM 6.OMG, we are offering the Real Time Event Viewer - and it's just where you'd expect to find it!
Here's a better view, just to tease you a little more:
This, my friends, is cool. But it pales in comparison to the other really, really, really cool features I can't mention! Why do you think I'm calling it SAM 6.OMG? Because it's bigger, better, and cooler than anything else we've ever done - and we're all working ourselves to the breaking point, but we love it!
If you’re lucky, you can identify the problem and troubleshoot right away. If you don’t yet know what you’re dealing with, you could start here:
• Server performance: Momentary server hiccups may result in incomplete code being sent to the browser.
• Corrupt cache file: This can cause unstable application performance and random error messages that pop up in the browser. Sometimes it can even make the application crash.
• Others possible issues: The scripting engine, video card drivers, or Direct X controls could be corrupt or outdated.
3. Monitor load times. Establish an ideal baseline for how long it should take for your application to load. Then monitor the load times of each step in the page. If a step loads slowly, you’ll then receive an alert about the problem in the page or step.
Monitor individual page elements to identify what is causing the issue
• Intuitive charts to monitor page elements, their load speeds & timings
• A graphical dashboard that monitors every component of your site
• Drill-down capabilities & isolation of performance issues to quickly determine what’s causing the delay
• Customized alerts based on the severity level
All of us are aware of the Java® 7 update 21 that plugs 42 security holes, aren’t we? Oracle® issues update for Java to fix security issues, root certificate changes, algorithm changes, and code level bug problems every four months, and provides a collection of critical patch updates and non-security fixes.
With Java Update 21, Oracle shares that 39 of the 42 vulnerabilities for which the patches are rolled out, are remotely exploitable without authentication. Also, in addition to the security fixes, the new update will also make changes to the way Java applets are handled and presented in Web browsers that have the Java plug-in enabled.
Here’s the thing that is alarming: Despite the growing awareness of the vulnerabilities, only 7% percent of the users are running the latest version. Some scary factoids based on a report by WebSense:
The more you fail to keep up with security updates from your software vendors, the more you are prone to vulnerability. Alright, so how do you keep up with the patches? Given the complexity and dynamism of exploit kits and their updates, you need a patching strategy!
Patching Java can be tricky at times. For example, when you apply a patch, Java may uninstall the older version. Hence, you need to ensure that your patch management strategy allows you to create advanced before and after patch deployment scenarios.
Now patch Java updates with ease!!
With SolarWinds Patch Manager, you can easily discover systems that are not running the latest Java updates and patch them pronto. Patch Manager allows you to deploy pre-tested Java updates to any number of workstations, servers and VMs you need to update. Once you deploy the update, you can run reports to check how successful your patching was. You can also customize patch reports, schedule, and email them.
Patch Manager reduces weeks of your patching efforts and helps you protect software and applications against vulnerabilities. Java patch management made simpler, easier and effective!
Are you feeling the pain of an increasingly dynamic and growing network? Are you frustrated with tracing cables to track down a problem device? Are you having trouble justifying the purchase of another switch?
Why not use a tool that can do all the hard work for you?
1. Switch Port Utilization and Capacity Planning
Mapping switches and monitoring the status of ports provides crucial visibility to optimize switch port utilization and also to accommodate IP subnet capacity planning. At hand information helps network admins foresee the number of switches required to support a full subnet and more efficiently scale the network. Additionally, admins can obtain the necessary data to determine the number of subnets required to attain maximum switch port utilization.
Real-time switch port mapping and monitoring provides vital information, including:
2. Tracking and Troubleshooting
Knowing the exact location to allow/stop a user/device from the network is a simple, but very valuable piece of information. Unfortunately, it can be very difficult and time-consuming to manually trace a cable to a device.
Network admins can improve issue troubleshooting and network access protection by gaining visibility into both current and historical endpoint connection details, including IP address, MAC address, VLAN, switch name, and port information. Equipped with this information, admins are better equipped to quickly locate offending devices and suspicious activity associated with an IP address to resolve network issues fast.
How can SolarWinds help?
SolarWinds IP Address Manager (IPAM) integrates with User Device Tracker (UDT) to provide automated IP address management, powerful switch port monitoring, and integrated endpoint tracking. This built-in integration provides end-to-end mapping of an IP address to connected user/device, enabling network admins to view IP address information right alongside device port and connection details in the same window.
With IPAM + UDT, you can:
Make life easier! Download the IP Control Bundle to track and trace Your IP Address Footprints up to the port and user level. The physical location of the switch does not matter - everything is administered from a single web console!
If, for any significant length of time, you have been using SolarWinds NPM for network management or SolarWinds SAM for application and server management, you have probably heard of an additional polling engine. Maybe you're even currently using or considering using an additional polling engine to spread your management load or expand your monitoring capacity. Excellent. That's exactly what additional polling engines were designed to do for you.
In this blog post, however, I'd like to introduce a couple of lesser-known things those amazing Additional Polling Engines can do for SolarWinds NPM, specifically: remote polling and poller stacking.
SolarWinds NPM version 10.4 introduced remote polling for Additional Polling Engines. Poller remotability allows you to continue polling and storing data, even when your remote additional polling engine is no longer connected to the SolarWinds database. In previous versions, if your additional polling engine lost its connection to the SolarWinds database, even for a short period of time, you would see data gaps for the devices monitored by the disconnected polling engine. Now, additional polling engines can use Microsoft Message Queuing (MSMQ) to temporarily store polled data locally, on the server hosting the additional polling engine, and then later store it when the database connection is restored.
If your hardware can handle it, with the latest version of SolarWinds NPM, you can now install up to three unique polling engines on a single server, sharing a single IP address. Stackable polling engines enable you to effectively triple the polling capacity of a single server.
The attached document provides guidelines for these extended additional polling engine features. Currently, stackable and remote polling engines are only available to a limited number of SolarWinds products, but availability should expand in the future.
One of the scenarios sometimes encountered in patch management environments is the disconnected network. Microsoft recognized this need and created functionality in WSUS to handle disconnected networks, and I wrote about this in the PatchZone article: Considerations with the WSUS Disconnected Network Environment.
Just to review, a disconnected network scenario with WSUS and Patch Manager looks like this:
One of each server (WSUS, Patch Manager) in each network.
Patch Manager also provides a similar capability as WSUS, but with a couple of nice enhancements. First, where WSUS requires you to export all of the updates in the catalog, Patch Manager allows you to export one, some, or all of the updates. Second, WSUS requires you to export the metadata separately from the installation files; Patch Manager allows you to bundle them in the same CAB file for transport on removable media. Detailed procedures can be found in the Patch Manager Administrator Guide, in the section “Importing and Exporting Catalog” on page 52.
However, the biggest challenge for Patch Manager in this scenario is not a technological problem, but rather a licensing problem. There’s no argument that a 250-node license for a two client installation of Patch Manager on the connected network is a pretty steep price to pay. If you were willing to forego telephone support for that connected server, you could use a 50-node installation of DameWare Patch Manager, but even that’s a pricey cost for a two-node network.
The good news, however, is that you do not have to purchase a separate license for your single-node connected network. With a bit of creative use of Patch Manager server roles, you can license that connected server as a node of the license applied to the disconnected server. Let’s look at how this is done.
On the disconnected network, we’re going to install the Patch Manager Primary Application Server (PAS). This is the server that will be used to manage the WSUS server in the disconnected network, as well as the clients of the disconnected network.
Also, on the disconnected network, we’re going to install a Patch Manager Secondary Application Server (SAS) with the Management Server role. This server will be registered with the PAS, and as such, will be automatically licensed for use by the license applied to the PAS. Note that this can be either a physical system or a virtual machine. When we’re ready to put this SAS in service, it’s just a matter of transporting the physical system (or virtual machine files) across the network gap and plugging it into the connected network.
There is one technological consideration to be aware of in this scenario. The PAS replicates all defined scope objects (Domains, Workgroups, WSUS Servers, and Computers) to the SAS. In order to get the connected WSUS server registered on the SAS, the WSUS server scope object must be created at the PAS and replicated before moving the SAS to the connected network.
From the Patch Manager System Configuration node, in the Details Pane, double-click on Scope Management. Click on Add Rule, and select Update Services Server. Use the “Enter the object to add” button to manually create an entry for the connected WSUS server, and click on Save. In a couple of minutes, that scope declaration will replicate to the SAS. You can access the Scope Management tool on the SAS to confirm. You may also wish to add the Domain or Workgroup for the connected network.
One the replication is completed and the SAS moved to the connected network, the connected WSUS server can be registered on the SAS and added to the management group defined on the SAS.
Credentials, Credential Rings, Security Role memberships, and User Preferences are all entities defined at each individual application server, so you can create those directly on the SAS at any time, before or after actual deployment to the connected network.

Workstation monitoring is a crucial aspect of comprehensive network security that is sometimes overlooked. Threats to your workstations come in a variety of forms and can open the possibility of a breach or intrusion into your corporate network. Some common
threats to workstation security include your setup being exploited, credentials being stolen, unauthorized access being gained, and confidential data being stolen via USBs and other mass storage devices. These are just a few of the many impending threats faced by security teams that can upset important IT security policies and regulations.
With its many built-in Active Responses, SolarWinds Log & Event Manager (LEM) can help combat critical workstation security threats lurking in your network. LEM's Active Responses are automated and programmed to react in real time and counter anomalies, threats, and policy violations—all without requiring human intervention to confirm or activate any action.
Let’s discuss some useful Active Responses that LEM offers out of the box for workstation security and management.
#1 Kill Suspicious and Unapproved Processes
There are instances when unknown applications and processes are running on the background on your enterprise workstations. While some of these may be harmless, there are other rogue processes that are potentially dangerous and can infect your terminals. You need to be alerted in real time when such suspicious and unauthorized processes are running on the endpoints, and be able to automatically kill them.
LEM Active Response: The Kill Process Active Response enables LEM to automatically kill a suspicious or unapproved process by name or ID. According to the value in the ProcessID field of the corresponding LEM alert, LEM kills the process:
#2 Disable Networking on Infected Workstation
Once a workstation is infected, it’s highly possible that the infection will spread and affect other systems on the network. The wise security action would be to disable networking on the infected workstation from the network at the NIC card level. This helps quarantine the offending workstation and isolate it from the network.
LEM Active Response: Use the Disable Networking Active Response to disable networking on a workstation at the Windows® Device Manager level. This action is useful for isolating network infections and attacks, and can be automated in an LEM rule, or executed manually from the Respond menu in the LEM Console.
#3 Remove Unapproved Users from Administrative Group
As the IT administrator, you need to ensure only approved users are part of the Local Admins administrative group. If any ill-intentioned employees or unapproved users gain access, you should be able to remove them from the administrative group or AD. Based on where the unapproved user is identified, whether at the domain level or at the local level, you should be able to remove the user automatically.
LEM Active Response: LEM uses a Windows Active Response tool based on where you want to remove the user(s) from—the domain level or local level. This tool configures an actor that enables Windows Active Response capabilities on LEM Agents deployed Windows operating systems.
#4 Detach Unauthorized USB Device
Intentional or unintentional loss of sensitive information from enterprise workstation endpoints is a grave threat that security practitioners must address. USB devices can be used to steal corporate data and introduce malware or spyware into the workstation. Whenever unauthorized USB access is detected on the network, the USB device should be automatically disabled from the workstation. Some common use cases of dangerous USB activity on the network are:
LEM Active Response: The Detach USB Device Active Response allows you to automatically detach a USB or mass storage device from a workstation. This action is useful for allowing only specific devices to be attached to your Windows computers or detaching any device exhibiting suspicious behavior.
SolarWinds Log & Event Manager can additionally detect unexpected or inappropriate network activity, identify isolated spikes in network traffic, proxy, or file activity, and send a popup to the workstation notifying the user that’s been spotted. In addition, there are multiple other built-in computer-based and user-based Active Responses available in LEM that will help you protect your workstations from user misbehavior or policy violation.
Leverage the new LEM Workstation Edition for more scalable workstation log management.
Welcome to SolarWinds blog series “Diving Deeper with NetFlow – Tips and Tricks”. This is the fifth part of the six part series where you can learn new tips by understanding more about NetFlow and some use cases for effective network monitoring.
In the previous blog, we had discussed monitoring BYOD, its implications on your network, and how NetFlow helps breakdown BYOD bandwidth usage by monitoring what kind of applications are being used. In this blog, we will dive into Quality of Service (QoS) to understand how you can implement QoS polices across your network by analyzing the data from NetFlow.
In today’s advanced network environment, controlling and validating network traffic has become more challenging due to unwanted applications installed on BYOD devices. Rogue applications can block network bandwidth resulting in an interruption of important business applications. It is vital to define Quality of Service (QoS) and set priorities for various applications. As an example, 50% of your bandwidth can be set to VoIP applications which are business sensitive while other non-critical applications are allocated lower bandwidth. Thus, by defining QoS classes and assigning policies, network administrators can set predefined actions to be triggered under specific cases.
Applications will compete with each other for bandwidth when traversing the WAN and since bandwidth is neither infinite nor free, it only makes sense that you will want to see how your bandwidth is being used. Since NetFlow data reports on Type of Service (ToS) and DSCP fields from traffic conversations you can monitor your bandwidth usage by application and measure the effectiveness of your QoS policies.
Using NetFlow Traffic Analyzer, you can view network traffic segmented by Class of Service methods, such as Type of Service or DSCP ensuring that critical traffic such as voice or video is prioritized and isn’t dropped.
To learn more about NetFlow, check out our NetFlow V9 Datagram Knowledge Series.

What are “Rules” in Log & Event Manager?
Rules, in SolarWinds Log & Event Manager (LEM), are customizable event correlation algorithms that correlate events sent by LEM Agents and remote logging devices. Whether you are monitoring the LEM console or not, LEM rules track events in real time allowing you to
When a single event or a series of events meet a rule's correlation conditions, the rule automatically prompts the LEM Manager to take action, such as notifying the appropriate users, or performing an active response (blocking the IP address or stopping a particular process). LEM rules offer the ability to use simple and advanced thresholds such as time/frequency and same/distinct to add complexity and significantly reduce false positives.
Correlation Rule Builder
SolarWinds LEM has a built-in Rule Builder that employs an intuitive graphical interface with easy-to-use techniques such as drag and drop options, an icon-based tool panel, and a graphical object selection panel to:
The rule builder interface incorporates familiar easy-to-use techniques such as drag and drop, an icon-based tool panel, and a graphical object selection panel. To further help rule creation, there are additional events and fields on the left-side of the rule builder window that you can to add to the correlation rule. The rule builder uses a logical ‘AND’ or ‘OR’ Boolean logic for rule creation.
In addition to the ease with which new rules can be created, SolarWinds LEM offers more than 700 pre-built correlation rules that cover critical network infrastructure, change management and network security functions.
Rule Categories & Tags (New in version 5.6)
LEM rules are organized into pre-built categories to better pinpoint use cases like security, IT operations, compliance and change management. There are also sub-categories under each of the categories these to display rules for specific uses.
SolarWinds LEM also allows you to add tags to categorize a rule to make rule search easier. Tagging the rule will associate it with existing rule categories or you can also create a custom categories for new rule that will be displayed the Rule Categories menu. The rules “tagging” feature makes it much easier to pinpoint rules that meet specific needs like compliance, security etc.
Download SolarWinds Log & Event Manager today and easily build correlation rules to alert on and respond to security events happening in your network and enhance IT security.
Watch this short video to learn how to easily create and customize correlation rules using SolarWinds LEM.

Getting past practical hurdles and taking control of your entire IP infrastructure calls for a few specific essentials. What are they, and how do you use them to ensure network availability and performance.
Let’s review the key elements in IP infrastructure management, associated best practices and solutions.
IP Space Management
A network admin on a daily basis deals with management tasks like - Address planning, Address allocation, Centralized inventory, Real-time IP status and IPv6 planning.
If you are still using spreadsheets, note that they require a lot of manual entry and verification, are prone to human errors, and are difficult to control especially with multiple people accessing it.
To be able to successfully meet user and network requirements,
DHCP and DNS Server Management
Individually managing both DHCP and DNS servers is an effort, especially in networks operating with multiple vendors. Therefore, to minimize human errors and manual processes, choose a solution that interacts with both your DHCP and DNS servers. Increase efficiency with,
Simplify Management with an IP Address Manager (IPAM)
Deploy an IPAM tool that’s easy to install, supports multi-vendor DHCP & DNS management, and simplifies troubleshooting with real-time alerting and reporting. Some of the things you’d want on your checklist for a good IPAM are:
Go ahead and automate your IP address management tasks to save time, reduce errors & increase efficiency. SolarWinds IP Address Manager (IPAM) offers what you need to take control of your IP Infrastructure Management. Download a trial version today!
The National Security Administration (NSA) has been in the headlines recently; something I’m sure every top-secret intelligence agency longs for. In the myriad articles, interviews, and stories about how much data the NSA “gathers” about e-mail contents, phone calls, mobile phone tracking, text messages, and what you feed your cat, you might recall mention of a new NSA facility under construction in Utah. In case you missed this tidbit, just Google “NSA Utah” for a return of a little over 57 million hits.
The big story, for me at least, is not that our government is building a new super-snooper facility in the middle of nowhere, (Apologies to Mormons and other residents of the state.) but the quantity of data the installation is projected to handle.
When I heard the term “zettabyte” in reference to the new agency outlet, just like you, I scrambled for my browser to find out just how many a zetta is. According to Wikipedia, a zettabyte is “The zettabyte is a multiple of the unit byte for digital information. The prefix zetta indicates the seventh power of 1000 and means 1021 in the International System of Units (SI), and therefore one zettabyte is one sextillion (one long scale trilliard) bytes.” (See http://en.wikipedia.org/wiki/Zettabyte. The Wikipedia entry is worth a read.) The new NSA post is estimated to support 5 zettabytes of storage capacity. For the less mathematically astute of us, myself included, in Texas that’s what we call a !@#$load.
Let’s dial that zettabyte into perspective: If the earth is ~197 million square miles in surface area (it is), and each square mile is the equivalent of 1 zettabyte, I am in possession of empirical knowledge that my calculator does not produce enough zeroes to show me how many times a zetta of square miles would cover the earth. With excessive confidence, I can now say that a zettabyte should be enough for anyone.
We had an awesome week in the SolarWinds booth at TechEd North America. It's great being able to meet and chat with our customers, and we were particularly surprised at the number of SolarWinds customers attending TechEd NA this year. We talked about all the products, but especially a lot about SAM and Patch Manager, and Virtualization Manager was a finalist for the Best of TechEd Awards. We even closed a couple of support tickets in the booth!
Perhaps the most notable announcement to come out of TechEd was the forthcoming release of Windows Server 2012 R2 (aka Windows 8.1) and System Center 2012 R2. Preview bits are expected to be available by the end of June, and you can register for notification from Microsoft when the bits are available.
But, no doubt, the high point of the week (well, at least for me, being the party animal that I am ... well, Used To Be!), was the closing party. Two things to catch your attention from this event, first a memorable performance of Proud Mary by Tina Turner and the [TechEd] Tinettes... here's a (not very good) photo I captured to commemorate the occasion. At the end, to a one, each of those dozen IT pros got/gave hugs from/to Tina. I'm not sure who was more excited... the guys being in the presence of music royalty, or Tina having a dozen men half her age (or more) huggin' on her. One thing's for sure ... the lady can still dance, sing, and rock a house.
I'm already getting warmed up for TechEd North America 2014... which will be held in my favorite city ... Houston! May 12-15, 2014.
In an earlier blog, we discussed how important it is to monitor logs from workstations. To address this much demanded security use case, SolarWinds introduced Log & Event Manager Workstation Edition with the release of LEM 5.6.
What is Log & Event Manager Workstation Edition?
LEM Workstation Edition is a special licensing model of Log & Event Manager that accommodates log management for thousands of workstation nodes at a much competitive and affordable pricing. LEM Workstation Edition provides all the functionality of LEM (including Active Responses, USB defender, Compliance Reports, etc.) to help you collect, correlate, analyze and store logs from more number of workstation nodes. This licensing model will greatly benefit LEM users for you can now pay less for monitoring more workstation nodes when compared to non-workstation nodes.
Workstation Edition nodes are priced at a much affordable pricing than the normal LEM nodes (which are now called ‘Universal’ nodes). The screenshot below shows how the Workstation and Universal nodes are differentiated on the LEM console (Manage Nodes section).
With this release, LEM 5.6,

Welcome to SolarWinds blog series “Diving Deeper with NetFlow – Tips and Tricks”. This is the fourth part of the 6 part series where you can learn new tips by understanding more about NetFlow and some use cases for effective network monitoring.
In the previous blog, we had discussed the impact of cloud applications on enterprise network and how you can track your cloud performance while effectively monitoring your network. In this blog we will look into monitoring the BYOD impact on your network and its implications.
In order to increase productivity, many organizations today encourage the usage of BYOD and telecommuting. With that network administrators have added another burden to the list of problems that they already face. With an increase in personal devices, businesses of all sizes are trying to solve the bandwidth problems caused by BYOD.
Managing BYOD without concrete policies can create significant issues for network administrators. Some of these are:
How NetFlow helps to monitor BYOD?
BYOD is going to add more traffic to your network and understanding the impact on the network’s bandwidth is imperative. Blocking unauthorized applications from hogging your network bandwidth is essential to having more optimal network usage as these unknown applications compete with business applications.
NetFlow helps breakdown the BYOD bandwidth usage by monitoring what kind of applications are being used, and what the sources and destinations of the increased traffic are. In depth tracking using NetFlow provides real-time information on network traffic and BYOD monitoring begins at the access layer, closer to the traffic source. By analyzing the data from NetFlow, you can implement QoS policies across the network.
Using NetFlow Traffic Analyzer, you can monitor the bandwidth consumed by personal devices and easily define policies to streamline the network traffic. Network administrators can find bottlenecks in network bandwidth by analyzing the source and destination of the traffic, and deploy policy restrictions on those devices.
To learn more about NetFlow, check out our NetFlow V9 Datagram Knowledge Series.
Watch the entire ‘Diving Deeper with NetFlow – Tips and Tricks’ webcast here and become an expert in understanding and implementing NetFlow in your enterprise networks.

A Primary Rate Interface (PRI) is not an esoteric banking term designed to take as much money as possible away from your account. It's a less obscure telecom term that connects your internal PBX to "the outside."
The PRI is the part of the ISDN that is responsible for carrying voice and data from point A to point B. This is essentially the trunk you rent from your telecom provider to connect your internal VoIP lines to the external PSTN. (I wrote a blog about trunks a while back, if you're interested.)
A PRI uses different carrier lines depending on which part of the world you live in. For example, if you live in North America, the PRI uses a T1 line. If you live in Europe, it uses an E1 line. These carriers establish how many external phone lines you can access and how much data you can transmit.
Using the T1 line as an example, there are 24 available channels. These channels are further divided into B channels and D channels. The B channels carry your voice and data, . The D channels carry control and signaling information. A single T1 PRI line has 23 B channels and 1 D channel. If you use more than one PRI line, you can often reduce the total number of D channels. If you lease two PRI lines, you could have 27 B channels and a single D channel, giving you 27 outside telephone lines instead of 26 outside lines.
A quick Bing search of German websites reveals a number of heavyweight secure file transfer options that require consulting services for deployment. Our take? Perhaps Germany's system administrators need something faster and easier.
Two of the first entries you will see on a German search for "secure file transfer" are heavyweight offerings from SEEBURGER and Envision Software.
SEEBURGER is a business integration and EDI company offering software for managed file transfer. However, you can't just download and try the software for yourself without first talking to someone; their model requires you (or preferably, your boss) to hear about the many pieces of your business that need to be interconnected, even though you just want to put up a secure file transfer server and go home.
Envision Software doesn't actually make software. Instead, they are a consulting operation that deploys IBM solutions (perhaps from IBM's Sterling Commerce acquisition) and Proginet EDI-based solutions. Suffice it to say, none of that software can be downloaded immediately either.
And even if you could download something from these two companies, purchasing it with your credit card may not be possible. These are enterprise software solutions...with enterprise software price tags.
The recent trend in Germany, the UK and elsewhere in the EU has been for "enterprise" managed file transfer solutions to be replaced with less expensive secure file transfer solutions, such as SolarWinds Serv-U MFT Server, that are easier to deploy, easier to maintain, and easier for partners and employees to use.
Secure file transfer software is easier to deploy because it can be downloaded and installed from publicly available websites at any time. Software trials are automatically activated and the products can normally be configured and started in less than ten minutes. Even add-on components such as a secure DMZ Gateway can be deployed without a consultant or calls to the company’s support desk.
Secure file transfer options are easier to maintain because they can be plugged into existing Active Directory domains to provide authentication services and account information; this avoids hours of user maintenance. Secure file transfer software may also take advantage of existing home folders, Windows shares and other enterprise storage, where other managed file transfer systems based on EDI technology practically require a hermetically sealed environment just to function.
Finally, secure file transfer products are easier for employees and partners to use. They usually feature built-in web interfaces that allow people to securely upload and download files without requiring them to get an FTP client. They may also allow for remote Web administration, provide tailored mobile interfaces, and send email so that even a novice user can by notified when files are uploaded, downloaded, or deleted.
Yet another reason for the expansion of secure file transfer software is their growing support for the native language of their end-users. SolarWinds Serv-U servers have native German interfaces, and support for languages is granular enough to provide different languages for different users. To see how this works, download the FTP server today and select "German" when the installation prompts you for the desired language.
If you need secure file transfer software that avoids the hassle of "enterprise" sale cycles, deploys quickly and understands your language, consider Serv-U. See how easy and affordable secure file transfer can be by downloading your free 30-day FTP server evaluation today.
In my last post, we discussed uncovering issues with CSS. Let’s look at another aspect of website performance, HTML, to understand the causes of HTML performance issues, as well as how to identify them.
There are a few signs you should watch out for when your HTML page loads:
• How quickly your page responds to requests
• Whether the page elements are loading slowly
• Whether pages simply are not loading at all
Whatever the cause, website performance problems are worth looking into before your users are affected and you start getting trouble tickets.
What are Some Common HTML Issues?
• HTML Requests: Many times, HTML requests can take longer than usual to process, causing websites to load slowly. This can happen if there are poorly written queries, or if the server does not have enough physical or virtual memory.
• Non-compliant HTML Tags: If there are HTML typos or in cases of non-compliant HTML tags, the webpage would be displayed with errors.
• Missing Links to Files & Images: In many cases, files and images are uploaded but not linked in HTML. As a result, they do not get displayed in the website.
How to Detect an HTML Issue Before End-Users Call the Help Desk
Monitor page element load speeds and receive alerts when they exceed normal rates.
Identify which element is causing the issueusing the waterfall chart
Monitor images and file load times
To proactively monitor for issues involving non-compliant HTML tags and missing files/images, you can use image matching. Image match monitoring defines the number of seconds it takes for an image to load. Monitoring this will tell you if the image is loaded within the specified time. Then you know if the transaction passed or failed. You can also use this capability to validate if the image is displayed as intended.
Image match highlighted in yellow will allow you to edit load times for images in your HTML page.
Manage queries and HTML requests
Monitoring response times for SQL queries will show if the query is taking a longer time to process. You should also monitor if your servers have enough memory to handle the site load. Most server monitoring software can be used to monitor issues related to server memory.
Website Monitoring Simplified
SolarWinds Web Performance Monitor will ensure your HTML pages (and other front-end applications) will not affect your website performance, by letting you:
• Proactively monitor internal (behind the firewall), external (customer-facing) & cloud-based web applications
• Monitor HTML applications & its elements – images, scripts, etc. & their load speeds
• Record, replay & edit each step of a Web transaction
• Monitor HTML performances for multiple locations to ensure there is no drop in performance
• Enjoy a user-friendly graphical interface that monitors all components of your website
I encourage you to try a fully-functional 30-day free trial of SolarWinds Web Performance Monitor to experience it for yourself in your own environment.
BIND is the most widely used DNS software on the Internet. From a performance perspective, it’s quite powerful; from a management perspective, it can be quite cumbersome, especially if you’re not proficient with the command line interface.
As many network admins who manage BIND servers on a daily basis would agree, executing manual DNS updates through the CLI can be both tedious and error-prone. Fortunately, these admins now have another option—SolarWinds IP Address Manager (IPAM).
IPAM provides the flexibility of a user-friendly GUI to easily perform add/edit/delete functions for BIND DNS zones and records, thereby, eliminating the struggles of having to use the CLI.
With IPAM, you can manage and monitor not only your BIND DNS servers, but also Microsoft DHCP and DNS, as well as Cisco DHCP and ASA devices—all from a single, consolidated web interface!
Check out this video to learn more about IPAM’s new BIND DNS support.
To learn more, read our Tech Tips on - How to BIND with IPAM.
SolarWinds is happy to announce the release of DameWare Remote Support (DRS) version 10! Just like earlier versions, DRS v10 includes a comprehensive suite of systems administration tools, but this latest offering includes an innovative new mobile remote desktop application for iPhone and iPad that lets IT pros support end-users from anywhere using DameWare’s proprietary remote control protocol.
What is DameWare Mobile?
DameWare Mobile is an ideal tool for on-call rotations and after hours support. With it, sys admins can create mobile desktop remote control sessions from anywhere a 3G or 4G signal is available. It consists of two components: the DameWare Mobile Gateway Service and the DameWare Mobile Client.
The Mobile Gateway Service
The Mobile Gateway Service manages connections from the outside world to computers behind a firewall. It is packaged with the DRS installer and must be configured before users can connect to computers on a network from an iOS device. Generally speaking, there are two ways to configure the Gateway Service: on a Windows server residing in a DMZ or on a Windows server accessible through VPN connections. The setup is quick and painless as the installer for the Gateway Service is packaged with the DRS v10 installer.
The Mobile Client for iOS
The mobile client is available in the iTunes App store for iPads and iPhones running iOS 6 or higher. From the mobile client, users can connect to Windows computers with the DameWare agent on their networks. The mobile client includes a host of intuitive controls that make remotely controlling computers much easier than with free iOS RDP and VNC apps. A Windows-ready keyboard complete with start button, ctrl, del, and esc keys is included as well as a virtual mouse with right and left clicks and drag & drop abilities.
Remote Control and Remote Administration
As always, DRS is packaged with Mini Remote Control the award winning remote access tool that has made the lives of countless IT pros easier for over 10 years. DRS also includes a set of remote administration tools like Active Directory management, Windows administration, and support for Intel vPro with AMT.

If you’ve got an older version of DameWare Remote Support or some licenses of Mini Remote Control, now is your chance to make the leap to the latest version. Visit www.dameware.com to learn more about v10 of DameWare Remote Support.
As system and security admins, we tend to monitor server logs in order to understand various system activities so we can isolate faults, security breaches and policy violations. However, it’s also necessary to explore workstation logs for advanced system and user activity monitoring.
Workstations are arguably one of the most vulnerable entities on your network. They process content from the Internet and email, they come in contact with infected files, external mass storage devices, and can connect to insecure networks over Wi-Fi.
Workstations generate a wealth of log data that provides detailed event information from the endpoint perspective. While server logs remain paramount to monitoring system and user activity, monitoring workstation logs in addition to server logs makes event analysis and user activity awareness even more comprehensive and actionable.
So, What Makes Workstation Logs Vital for Network Security?
There are various security events that can only be understood with the help of log data generated by workstations. These security events include:
Some Vital Error Codes Found in Windows Workstation Logs for Event ID 4776:
Workstation logs are the easiest means of event awareness that can be used to monitor end-user activity on enterprise workstations, and provide a rich array of security event information. This information will help you create an enterprise audit trail, perform forensics and root cause analysis, and detect threats.
SolarWinds Log & Event Manager for Workstation Log Management
SolarWinds Log & Event Manager (LEM) is a full-function SIEM solution that extends comprehensive log collection, correlation, analysis, and incident response to both servers and workstations.
SolarWinds LEM also has out-of-the-box system-based and user-based active responses to counter threats, troubleshoot issues, and react to policy violations on your workstations.

\Welcome to SolarWinds blog series “Diving Deeper with NetFlow – Tips and Tricks”. This is the third part of the 6 part series where you can learn new tips by understanding more about NetFlow and some use cases for effective network monitoring.
In the previous blog, we had discussed about Network Anomaly Detection and how NetFlow helps network administrators analyze and monitor network traffic efficiently. In this blog we will dive into the impact of cloud applications on networks and how you can track your cloud performance while effectively monitoring your network.
The growing demand of cloud based applications and its increased rate of adoption despite has resulted in massive pressure on network administrators. It is imperative that enterprises maintain continuous network uptime for necessary operational processes. Any issues with the network or the speed of service may have adverse business effect.
One of the biggest impacts of cloud applications, is on a network’s bandwidth and the Software as a Service (SaaS) based approach means you need to ensure enough bandwidth is available for business critical applications to run uninterrupted processes 24x7. Network downtime may cause operational losses and may affect the organization’s bottom line. Some of the problems that network administrators face when using hosted cloud applications are:
Ensuring continuous Cloud application usage
Analyzing NetFlow data helps to monitor network performance as continuous uptime is an absolute necessity for the businesses who use or host cloud applications. It is important for network administrators to lookout for bottlenecks, bandwidth hogs, and unauthorized protocol and application priority. NetFlow data carries information on:
NetFlow gives network administrators insight and helps them to prioritize hosted applications and deploy Quality of Service (QoS) policies. It provides the means to track the cumulative usage of a given application in an aggregated manner, down to specific regions, if necessary. As a result, the NetFlow information can be used to verify whether the cloud usage behavior matches with your service level agreement by mapping your actual activity between the cloud and your network. Measuring latency is challenging while operating on cloud, by using flow exporters like nProbe you can identify bottlenecks by analyzing the data through NetFlow collectors and demand the cloud provider the promised service.
Using NetFlow Traffic Analyzer, you can monitor real-time network utilization and traffic patterns, and understand who or which applications are consuming the most bandwidth thus ensuring it is used accordingly. To learn more about NetFlow, check out our NetFlow V9 Datagram Knowledge Series.

Storage Manager allows users to access the Storage Manager Database via the Storage Manager Website. This feature can be useful when you need to run queries against the database.
Note: It is recommended that you perform a full backup of your database before running any manual queries.
Accessing the database simply involves changing the Storage Manager URL. We have two options for accessing the database
- RunScriptServlet - Allow us to run queries to the database
- DatabaseAdmin - Allow us to run queries to the database and also give other useful information about the Storage Manager database
In the screen shot below, the URL for the Storage Manager website is "http://10.110.68.112:9000/LoginServlet."
To open a window to the Storage Manager Database we would change the URL to the following:
See screen shots below.
The following example will terminate all instances of notepad.exe on an alert status of Down using PowerShell:
Following is an example that terminates all running instances of notepad.exe.
Note: You will need to enable impersonation through your PowerShell script or run the Advanced Alert Manager under a user account with elevated privileges.
That is a question.
This is probably not relevant for a great number of IT folks, but it is interesting for the implications on server room/server cooling.
This year some enterprising researchers developed a micro cryocooler that can cool a device down to 30 Kelvin (-243 °C, -406 °F) in around an hour and is about the length of your pinkie finger. This new cryocooler device is a multi-stage, mini version of the tried and true Joule-Thompson cryocooler (circa 1852). The Joule-Thompson cryocooler cools by causing a high-pressure gas that is below its inversion temperature to expand as it flows to a low-pressure region.
The first stage of the new device uses nitrogen so it can cool from room temperature to 100 K (-173 °C, -180 °F) . The second stage uses hydrogen, and cools the rest of the way to 30 K.
As it stands, this is a great innovation for medical technology and space technology (such as interplanetary telecommunication).
Now, if we can cool down to 30 K, we should be able to regulate temperatures to a happy medium between temperatures needed for superconducting devices and temperatures too hot for business-level computing. I, personally, would be very grateful for an inexpensive, consumer-level CPU cooler for my laptop.
In the meantime, you can use SolarWinds Server and Application Monitor to keep an eye on your server temperatures and wish you had a micro cooler for your CPUs, cryo or otherwise.
