SolarWinds is pleased to announce that latest and greatest version of IP Address Manager (IPAM) 4.1 has been recently released.

 

This new version primarily focuses on monitoring and management of high-performance DHCP service from ISC via IPAM web-console. 4.1 namely brings following new features:

 

  • A new re-designed DHCP management UI that helps to manage multiple methods of organizing IPs across Windows, CISCO and ISC DHCP vendors
  • Management of ISC DHCP subnet options, ranges and pools (New to ISC)
  • Monitoring of ISC shared network containers and their subnet utilization
  • Monitoring of ISC DHCP IP address static assignments within groups


But that's not all. We were listening to you, our users who requested support for more complicated configuration scenarios on DHCP servers. This advanced scenarios typically requiring setup for specific DHCP Options. IPAM v4.1 can namely do following:

 

  • Monitor and manage over 180 (RFC 2132) DHCP options on Cisco, Microsoft and ISC DHCP servers
  • New UI for DHCP options management with data type validator and text translation of numeric value of each option (you don't have look into RFC)
  • Automatic detection of supported/unsupported options per DHCP vendor
  • Both-way sync between IPAM and DHCP server.

 

For example, you may use options 66 & 67 in order to setup TFTP and VoIP config file name for your VoIP infrastructure running on DHCP server.

 

You may find additional information about fixed bugs and related details in IPAM V4.1 Release Notes

 

If you are interested in how the UI looks look like, here is a small summary:

 

1) ISC DHCP monitoring with shared subnets container

GA ISC.png

 

2) Create/Edit ISC DHCP Subnet - add pools, ranges or setup DHCP options

IPAM 4.1 is available on your customer portal for a download and upgrade on production servers.

Many of you are patiently waiting for new version of VNQM and hope to see support for Avaya call quality monitoring. Well, now is a good chance how to help us recognize technical differences and challenges our engineering needs to solve before GA. We are here with first beta that supports Avaya call managers (have S7x series in our lab). We would highly appreciate if you can try to install this version on your test environment (could be VM) and let us know how it works on your end.

 

This is currently supported functionality:

  • Avaya support
    • Storing CDRs in Orion internal DB
    • VoIP search for Avaya calls (search with time and CM only)
    • VoIP Call details view (without CQR and Call Signaling)

 

If you want to participate in beta, you should own VNQM and be under active maintenance. Then you need to simply agree with this beta agreement: SolarWinds VoIP & Network Quality Manager 4.2 Beta Participation Survey and I'll send you download link.

 

How to add Avaya call manager? Click on "Add new call manager" button on IPSLA Summary page and our wizard will take you through the process.

 

I'd also welcome any feedback on wizard UI and improvement points.

 

Here are few screenshots:

When I talked to you - IPAM users, I've heard many times that one of the typical tasks of IP address management is obtaining available IP address(es) for selected subnet. This is tricky if you use spreadsheets and share it with more people (you never know if the doc is in sync and if you won't create IP address conflict).

 

You also voted for similar feature - IP Request Form on Twhack. Where one of the scenarios is ask & approve assignment of first available address in subnet.

 

In this post, I'd like to unveil an IPAM API method that can give you one or more Available IP Address in a subnet.

 

What we need in order to accomplish this trick:

 

  1. IPAM 4.0 (could be an Eval)
  2. Latest version of Orion SDK installed on the IPAM server.
  3. Access to Windows PowerShell (could be applied on Python, Perl or VBScript as well)
  4. User and Password into IPAM
  5. Ten minutes of your time :-)

 

Install and configure your IPAM

Simple start, install and configure your IPAM. It must contain at least one subnet with IP addresses and their statuses inside:

 

Install your Orion SDK

Orion SDK will provide API access to IPAM database via secure methods. I don't expect any single problem during install process (link for download). My recommendation is to install as local Administrator.

If you run into any problem, please speak up in this forum on Thwack.

 

Open your PowerShell window

And now the real fun begins. Run your PowerShell Window and make sure that Orion SDK was successfully registered:

Type this command: Get-PSSnapin | where {$_.Name -eq "SwisSnapin"}) and hit enter key.

The result should looks like this:

 

If you didn't get this, simple type following command (will add PowerShell snappin from SDK)

Add-PSSnapin "SwisSnapin"


Now you have to setup connection to your database/IPAM.

Type in following commands and change your $hostname to domain name or IP address of your IPAM, $username to the username you want to use for connection and $password to your password (like $password = "solarwinds"). If you are using Eval of IPAM and running the script from the same machine, keep it as it is below.


$hostname = "localhost"

$username = "admin"

$password = New-Object System.Security.SecureString  

$cred = New-Object -typename System.Management.Automation.PSCredential -argumentlist $username, $password

$swis = Connect-Swis -host $hostname -cred $cred

 

OK, so we set up the connection, and now we can call an API method and get information about available IP Address. You also need to know the name of the subnet from where you want to get free IP Address. In our example I'll use "DEV" name (see screenshot above). Type in the command below and hit enter key:

 

Get-SwisData $swis 'SELECT TOP 1 I.Status, I.DisplayName FROM IPAM.IPNode I WHERE Status=2 AND I.Subnet.DisplayName = ''DEV'''

 

Et voila:

 

As you may see we got first free available IP Address as 10.140.126.4 with status "2" (Available") which corresponds to my sample IPAM data:

OK so that's good, but I don't assume that you'll want to run such background script every time you want to get your first available IP Address. You can certainly save the whole script into a file and then run it just by simple click (feel free to download my example).

 

The result of the "Get-SwisData" is stored in DataSet - .NET object which you may use for further processing. For example, you can store the results to the file or you can call it from the web service or helpdesk system.

 

If you want to iterate via IP addresses in the result, you may use this powershell query (useful when getting more than 1 free IP address or you want to run the query for more subnets):


$addresses = Get-SwisData $swis 'SELECT TOP 1 I.Status, I.DisplayName FROM IPAM.IPNode I WHERE Status=2 AND I.Subnet.DisplayName = ''DEV'''


foreach($address in $addresses)

{

     write-host "Free IP Address is" $address.DisplayName

}

blogpost foreach.png

We can slightly modify SWQL query and populate subnet address and CIDR next to the available IP Address (by the way, this is the beauty of SWQL language, you don't have to use JOINs in many cases, simply use dot notation in order to list properties of related entity - in this case "Subnet"):

 

$addressesWithSubnets = SELECT R.Address as SubnetAddress, R.CIDR, R.FriendlyName, R.PercentUsed,

(SELECT TOP 1 I2.IpAddress FROM IPAM.IPNode as I2 WHERE I2.Status=2 AND I2.SubnetId = R.GroupID ) AS FreeIpAddress

FROM IPAM.GroupReport as R WHERE R.GroupType='8'

 

Where GroupTyp=8 means type "subnets" (not supernets or DHCP scopes,etc.)


Then the result may look like this:

subnets-script.png

 

I can iterate through the $addressesWithSubnet variable and do whatever I need witch each record, for example send email, send data into help desk, update database (custom property) or store it into a file.

 

The interesting option is create a webservice that can call this IPAM powershell script with attribute "subnet name". Then you can ask for first available IP address from anywhere.

 

Example where simply writing each row to the console output:

list of subnets.png

Download the full script.

 

Example of .NET webservice that can call our PowerShell script:


[WebMethod]

//When calling the method put the path to our script file as parameter to the method GetFreeAvailableAddress.

//For example: c:\script\getFreeIP.ps

//Feel free to add exception handling you prefer.


public void GetFreeAvailableAddress(string script)
{
  
RunspaceConfiguration rC = RunspaceConfiguration.Create();

  
Runspace runspace = RunspaceFactory.CreateRunspace(rC);
   runspace
.Open();

  
RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);

  
Pipeline pipelineCommand = runspace.CreatePipeline();
   pipelineCommand
.Commands.AddScript(script);

  
// execute the script
   pipelineCommand
.Invoke();
}

 

Integration with SAM (Server and Application Monitor)

One of the easiest way to get Powershell script monitored by Orion web interface is via SAM (try eval if you don't have it). SAM can monitor powershell scripts and show the results on the web very simply.

 

I had to just re-format the output of my PowerShell script and then define new PowerShell template in SAM so it can transfer the data from script on web.

There is a very nice article about how to add Script Monitor into SAM. So I'll skip this phase and just summarize that what you need to do on your Script side, is populate data you want to show via two specific messages:

Detail Type

Required

Meaning

Statistic

Yes

A numeric value used to determine how the monitor compares to its set thresholds. This must be an integer value, (negative numbers are supported).

Statistic.Name1: 123

Statistic.Name2: 456

Message

No

An error or information message to be displayed in the monitor status details. Note: Multi-line messages are supported. To use this functionality print each line using a separate command. For example:
Message.Name1: abc

Message.Name2: def

and it must end by "Exit(0)" statement.

 

I modified our script in order to produce messages that are parsed properly by SAM (how to add add new SAM template). The template show you percentage used of IP address per subnet and also first free IP Address for each subnet.


Section added


Write-Host "Message.$($freeIP.FriendlyName): Subnet: $($freeIP.SubnetAddress)/$($freeIP.CIDR) named: $($freeIP.FriendlyName) has this available IP  ADDRESS$($freeIP.FreeIPAddress)";   

Write-Host "Statistic.$($freeIP.FriendlyName): $($freeIP.PercentUsed)";

 

Feel free to download SAM template from here. Wondering how the result looks like on the web? Here it goes:

Let me know if you have any questions and don't be intimidated by our API, it's very easy to use.

I'm happy to announce that IP Address Manager 4.1 RC1 is available for download and installation on your production servers.

Except bug fixes, there are two new big features we added into this release of IPAM:

 

  1. ISC DHCP management and monitoring
    • Create, edit or remove ISC DHCP subnets directly in IPAM using the same UI as for Microsoft or Cisco DHCP
    • Manage ISC DHCP subnet options, ranges and pools (RFC standard options, including options 66 & 67 for VoIP settings)
    • Default alerts for high DHCP subnet utilization
    • Monitoring of ISC DHCP shared subnets and their utilization
    • Monitoring of availability of ISC DHCP servers and their subnets (up, down, unreachable)
    • Monitoring of ISC DHCP IP address static assignments within groupsall DHCP vendors.png
  2. Support for management of standard DHCP scope options on Microsoft or Cisco DHCP servers
    • Setup VoIP options (66 & 67) on your DHCP scopes
    • Manage all RFC standard DHCP options using web UI that describe usage of each option.
    • Automatic both-way DHCP scope option sync between IPAM and DHCP servers

 

The installation is available on your customer portal or via this RC agreement (IPAM 4.1 RC Participation Survey).

 

You should contact SolarWinds support in case of any problems or bugs you found.

 

We are looking to your feedback on this latest version.

In the last release of VNQM we brought the VoIP troubleshooting for your Call Managers. Those of you who maintain VoIP company infrastructure are probably familiar with the VNQM call signaling topology resource:

callDetail_gateway.png

This resource contains devices "1005 & 1041" which are typically gateways. These devices connect your internal VoIP sub-system to the line of your data/voice provider(s). You may typically hear "PRI or PRI Gateway" when talking about inside out or outside in VoIP connectivity. What is PRI? The definition says that PRI (Primary Rate Interface) is a telecommunication standard used in the Integrated Service Digital Networks (ISDN), for carrying multiple DS0 voice and data transmission between two physical locations. More technically, a PRI is a type of VoIP line that provides up to 23 separate 64 Kbps B lines and one data channel like with 64 Kbps in a T1 configuration (typically USA) or 30 B lines and one data line in a E1 configuration (typically Europe).

 

PRI is quite popular today among businesses because of many benefits it has:

  • Scalable technologies that can grow or shrink with your business
  • Low cost
  • Use of existing PBX system technologies
  • Multiple sites can be connected into the same system eliminating maintenance and installation charges across locations
  • Doesn't impact end-users (can dial the number as they were used before)
  • Increased high-tech communications options
  • Can be managed remotely via web-based consoles

And this "PRI Gateway" is something that VNQM 4.1 can now monitor and brings you an another piece of information to solve your VoIP problems. To be very specific, in the case of VNQM 4.1 it's about Cisco devices (MGCP gateways) that have support for PRI.

You, Thwack users, had many dicussions or feature requests (here or here), about how to see utilization of your PRI trunks. You could also read about PRI in a Geek Speek blog post .

VNQM 4.1 RC is ready to be installed on your production and it is fully supported by SolarWinds support. If you are a IPSLA/VNQM active maintenance customer you are more than welcomed to sign-up here for a RC download

 

What Do We Need to Monitor?

A typical monitoring task for the T1/E1 is to monitor a number of active channels/trunks and their utilization. Some of you were also asking for monitoring of "VoIP vs. Data" ratio on the line. VNQM 4.1 can do both now. We don't use SNMP in this case, because Cisco has a bug in their SNMP implementation which results in incorrect trunk call utilization data being reported.

 

Now, how do you see this data in VNQM?

  1. Use a new gateway wizard to add your device to be monitored as the MGCP gateway at VNQM settings page

 

add gateway_cr.pnggateway wizard.png

 

  2.  When you have successfully added, you should see the list of your gateways on the VoIP summary page:

gateway summary.png

3.  Click on the Gateway from the resource above or in the signaling resource that's part of the call details page. This will take you to the brand new Gateway detail page:

Gateway detail page_cr.png

 

How to see data distribution and PRI trunk utilization - are you paying too much to your provider?

Gateway detail page_cr 1.png

Data distribution chart can show you a total usage on your PRI gateway, data & VoIP traffic

distribution and you can also drill down to see each trunk utilization specifically. "Trunk Utilization" resource will give you a good historical overview where you may see spikes or gaps over a time.

In our case, we can see that more than 37% of the capacity

is not used over last three months. So why to pay so much to your voip/data provider?

You can reduce amount of lines you need for the connectivity with the outside world.

The same chart could be also used for a troubleshooting of call connectivity.

In a case you reach maximum PRI utilization, your calls can't be connected

and it's time to figure out who is causing such load (CDRs), ask your provider for more bandwidth, or, at least, set up VoIP precedence policies. Gateway detail page_cr - 2.png

 

 

 

 

Want to see more "per trunk" utilization details? Not a problem:

Gateway detail page_cr_cr - 3.png

 

 

 

 

How to see problems on a gateway?

It's possible to do it via VNQM search page itself. But, you can save some time and see the most important metric - failed calls, and call quality issues directly on each Gateway detail page:

Gateway detail page_cr_cr - 5.pngGateway detail page_cr_cr - 4.png

In order to see call details, phone numbers, etc. simply hit "Search for all failed calls" link at the bottom of the page and VNQM will filter out Gateway relevant calls only."Easy peasy" don't you think?

PRI & trunk utilization monitoring is a major feature of this release. However, VNQM 4.1 also brings a new web-based reports with charts you may read about in this post.

See you there.

New IP Address Manager 4.0 just has arrived. The upgrade is available for free for all IPAM customers under active maintenance and can be downloaded from the SolarWinds customer portal.

 

The 4.0 comes with following list of new features and improvements:

  • Support for BIND DNS management and monitoring
    • Create, edit, delete DNS zones and DNS records for BIND DNS v8.x and v9.x (A, AAAA, MX, PTR, CNAME)
    • Monitor BIND DNS service status
    • Monitor BIND DNS zone status
  • Active IP Address conflict detection in both static and DHCP environments.
  • Integration of IPAM with our UDT product via subviews
    • See Port and User information on the same page as IP address Host or DNS assignment history
    • Shutdown port remotely in case of IP address conflict (UDT functionality)
  • New Icon pack for IP addresses, DNS zones and DHCP scopes.

 

Some of you may read IPAM 4.0 RC blog post that presents BIND DNS management and monitoring and IP Address conflict detection. For thos who didn't, here is a short summary:

 

BIND DNS Monitoring and Management

BIND DNS is de-facto DNS standard and it's frequently used among IT guys. Those who need to configure BIND DNS via CLI know that there is a lot of space of human mistake during adding new DNS zones or updating DNS records. I can also imagine that admins are not comfortable with giving CLI credentials for read/write/create/modify BIND config files to people that just need to maintain DNS records. And that's why we added support for BIND management into IPAM - no more errors during config and no more sharing of CLI credentials.

 

Adding and configuring BIND DNS servers is a matter of few minutes. As a user, you need to do three steps:

  1. Add device that hosts BIND DNS as a node into IPAM (that will also allow you to monitor device performance)
  2. Let IPAM to scan BIND configuration (enable scanning)
  3. Allow/Deny other users to change BIND configuration (Power User role and above can do that).

Active IP address conflict & User Device Tracker integration

IPAM 4.0 can detect IP Address conflicts (both IP static and DHCP environments) and help you to troubleshoot the problem. It would allow you to switch down the port remotely if you have UDT installed along with IPAM. Let's take an example of IP conflict and how IPAM may help you:

 

Client_conflict wireless.png

IPAM 4.0 offers following IP Address Conflict detection and historical data in order to help you identify devices in conflict.

  1. IP Address conflict is triggered
  2. IPAM contains information about the IP Address history assignment from where may user see MAC addresses that are using IP in conflict
  3. If UDT is installed, UDT view provides information about Device, Port and Active Directory information.
  4. UDT can remotely shut down switch port and unblock IP in conflict.

Latest and greatest version of NPM 10.5 is ready for download from your customer portal.

 

Here are major improvements and new features:

  • Routing information including alerting for major routing protocols (RIP, OSPF, BGP)
    • View and search in routing tables.
    • See changes in default routes and flapping routes
    • View router topology and neighbor statuses
  • New Interface filtering UI to import discovery results:
    • Exclude virtual interfaces and access ports, or specific interface type
    • Select interfaces based on pattern matching including Regex formulas
    • The new preview UI for final selection of imported interfaces
  • Multicast traffic information monitoring and alerting, including topology information.
    • Automatic detection of multicast protocol and multicast group import into NPM
    • Display multicast information, route information, and device information in a single unified view
    • View multicast topology using upstream and downstream device list information
    • Generate intelligent alerts based on multicast errors
  • Interface Auditing
    • View user actions related to interface monitoring in NPM

 

As you may notice from above, this version of NPM adds another important element for successful and effective troubleshooting of connectivity and performance issues - monitoring of OSI L3 routing protocol information.

 

How does routing information impact network performance and availability?
     IP networks are critical for business missions, it’s not only router or switch hardware which can impact your network availability and performance. It’s also Incorrect routing or routing issues causing undesirable performance degradation, flapping and/or downtime. Getting such information requires “analytic tools”. In bigger network, routing can change very dynamically (adding/removing switches, Aps, VPNs, routers and IP subnets) and it’s almost impossible to monitor routing changes from the inside of the routers (too much simultaneous data).

 

Also, information like “Flapping Route” are not available for most of protocols directly on the server. The flapping route problem will cause frequent re-calculation of network topology by all participating routers or flood network with many Update packets. In both cases it prevents the network from routing and correct packet addressing. Another common issue is human error caused by incorrect creation of static routes. ICMP Ping won’t help you and since you can see that the device is up and running but you really need to see routers settings and check packet routing.

How is routing presented in NPM?

     If NPM recognizes that Node is actually a router that runs one of the OSPF, BPG or RIP protocol it will automatically gets routing information from such device. Routing information is then mapped to existing Nodes and Interfaces in NPM so you may see device availability statuses and network performance data. All new resources are under "Networking" tab on Node detail page.

RoutingGA1.png


NPM 10.5 also automatically detects multicast protocol traffic and imports multicast groups as a monitored object.

What is multicast?

      IP multicast is widely deployed in enterprises, and multimedia content delivery networks. A common enterprise use of IP multicast is for IPTV application. It’s also used for video and teleconferencing and it is about to transmit a single message to a selected group of recipients. A simple example of multicasting is sending an e-mail message to a mailing list. Mutlicast protocol is well known as a bandwidth-conserving technology that reduces traffic because it simultaneously delivers a single stream of information to thousands of recipients.


How to understand multicast availability and performance information?

     Because the topology is sometimes complicated it’s difficult to understand who can and who can’t receive multicast traffic. The network availability is a key and the status of the whole multicast group is a representative of (not)successful transfer of multicast stream.

Even though Multicast is designed to save bandwidth utilization, with many groups and many multicast sources & receivers, network may become saturated very quickly. There are tools like NTA which can sniff the network data and tell you what apps are causing the network traffic but people usually need to quickly read multicast node traffic utilization – bits per second. Looking at overall traffic consumed by multicast node, users may see the ratio of multicast vs. another type of traffic on the network and then optimizes QoS configuration to increase/decrease traffic priority, upgrade the link or change multicast routing so the traffic may go via another line. In a case that the multicast group status reports a problem, people need to have an information about Multicast Topology. Only topology information allows you to quickly jump between Upstream or Downstream device and let you find the root cause of the problem fast.


How NPM 10.5 solves Multicast problem?

     During first network scan, NPM detects multicast groups and list of nodes that are subscribed to each one.

multicastGA1.png





















multicastGA2.png
 
NPM then creates a topology of upstream and downstream devices within a group and detects interfaces that forward or receive multicast traffic.

multicastGA3.png

Re-worked Interface filtering page

     This is something you've asked us to improve (for example here or here on Thwack). We understand that filter & import only desirable interfaces took some time with previous version of the Interface discovery filter. If you run Discovery Importing wizard in NPM 10.5 you'll find re-worked UI for interface importing. You can filter by Interface status, VLAN port type, protocol type, hardware type. It now has support for advanced filtering and Regex conditions so create filter that will import just physical interfaces that are part of the specific VLAN ID is a matter of few seconds.

interfaceFilteringGA1.png


I believe that you will like the new functionality of NPM 10.5 and stay tuned, because we are already working on the next version.



We know that IP Address Management is more and more important because networks became much more flexible, dynamic and people are used to bringing their own devices into corporate networks. If you've seen your What we are working on after 3.1, you won't be surprised that the new IPAM 4.0 beta contains support for BIND DNS, active detection of IP Address conflicts and better integration with User Device Tracker.

 

Active IP Address conflict detection

IP Address conflict is a typical nightmare of admins. IP Address conflict occurs if there are two or more devices in your network and have the same IP Address configured.

IPConflict1.png

Conflict.png

This is an issue that could arise on devices across any operating system that connects to a local area network (LAN) across any operating system, wired or wireless.

 

What problems may IP Address conflict cause?

Primarily network connectivity issues. Impacted machines are loosing internet access or general network connectivity until the conflict is resolved. It can impact laptop, VoIP phone or application server.

 

What causes IP Address conflicts?

There are three typical scenarios:

 

  • Bring Your Own Device phenomenon

    Typically happens when you bring your laptop or tablet from home to the work and you still have the "home" IP address assigned which can cause collisions within corporate network. It's also typical for business trips when you got assigned static IP in the hotel and then you come back to work. It may also occur in Virtualized environments like spin up VM clone in the same subnet when virtual machine has a statically assigned IP.


  • DHCP servers & their configuration

    Two DHCP servers are managing the same IP subnet/segment with overlapping IP addresses and DHCP server doesn't check the network IP status (IP used or not). IP address conflict happens when one machine already has a DHCP address assigned from the first DHCP server and another device is given the same IP address from secondary DHCP server. This could be a typical problem in "load balancing" DHCP configurations.

 

  • Human mistakes during IP address assignments

    When admins do not use any IP address management tools it is so easy to assign already used IP address to the new device on the network.

 

How to manually solve IP address problem?

First, you need to know who caused the conflict and find the MAC addresses that are in conflict. If you have such possibility, unplug device which should have correct IP address. Then use 3rd machine within the subnet to PING the IP address in conflict. Use "ping -a x.x.x.x in order to get two important values. First DNS name of machine which causing the conflict, second TTL value, which may help you to identify operating system. For example Windows has typical TTL 128, Linux may have TTL 64. You may find the whole list here.

ping1.png

It may happen that there is no device name provided or ICMP protocol is blocked by firewall. In this case, you may use "arp -a" command and list MAC address assignment for your IP address:

arpa.png

MAC address is useful information, because you may identify the vendor of that device. MAC address are unique and each vendor has the first three octets of MAC are reserved for identification. You may find the MAC vendor pre-fixes list here.

 

With MAC address information, you may do go to the switch and block related port, or block that MAC on your wireless router/AP and let origin device to use its IP address.


How to solve IP address conflict with IPAM 4.0 Beta?

 

As I stated above, IPAM 4.0 can now actively detect IP address conflict. We primarily focused on alerting and information about MAC addresses which is a key-point information for conflict troubleshooting. IPAM actively scans the network and if it detects duplicate static IP assignment or duplicate IP provisioning form DHCP server, it will trigger an alert with conflict information:

IPConflict.png

Once you see IP Address in conflict, simply click on the IP or MAC address info in the alert message and it will take you to the IP address detail page, where you may see MAC address assignment history. Another IPAM 4.0 improvement is better integration with UDT product. So you may directly see device & port where are machines connected.

 

You may use IPAM Message Center too and get all history of IP Address conflicts:

messageCenterAlert.png

UDTSubviews.png

As you see, you no longer need to use multiple commands via CLI or use 3rd machine to ping who is IP address in collision. More than that, you can see connectivity details including port and user information on one screen. Now you can use for example NPM which can remotely shut-down interface and disconnect the device from the network, or simply connect to the switch and block that port via CLI. Also, because IPAM uses alerting engine you should get IP address information before impacted person creates IT ticket (which will take some time while disconnected from network)

 

BIND DNS Monitoring & Management

 

BIND DNS is one of the most used DNS solutions. IPAM 4.0 now adds support for monitoring and management of BIND DNS services on Linux. You can now manage your Microsoft DNS and BIND DNS via one web-console. IPAM supports all important DNS tasks like automatic monitoring and management of DNS zones, two-way synchronization of DNS records and DNS server availability.

If you want to add your BIND DNS server into IPAM use short wizard that will lead you through the process of addition. When added in IPAM, it will sync and import actual BIND DNS configuration and then you can monitor or manage zones & DNS records:

IPAM 4.0 Beta is ready to be tested. All users under active IPAM maintenance may get Beta build and try it for free on non-production environment. If you would like to try it, simply fill this IPAM Beta Agreement.

As always, we also have Thwack IPAM Beta forum and it would be great to get your feedback there.

 

Thanks!

I'm happy to announce that NPM 10.4 release is officially here. This version is literally packed with new features! All current NPM customers under active maintenance can download the upgrade from their customer portal.

In the past few months you could vote what features you would like to see in your favorite network monitoring software, NPM, vNext and we were listening. 10.4 comes with the most wanted ones:

We migrated the custom property editor on web. Now it's part of the main Orion webconsole and accessible from NPM and other SolarWinds Orion family products. New intuitive wizard will take you through the process of creating new custom properties.You can also specify a list of pre-defined values to minimize entry errors.

Audit Tracking

Version 10.4 comes with user auditing feature. You can now monitor who made what action/change in NPM. New auditing functionality is fully automated, you don't need to set up rules or policies it works immediately after installing 10.4. All information is available through Message Center where you can filter, sort and see all the details. You can also see a new Top 10 resource on summary page:auditing1.png

 

Hardware Health Monitoring for your network devices

SAM users know how useful is the hardware health of their servers. NPM users didn't have out of the box support for that (they had to use custom pollers) to monitor critical hardware parts of routers or switches like Fan speeds, temperature sensors or health of power supplies.

                                                                                                                      

NPM 10.4 now allows you to prevent hardware malfunctions by monitoring your hardware with more details. We added support for Cisco, Juniper, HP, BigIP F5 and Dell networking devices. You can also set an alert to be notified if some sensor exceeds a threshold and you can track historical data

 

HWhealthActual.pngHWhealthStatistic.png

 

Looking at the hardware health historical chart reminds me that NPM network monitor has been completely migrated to the new "drag & drop" chart engine so you may use interactive features like zoom-in or switching on/off chart data on every single chart now.

 

Out of the box support for BigIP F5 devices

 

BigIP devices are widely used and they are bit special compared to other networking hardware. CPU and memory polling is not enough for F5 effective troubleshooting. The important highlevel metrics are Throughput  Connections (SSL, opened) and Failover status. If you are interested to see more details NPM can provide you with the list of Virtual Servers, Pools and Nodes. All these lists carry information about IP address and element status.

A lot of cool network management stuff don't you think? But that's not all there is decent set of another features waiting for you.

 

UI improvements - Subviews

 

We know that it's hard to make everyone happy with how we categorize and group items in our NPM webconsole menus. Sometimes you need better granularity and possibility to group particular data into some kind of tab or bookmark. NPM 10.4 now supports concept of "Subviews". This UI enhancement is there mainly for better organization of your views and gives you freedom for creating your own categories on website. It also speeds up the web by allowing you to focus on the resources you really need to load instead of loading every resource every time. Subviews are displayed as a left navigation menu that allows you to quickly go to different views for a node. You can enable Subviews by clicking Customize Page then the "Enable left navigation" button.

 

Subview+1.PNGSubview+2.PNG

 

As you can see you may create your own tabs anywhere, NPM 10.4 also comes with pre-defined subvies in order to help you with intuitive navigation.

Let's continue with another important enhancement.

 

Universal Device Poller (UnDP) improvements

 

UnDP - something that NPM users know very well. NPM didn't support multiple device pollers in a single chart. This is useful when you need to correlate trends between various metric from your device (temperature vs. CPU frequency vs. fan speed). 10.4 gives you the possibility to define new type of chart where you can put various UnDP pollers on your "Y" axis like this:

 

You can simply click "Add More" and select your existing custom poller. Then you need to define units for your data. NPM can automatically convert some kind of units into higher or lower metric (for example bytes to Kb) so you can read it on your chart without counting zeros. This chart also runs on the new engine so you can use zooming and other features.

Another useful improvement for UnDPs is UnDP Parse Transform function. This is little bit advanced feature to use. It is especially useful when you have custom pollers that return a text string and you have to parse the text string to remove the number and use it in a transform function. If you want to use it, go to the UnDP application (Windows start menu -> SolarWinds Orion -> Network Performance Monitor -> Universal Device Poller) on the NPM server. For the formula use the following syntax: parse((REGEX,{POLLER}) as you can see on the picture bellow.

UnDP+Transform+Parse.PNG

The regular expression you need will depend on the string you are trying to parse.

We also tweaked UnDP polling retention settings capabilities. If you go to the UnDP settings you may now change the polling interval for each pollers type and also define retention period for the UnDP statistic data and summaries.

UnDP+Retention+Settings.PNG

 

Those are just most visible new features in the new Network Performance Monitor. I would like to briefly mention other important and useful features:

  • Support for Microsoft Windows 8 (for evaluation purposes) and Windows Server 2012
  • Native support for HP MSM 760/765 wireless controllers.
  • De-duplication of nodes with the same IP address

 

You may also see release notes for the list of bugs we fixed.

 

As you can see, this release is really big one and I would like to thank you - our great Thwack community for your contribution and willingness to help us understand what problem do you need to solve. Thanks!

If you are an active user of IP Address Manager and User Device Tracker, you know that having port, IP address & connected user information is important during troubleshooting. Understanding of who is using given IP address and where an IP address is physically connected is critical for IT engineers so they can focus on specific device or user if needed. It is also important if an user that is currently using such IP address is expected to use it according to your IP subnet rules. IPAM and UDT are well integrated via single web console but there is a way how you can see UDT related information directly within your IPAM subnet detail page and save your time.

 

IPAM and UDT already have this data so we prepared a small script that can help you to see port, AD account or port history link directly in one row in IPAM. So the output may look like this:

scriptImageSetup2.png

 

2012-10-22_2148.png

 

 

If you are missing a module, download links are provided for evaluation - only IPAM and UDT are required.

This script will allow you to pull data from modules other than UDT also (NetFlow for example). If you are a skilled power shell user, you may edit our script and modify the data you would like to see in IPAM. It uses custom properties so it should be something you are familiar if you have used IPAM before. IPAM custom properties are bit different than custom properties you may know from NPM or SAM. IPAM has "string" and "url" types of custom properties.

 

First, you need to meet these requirements before installation:

  1. You need the Orion SDK - download here. Please refer to SDK setup issue or how to set-executionpolicy unrestricted articles in case of issues.
    • Create ALL of the following REQUIRED custom fields/properties in IPAM exactly as you can see below:

    Now it's time to open the script and fill in credentials and variables (the pink text in the image below):


    scriptImageSetup4.png

    • IPAMDBUsername – The username used to connect to the IPAM Database
    • IPAMDBPassword – The password used to connect to the IPAM Database
    • IPAMdbServer – The IP address of the IPAM Database server
    • IPAMdatabaseName – The Name of the IPAM Database
    • integratedAPIServer – The IP address of the IPAM server
    • integratedAPIUserName – Account used to login to the webconsole - with permissions to all modules
    • integratedAPIPassword – Password used to login to the webconsole


    Once you prepare your credentials you can run the script.

    You should run the script from windows command line (open the Windows Start menu -> All Programs -> Accessories -> Command Prompt). You need to run the script a couple of times to make sure all of the credentials and properties setup correctly.  Once you have done that you should be able to schedule it as a recurring windows task.

      • NOTE: The script will tell you how long it took to run… a good idea or the best idea is to not schedule it to run more frequently than the time it takes to complete.
      • EXAMPLE: If it takes 5 minutes to run, I would schedule it to run every 30.

     

    The final step is to configure the UI and display your new columns in the IP Address view. Click on the column and select new custom properties from the list.

    scriptImageSetup3.png

     

    If you want to see data from SAM or SEUM you may modify script and your custom properties accordingly.

     

    DISCLAIMER: This script offers a great sneak peek at integration we’re working on productizing and we’d love to get your feedback on this concept – see this IPAM post for more info.  HOWEVER, we must point out that this script is NOT officially supported by SolarWinds support and they will NOT take cases on this functionality.  Any bugs or problems with the script-based integration are subject to thwack forum support ONLY, so please keep that in mind when deciding if it’s something you want to try in your production environment.  Happy testing!

    Hi all,

     

    We have officially reached release candidate (RC) phase for IPAM 3.1.

    If you are an existing IPAM customer under active maintenance, you can install the RC. RCs are fully supported and made available to existing customers prior to the official release.

     

    Our engineering teams are working on the most wanted features in order to help you with DHCP, DNS, IP address management (DDI).

    First, we added support for DNS management. IPAM 3.1 RC can manage your Microsoft DNS services. You can create, modify or delete zones directly from a web console (no more RDP connections to the server):

    DNSZone add.png


    DNSZoneAdd2.png


    Second, you can also manage your DNS records within the same web console - this is very useful when you provision new serves or if you want to look for obsolete DNS records. To do that, click on the "DNS zone" tab and then on the "DNS records" button:


    DNSrecords.png


    Then you will see a list of existing DNS records within given zone. When you click on "Add New" you will see following dialog and supported DNS record types:

    3.1 dnsRecAdd.png


    Your DNS changes are immediately propagated on your DNS servers, also you may see changes from your DNS servers in IPAM.


    Third, we extended DHCP functionality on Cisco devices - including Cisco ASA devices. That means you may manage your IP address reservations, exclusions or DHCP scopes with the same method as you were used to in previous release of IPAM for MS DHCP services. For example, to do an IP address reservation, navigate to your Cisco DHCP scope, pick an IP address that you want to reserve and change its status to "reserved". IPAM will take care of all the background communication with your Cisco DHCP device.

    CiscoASAdhcp.png




    You may also notice improved UI for IP subnets and exclusions for your scopes. This is important in case you want to understand what is the distribution of your DHCP scopes:

    3.1 scopes&split.png



    And finally we added support for split scope scenarios on your Microsoft and Cisco DHCP servers. Split scope actions are widely used for high availability and load balancing performance purposes. You may find it in both Microsoft and Cisco DHCP best practice whitepapers. Microsoft and Cisco don't offer a easy to use GUI to do that. We decided to design a brand new interactive wizard for split scope action. To create a new split scope you need to select an existing DHCP scope under the "DHCP Scopes" tab. You also have to have at least two DHCP servers (so the second server may handle newly created scope). Then you click on the "split scope" button and IPAM will show you the three step wizard for configuration. You may simply use the slider to define an IP address ratio for your existing and new scope:

    10-9-2012 15-59-04.png

    IPAM 3.1 can also poll data about existing scopes from your DHCP servers and it can also detect disabled scopes.


    We are looking for your feedback and the RC is ready for download in case you are an IPAM user under active maintenance. Please follow this link to see RC discussion or participate in the RC IP Address Manager 3.1 Release Candidate 1 available for download


    IPAM 3.1 RC also adds support for SQL 2012 and various bug fixes.


    thanks,

    Michal

    Troubleshooting and monitoring your VoIP calls has never been easier!

     

    Today is a big day for all who were waiting for a solution that will resolve VoIP quality and connection troubleshooting problems in their business. SolarWinds has just released VoIP & Network Quality Manager 4.0! This product is an evolution of SolarWinds IPSLA Manager and it adds support for real VoIP calls troubleshooting and monitoring.

     

    If you are an existing IP SLA Manager customer under active maintenance, you can enjoy all of the new features of VNQM for no additional cost (you just need to update your license key within your customer portal. For those that would like to try out VNQM, you can download a free fully functional 30-day evaulation version. You should start your download now and in the meantime let’s take a closer look to all new features that it brings.


    Those who were watching our “What we are working on” probably know what the new features are but for the others here is a list of the new functionality:


    • VoIP calls troubleshooting based on CDR and CMR data.
    • Multi-criteria filtering/searching and sorting based on Call Details Record (CDR) and Call Management Records (CMR) data e.g. “show me calls with the same reason code, same extension pattern, same time frame, same geography or termination reason code”.
    • Automatic association of real VoIP calls with IPSLA operations in order to provide details about the call path and participating network hardware devices.
    • Added support for Cisco Call Manager version 7.x and 8.x
    • Better support for creating TCP operations in firewalled environment. This is mainly related to the case where you are trying to set up an IP SLA operation between an internal router and external device where traffic is going through a firewall.


    How to troubleshoot my VoIP?

     

    You don’t need to waste your time and collect CDR data manually from your call managers or even use non-intuitive and complicated vendor software in order to figure out where your problem is. VNQM 4.0 does everything for you! It’s a matter of few clicks to understand who was impacted by poor call quality connection or what switch or router causes problems.


    See how easy it is with VoIP & Network Quality Manager:


    Step #1 – Spend your time watching VoIP only when necessary!

     

    SummaryPage.pngAs an IT admin/VoIP Engineer you are so busy all the day so why spend your time watching for something that is not a problem?

    VNQM brings VoIP summary pages and real-time CDR based alerts in order to notify you if something bad is happening within your VoIP network.

    VNQM_4-0_AlertsVoip_Base_EN_cr.png

    Step #2 – Find exactly what are you looking for!

     

    Even if you have access to CDR/CMR data, it’s not easy to get information that would help you with a call troubleshooting. Those who have tried to do this know what I’m talking about. CDR files contain so much data and it may you take hours to find some clue that will help you. Even worse, CDR files don’t contain information about Region (location) so how do you know what sites facing troubles with calls? Does it means you need to spend hours checking logs, call managers and CDR files – especially in case when your boss says: “Fix it now!”?

     

    Well if you are using VoIP & Network quality and Manager, then NO! VNQM 4.0 provides a comprehensive VoIP search solution. You can not only search by phone extension, IP address or call time but you can also search the calls by the region they are coming out from, or going to! This is extremely useful to find a right pattern and quickly figure out what happened, when it happened, and who is impacted by this issue.

    VNQM_4-0_VoIPTroubleshooting_Base_EN.png

    In order to help you troubleshoot even more efficiently, we have pre-defined set of “Call Termination Causes” and “Redirect Reasons” so you don’t need to check Cisco admin guides to understand numeric codes!

    You can do a search for failed calls or for calls just with a call quality issue (MOS, latency, jitter or Packet Loss).


    The results of your search are displayed immediately below your search condition so no there is no “back & forth” effect when you are tracking VoIP calls issues.


    Step #3 – Fix what needs to be fixed!

     

    No “try & wait” approach! Just fix what needs to be fixed. After when you found your problematic call or pattern simply go to the call detail page and see what happened:


    callDetail.png

    Using this page you will quickly see why the call failed, what CDR qualities metrics were or what call manager was involved when connecting the call. You can also see the call signaling flow and see all participants of a particular call and see call topology (normal call, conference call, etc.).

    Now here is the great part. How do you see a call path? Easily, just create an IPSLA path operation that will be automatically displayed as part of call detail page depending on origin/destination regions. Regions are defined on call managers and VNQM offers you to pair your IPSLA capable device with CCM Region. IPSLA path operations can show you network devices that were involved in the communication between call origin and destination. It shows you network quality metrics like round trip time or latency also.

     

    Now you can drill into more details about hardware device performance, availability and quality data as well as understand if this is device that causing VoIP issues.

    IPSLAOperation.png


    As you can see, finding the switch or router that “produces choppy voice” was never easier! Now it’s just a question of a few minutes to check out this device and configure it properly. Or you can use NPM to get more details about such device.

    And by the way, unlike its previous version (IP SLA Manager), VoIP & Network Quality Manager can run either integrated to NPM or standalone.


    Once you identify network element you may use NCM to change CBQoS policies and prioritize traffic or you may use NTA and see Netflow data to block traffic that consumes too much bandwidth. Or you can just modify your routing tables and dedicate just one and best path for your site to site connection.


     

    Step #4 – Let technology work for you!

     

    OK, so now when you have fixed all the problems, how do you prevent them from happening again?

    Let’s utilize Cisco IPSLA technology and your Cisco IOS devices to produce VoIP traffic and continuously monitor your sites. This will help you to see potential problems before users start complaining. You can use VNQM alerting to send emails or SMS when you have problems.

    Stay tuned for more

    As always, WE ARE LISTENING! And I can tell you that our DEV, QA and Designers teams are already working on next most wanted and useful features of VNQM based on the RC feedback we got from our community.

    You can always share your ideas on our Thwack forum or even better – create an idea/feature request on our Ideation site. Also, you can talk to me directly!


     

    You may find the “What do you need to know about call manager” blog post useful for an even faster setup of VNQM. This article contains additional technical information about Call Managers and their configurations.


     

    Your VoIP & Network Quality Manager download should be finished so go ahead and install it. Installation will be finished in a few minutes.

     

    Thanks,

    Michal

    VoIP & Network Quality Manager 4.0 RC is out for a while and based on your RC feedback we would like to give you more details about adding Call Manager or troubleshooting possible issues during setup.

     

    First of all, your Cisco Call Manager needs to be ready for monitoring calls.

     

    You can set it up via CCM web console. To do that, please follow Cisco tutorial here: http://www.cisco.com/en/US/docs/voice_ip_comm/cucmbe/service/6_0_1/car/caranrpt.html#wp1037699

    It is usually your billing server producing CDRs and you can configure using Cisco help page: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/service/5_0_1/ccmsrva/sacdrm.html#wp1117971

    You also need to enable AXL credentials on CUCUM. That could be done easily using this tutorial: http://www.uplinx.com/cleanuptool/userguide/index.htm#page=Enable_AXL_on_CUCM.htm

     

    In case that your AXL credential test failing in VNQM add call manager wizard, you need to be sure that you can use AXL via SOAP from the VNQM web console.

    To do that type following into the browser:  https://<ip address>:8443/axl/

     

    If AXL API is working, Call Manager should see following output:

    Cisco CallManager: AXL Web Service

    The AXL Web Service is working and accepting requests. Use HTTP POST to send a request.

     

    If this is not your case, please check the VNQM to CCM connectivity (firewals, etc.) and reffer to step two – how to enable AXL credentials on CUCUM.

     

    If your Call Manager is prepared then it’s time for Adding Call Managers to VNQM:

    Navigate to VoIP & Quality Settings and click on “Add New CallManager nodes” link.

     

    help1.png

    Add Call Manager wizard appears with the list of nodes to select. Select the corresponding Call Manager node and click “Next”.

    help2.png

    After clicking “Next”, a new screen appears asking what needs to be monitored for the Call Manager node. The Call Manager node can be added with or without CDR/CMR polling.

     

    If you can’t add a node that is supposed to be a call manager then you have probably SNMP service turned off on Call Manager. Take a look on the following screen which shows you how to find if SNMP is turned ON.

    help3.png

    Note:  If added with CDR/CMR polling, the wizard gives an option to enter AXL credentials (to poll region specific data) and FTP server credentials (where the CDR/CMR files are stored).

     

    help4.png

    Click “Next” after selecting the monitor type.

     

    Note: If without CDR/CMR monitoring is selected, the wizard adds the call manager without providing an option to enter AXL credentials and FTP credentials. It can be added later by editing the call manager node

     

    help5.png

     

    1. Click on the “What are AXL Credentials” link to know more about AXL. Enter the AXL credentials.
    2. Click “Test” button to test the AXL credentials.

     

    Click “Next” button to continue.

    Add FTP Server (where CDR files will be placed):

    help6.png

    1. If the FTP server IP entered is a SFTP server, secure connection check box should be enabled to continue.
    2. The FTP folder name where the CDR/CMR files are stored.
    3. Click on the Test FTP server connection to check if the entered credentials are valid.
    4. The polling frequency is defaulted to 1 minute and can be changed to any value from 1 to 60.
    5. Enabling the Delete check box will delete all the CDR/CMR files from the FTP server once the polling is complete.  To know more about this feature, click on the “Why would I do this?” link.

     

    After clicking on “Next” button from the Add FTP server page, the final summary page appears. Users can review the entered data and clicking on “Add Call Manager” adds the call manager to the VNQM.

     

    Now you are eligible to do a search for CDRs via VNQM web console and system will periodically poll for new CDR files.
