We are happy to announce the release of SolarWinds® Traceroute NG, a standalone free tool that finds network paths and measures their performance.

The original traceroute is one of the world’s most popular network troubleshooting tools but it works poorly in today’s networks. You can read about its shortfalls in this whitepaper.

SolarWinds® fixed these shortfalls with NetPath, a feature of NPM.  People love NetPath but there are two problems.  First, NetPath takes a couple minutes to find all possible paths in complex networks, much longer than a quick tool like traditional traceroute. Second, most people don’t own SolarWinds® NPM and so don’t have access to NetPath.

Traceroute is too important of a tool to allow it to languish.  That’s why we’ve taken what we’ve learned with NetPath and fixed traceroute.  We call it Traceroute NG.

Traceroute NG is a super fast way to get accurate performance results for a network path in a text format that’s easy to share.

Compared to traceroute, TracerouteNG is:

  • Super-fast
  • Rarely blocked by firewalls
  • More accurate, thanks to path control
  • Updates latency/loss continuously
  • Detects path changes
  • TCP or ICMP

 

You can download Traceroute NG here and launch the tool by double-clicking the traceng.exe.

You’ll be presented with a help screen and the application will wait for your input. Type the domain name to start a trace.

 

You can also launch the free tool from Windows command prompt:

traceng www.google.com

Let’s look at some results.

 

Scenario 1: Endpoint is blocking TCP port

We all know that HTTP uses TCP 80 by default. What would traceroute show you if someone blocks that port on a firewall or webserver?

All good, it’s not the network. You know it’s not your issue. But what is the issue?  That’s where Traceroute NG will help:

Traceroute NG can mimic TCP application traffic, so packets are treated as the application traffic is. In this case it detected that port TCP 80 on the destination webserver is closed. You know, it’s not the network. But you can be more precise and tell your sysadmin to enable this port on his webserver.

 

Scenario #2: Network path change

To illustrate this scenario, I have created a simple network using GNS3.

 

I also have a loopback adapter configured, to point all IPv6 traffic to this lab:

 

I’d like to trace from my machine in Cloud1 to the PC (fc90::3). If the OSPF routing works, I should go through routers R1, R7 and R3. Traceroute confirms:

 

Traceroute NG as well:

 

What if I do maintenance on router R7? Will traceroute tell me, when router R7 becomes unavailable and detect the new path? No. It runs once and then you need to run it again. Manually.

With Traceroute NG, detecting a change is simple. You can tell Traceroute NG to warn you if the path changes and optionally log the output. An example command would be: -a warn -l -p 23 fc90::3

And this is the result:

 

So you know that your router is down and once you hit enter, Traceroute NG will show you the new path. In the GNS3 lab we expect the new path will go through R1, R5, R2 and R3. Traceroute NG confirms:

 

And the log file as well, showing you original path and the new path:

In this use case, we have leveraged several features of Traceroute NG. First, it runs continuously. Second, it detects, when a path is no longer available. Third, it can log results in a text format, that’s easy to share.

Now, enough boring reading, it’s time to try it out! You can download Traceroute NG here: https://www.solarwinds.com/free-tools/traceroute-ng/

 

We’re super excited to share this tool with the world and hope you find it useful.  Let us know your thoughts!

We’re happy to announce the release of SolarWinds® Storage Performance Monitor, a standalone free tool that provides a consolidated view of all your storage array’s performance.

We are excited to share, that we've reached GA for Web Help Deskv12.5.2

 

This service release includes:

 

Clickjacking protection

This release prevents malicious code from redirecting a hyperlink in the Web Help Desk user interface to an unauthorized third-party website or resource.

 

Secure password reset logic

After you click Forgot Password on the Log In screen, Web Help Desk verifies your current email address and redirects you back to the application using a secure connection to reset your password.

 

Improved LDAP security

Web Help Desk now prevents unauthorized LDAP client account users from logging in to an LDAP tech account with an identical user name. In v12.5.1 and earlier, WHD had 2 ways to handle LDAP authentication. One for techs and one for clients. After you install this release, the tech LDAP authentication functionality is removed, and every tech, who used this functionality will have his WHD password reset, and will also receive an email with steps to log in to WHD.

See Unauthorized clients can log in to a Tech account using LDAP authentication for details.

Before you install this upgrade, ensure that all techs have client accounts (authenticated through LDAP) linked to their tech accounts. Also ensure, that the tech username is not the same as any of the client's usernames. After the upgrade, all techs must access their tech account through their client account, or using the WHD tech username and WHD password (which can be reset using the secure password reset logic).

 

Updated Apache Tomcat

This release supports Apache® Tomcat® 7.0.82 for improved security. See the Apache Tomcat website for details.

 

Notabe fixed issues

Tickets linked to a survey now close properly after you change the status to Resolved.

The Office 365 connector now supports subfolders.

Tickets restricted to a location group can no longer be accessed by users in another location group.

 

We encourage all customers to upgrade to this latest release which is available within your customer portal.

Thank you!

We’re happy to announce the release of SolarWinds® Exchange Monitor, a standalone free tool that provides a view of your Microsoft® Exchange Server performance.

Exchange Monitor gives your team insight into metrics, services and Database Availability Group (DAG) status. This tool supports Exchange Server 2013 and 2016.

 

Metrics monitored by Exchange Monitor:

  • Total Service IOPS (count)
  • Host Used CPU (%)
  • Host Used Disk (%)
  • Host Used Memory (%)
  • I/O Log Writes Average Latency (ms)
  • I/O Log Reads Average Latency (ms)
  • I/O Database Writes Average Latency (ms)
  • I/O Database Reads Average Latency (ms)
  • Outstanding RPC Requests (count)
  • RPC Requests Failed (%)

Services monitored by Exchange Monitor:

  • Active Directory Topology
  • DAG Management
  • Exchange Replication
  • Information Store
  • Mailbox Assistants
  • Mailbox Replication
  • Mailbox Transport Delivery
  • Mailbox Transport Submission
  • Search
  • Service Host
  • Transport
  • Unified Messaging

DAG info:

  • Databases (count)
  • Current Size (GB)
  • Total DB Copies (count)
  • Disk Free Space (GB)
  • List of servers belonging to the DAG and their health status

 

 

Exchange Monitor gives you the ability to add as many Exchange Servers as you wish. Simply click the “Add Server” button and fill IP address/domain name and credentials. The only limitation when adding a new server is, that you cannot add 2 servers from the same DAG. Monitoring multiple servers from the same DAG can be achieved only with Server & Application Monitor (SAM).

Once you add a server to Exchange Monitor, it will load polling interval, metrics with thresholds and services to monitor from global settings. You can edit these settings locally – per server. When looking at server details page, click the COMMANDS button in the top – right corner and select “Manage Metrics”.

 

You can then fine-tune your thresholds for this server only. Here you can also turn off metric, if you do not wish to monitor it. When you do not monitor a metric, you will not get any notifications about this metric.

 

If an Exchange Server belongs to DAG, you’ll see Database Availability Group (DAG) resource on the server details screen. Bottom part of this resource contains information about all servers belonging to this DAG and their health status. You can inspect status of these servers by clicking on “Show All” button.

 

Hovering over these servers will give you additional information about Content Index State and Copy status of the databases assigned to this server.

 

 

 

What else does Exchange Monitor do?

  • Allows you to add as many Exchange servers as you wish (with limitation to monitor only 1 server per DAG)
  • Creates notification every time, when metric goes over threshold, service goes into non-running state or DAG is not healthy

       

 

  • Can write all notifications into Event Log.
  • Allows you to set your polling interval (how frequently you want to receive data from Exchange Server) per server
  • Allows you to set thresholds, metrics to monitor and services to monitor per server

OpsGenie – a cloud based alert and notification management solution – has recently announced integration with SolarWinds Web Help Desk. So, how does it work?

  1. WHD sends an email to OpsGenie, which in turn creates a new alert in OpsGenie.
  2. OpsGenie then sends alert actions back to WHD via Web Help Desk API. OpsGenie can make a web request to the WHD and update the ticket with a note. WHD needs to have a web-based URL that is accessible from the internet (http://hostname:port).

WHD-OpsGenie.jpg

 

By using OpsGenie with SolarWinds Web Help Desk Integration, you can forward SolarWinds Web Help Desk tickets to OpsGenie. OpsGenie can then determine the right people to notify, based on on-call schedules, email, text messages (SMS), phone calls and iOS & Android push notifications. OpsGenie will continue to escalate the alert until it’s acknowledged or closed.
