Monitoring Citrix Netscaler Load Balancers with SCOM 2007 R2 Part III.

In Citrix, Netscaler, Operations Manager on October 21, 2011 at 20:28

This is part three of my series on monitoring Citrix Netscalers with SCOM 2007 R2 ( Part I and Part II).

Now, does it work? And how? As said in my previous post the way the information is presented is a little bit different then with other MP’s. For each SNMP trap sent the pack will raise an alert – and the alert will tell nothing more then the fact that the SNMP trap has been sent đŸ˜‰ If you make a config change you’ll get an alert that it has been changed..but not what has been changed. That information is shown elsewhere.

To give an example, in the picture below you can see two alerts:

I changed the configuration and saved the running config. This is the information as shown in the config change alert:

To see what has been changed we need to head over to the Events node, here two events are shown:

If you look at the details of the event we can see that a SNMP community reference was added to the Netscalers with “public” as a community string:

Then there is the Health Roll-up of the entity. The health monitored health categories are Availability and Performance. Performance is  based on some SNMP GET based performance metrics of both the appliance and the vservers. Availability is based on the state of the appliance alone and so if a vserver is down the Netscaler Device entity will still be healthy.

And last but not least – the Netscalers themselves also allow you to tune what SCOM will report because you can enable/disable and configure its SNMP traps. You can do this from the GUI by opening System\SNMP\Alarms.

Depending on the type of alarm you can define the alarm and normal thresholds, the time interval and the alarm’s severity. Whatever you configure here will direct influence the way SCOM will report about these events. Of course its also possible to override the rules and or alerts in SCOM but personally I prefer to do this at the source.

I hope this guide will help others to get this MP running in their environment and possibly even convince others to choose this method of monitoring Netscalers.

  2. Thanks! Very helpful

  3. Thanks for a good guide on monitoring Netscaler using SCOM. Not easy to find information on the subject and the documentation that come from Citrix is, as usual, not as good as you’d hope.
    Have you been able to get the status of individual vservers using scom?
    I’m looking into getting a full status view of our XenApp setup using SCOM and getting the status of the vservers used to loadbalance the WI and XML services in that wiev would be nice.

    • Good to hear you found it to be useful. Atm I just have the state of the vservers as a performance view (the built in one) but I can give it a go to create a monitor and associated view.

  4. Excellent documentation.
    Our NetScaler is on Linux, do we need the account set somewhere… ? Device States are in SCOM, Perfromances are in SCOM but Events is always empty??
    Thanks,
    Dom

  5. great article, very informational.
