Monitoring a drop in CPU usage
This maybe the wrong place for this and if so I apologise. I need to monitor a few systems for a sudden drop in CPU usage. They are normally peg at 80% and it will drop to zero when the application running on them crashes. The app does not write anything
to any event log so I was going to try and setup something to let me know when the CPU usage dropped to or below 15%. Is that possible?
Thanks,
David

Hi
You can create a Unit Monitor based on a Windows Performance Counter, with a single threshold and you have options for:
- delta threshold (changes by more than 50%)
- Simple Threshold - threshold 15% - above 15% healthy. below 15% = unhealthy.
This is all doable in the GUI - authoring, management pack objects, monitors
Make sure you save to a custom management pack.
Also, target the most granular operating system when it asks for a target. E.g. Windows 2008 Operating System. Best practice would be to create seperate monitors for each operating system if the systems cover multiple apps.

Thank you both but I have another question. This looks like it will do what I want it to but the application I am trying to monitor is only on 10 machines. I have them in a group I created but I cannot choose it when I set this up. I have to pick one of
the predefined groups in SCOM. Is there a way around that or a better way to do it?
Thanks for your help

Just to make sure:
1) Create the monitor disabled targetted at Windows operating system
2) Set an override (enable = true) saved to a custom management pack for the monitor against the group.
