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. http://systemcentersolutions.wordpress.com/category/concepts/targetting-rules-and-monitors/ Cheers GrahamView OpsMgr tips and tricks at http://systemcentersolutions.wordpress.com/

Additionally, I would like to share the following with you for your reference: How to Create a Static Threshold Monitor in Operations Manager 2007 http://technet.microsoft.com/en-us/library/bb309655.aspx Hope this helps.

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

Sorry guys but I think I answered my own question. I will let you know the outcome.

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. Cheers GrahamView OpsMgr tips and tricks at http://systemcentersolutions.wordpress.com/
