I don't want the list of all process, just a total percentage like you would see in windows taskmanager. 

I will be using this information via coldfusion, but i am having all kinds of problems just trying to find a total number of current cpu usage. 

I don't care if it comes from wmi or t-sql, i just want a total number for which i will be using to populate a gauge chart that via ajax will be showing my current cpu usage percentage...

Thank You...
