What should you do?

You have a System Center Operations Manager 2007 environment. You are creating a Windows Performance Counters monitor for % Processor Time. You need to be able to select the All instances option when you create this monitor. What should you do?

A.
Create an aggregated rollup monitor.

B.
Create a dependency rollup monitor.

C.
Create a static threshold monitor.

D.
Create a self-tuning threshold monitor.

Explanation:
C: CORRECT
Static threshold monitors are used to make sure that an object does not fall outside of safe parameters.
Of course, you have to know which limits you are watching for. Some are well documented; others you will have to glean from a baseline of your system. Once you have determined what the peak value is, you can create a static threshold monitor. During the schedule that you set, the agent will watch for the system to exceed the threshold, and an alert or health state can be modified.
