You have a System Center Operations Manager 2007 environment. You need to automatically restart the Internet Information Services (IIS) service when the %Processor Time counter is at or above 90 percent for more than 5 minutes. What should you do?
A.
Create a Consecutive Samples Over Time monitor for the %Processor Time counter. Add an agent task to restart the IIS service.
B.
Create a Consecutive Samples Over Time monitor for the %Processor Time counter. Add a recovery task to restart the IIS service.
C.
Create a Windows performance rule for the %Processor Time counter. Add an agent task to restart the IIS service.
D.
Create a Windows performance rule for the %Processor Time counter. Add a recovery task to restart the IIS service.
Explanation:
B: CORRECT
Consecutive Samples Over Threshold – This type of monitor alleviates some of the false positives that you may obtain when using a simple threshold. Simple thresholds only monitor when an object exceeds a limit, but do not take into account those objects that may spike periodically.
Processor utilization and network utilization are good examples of this. There may be short bursts of network activity, or the processor might be momentarily taxed, but they quickly return to normal activity. The consecutive samples over threshold will not change its state until several samples have been taken that indicate the object is still over the threshold value. For this type of threshold, you must specify the warning or error level that you are watching for, as well as the number of samples that must be taken that show the threshold being exceeded.
