Which performance counter should you use?

You are the systems administrator for your organization. Your network runs Windows Essential Business Server 2008. You install System Center Essentials 2007 on a server in the network, named SCE1. You create several application packages on SCE1 to deploy these applications to managed computers on the network.

You deploy a software package to a test computer to verify the application’s response time. You start the Reliability and Performance Monitor to determine the response time of an application.

Which performance counter should you use?

A.
Memory: Hard Faults/min

B.
Memory: Working set (KB)

C.
Memory: Shareable (KB)

D.
Processor: % Processor Time

Explanation:
You should use the Memory: Hard Faults/min counter. The Memory: Hard Faults/min performance counter shows the number of hard faults per minute currently resulting from the application instance. A hard fault is not an error. It occurs when the page of the referenced address is no longer in physical memory. You can determine the response time of an application from the number of hard faults in the Memory: Hard Faults/min performance counter.

All other options are incorrect because you cannot use them to determine the response time of an application.

The Memory: Working set (KB) performance counter determines the number of kilobytes currently resident in memory for the application instance.

The Memory: Shareable (KB) performance counter determines the number of kilobytes of the application instance’s working set that may be available for other applications to use.

The Processor: % Processor Time counter reports the percentage of processor time being used. You should upgrade to a faster processor or install an additional processor if the Processor% Processor Time counter reports threshold percentages above 85%. You can configure an alert to be notified when the processor utilization reaches the specified threshold.
