Fetching CPU usage and memory leak from the server

Question

How do I get CPU performance with JMETER.

My environment:

apache-jmeter-2.9
ServerAgent-2.2.1
Windows Server 2008 R2

The problem is, when the I run the server agent in the server and trying to fetch the data in jmeter UI the command prompt on the server shows error :
