More details in server performance health check blog. To measure against QM server, best to add the widget from a QM dashboard, and select it from the QM server catalog.
Checking performance can be difficult. The base thing to do is to set up some "synthetic" user transactions, run them every 5 or 10 minutes, and time how long they take to execute. The best metric to capture is end user performance, and if you write a small script to just continually check the end user performance, it will give you an idea of the type of performance that you are seeing.
I plan on releasing a whitepaper on this out on my blog later this week. It is going through a technical review right now.
