Nmon Analysis

Dear All,

I am an performance tester. Now i am working in project where we are using linux 2.6.32. Now I got an oppurtunity to learn the monitoring the server. As part of this task i need to do analysis of the Nmon report. I was completely blank in this.
So please suggest me how to start learning the Nmon report analysis.
Share your valueable ideas on this.
Thank you so much in advance.

Thanks & Regards,
Sengu.
