HI I�m new on this world.
I�m working with nmon and I understand that this tool generates a files that later with excel I can see the graphcial of my server.
The problem is that this process is execute manualy and I need to meake automatic.
How can I do That.
Sorry for my english!! :o
Add a crontab line, then. 
You can put nmon into "daemon mode" where it takes a snapshot at regular intervals for a certain amount of cycles. This line you can put into crontab.
Consult the man page and the online help of nmon (which is quite extensive) to find out how.
