CPU, Disk and memory message format to obtain valuable Graphs

Hello,

 
I am developing another windows client based on the nagios nrpe plugin.

The script is based on the checkwin monitor that you can find in
http://code.google.com/p/checkwin/

Tests are going well but I have a problem with the graphs that are
generated for the disks, cpu and memory values.

Can anyone help me with the format that I have to send to the xymon
server?

I don't know on which parameters the rrd files are generated for these
particular tests.

 
Thanks in advance
