Thank You for Your response. You helped me a lot!!
[root at va2005 vu2328]# rrdtool fetch vmstat.rrd AVERAGE --start 1387015833 --end 1387188633 |tail | awk '{print $17}' |awk '{printf "%.2f\n", $1}' 98.67 99.00 98.83 99.00 99.00 99.00 99.00 99.00 98.67
Now I substract this number from 100 and it works great! Awesome!

<CPU Utilization graph>
Could You tell me how to get the values of the "% CPU Busy" listed on the bottom ? I have tried a lot of things but it doesn't work
The "CPU Utilization" graph with "CPU busy" is defined in graphs.cfg in the [la1] section. This shows that the data source is "cpu_idl" in the vmstat.rrd file. Note that the graph definition subtracts this "cpu_idl" (idle percentage) number from 100 to get the busy percentage.
You can get the last few entries of cpu_idl by running: rrdtool fetch /path/to/vmstat.rrd AVERAGE | tail The contents of the RRD file come from the [vmstat] section of the client data messages. This is typically taken from the output of "vmstat" from the idle column (normally abbreviated "id"). To get the average idle percentage over 5 minutes, Xymon runs "vmstat 300 2". If you want to get the idle percentage without waiting 5 minutes, you can type "vmstat 5" and it will repeatedly give 5-second averages forever. Note that the first line in the vmstat output is the average of the metrics since last boot. Cheers Jeremy
