assuming you are using linux (or SysV *nix) then : ps h -C MyProcessName -o "%cpu" will give you the amount of cpu consumed by the process named "MyProcessName" which then you need to send out as a metric (in this example called "MyProcessCPU") with something like : gmetric --name=MyProcessCPU --value="`ps h -C MyProcessName -o "%cpu"`" --type=float --units="%" which then will need to be scheduled every minute through crontab by doing : echo '* * * * * gmetric --name=MyProcessCPU --value="`ps h -C MyProcessName -o "%cpu"`" --type=float --units="%"' >> /etc/crontab > For example, > I would like to store lastest 100 sample CPU usage of a specific > process for further processing, in the host that run gmond. What > should I do? if you want to "store" a limited number of samples, then you probably just want to write them to a file and rotate that instead of using gmetric and extracting them later from ganglia. ganglia (through gmetad) uses RRD files for storage which allow for unlimited number of samples in a concise format but that is not meant to be accurate as it averages over time.
