A simple script may be used to look for active servers and their CPU usage. The fact that each server runs its 'own' fatsrv module is used by this script, which reduces to three lines:
fatps
echo 'FATMEN server Elapsed CPU time %CPU' echo '===============================================================================' ps -aef -F "args,etime,time,pcpu" | grep "/fatsrv" | sort +2 -r
One may also inspect the log files, e.g. tail -f fatserv.log.
