This script logs CPU load for a given process, every n seconds into a file
Requires : bash, ps, awk
Examples :
psmon <process name> [delay [logfile]]
psmon sshd→ logs %CPU load from process sshd, every 5 seconds, to file psmon.log.[day]
psmon q3ded 10 q3ded.log → logs %CPU load from process q3ded, every 10 seconds, to file q3ded.log
CODE:
-
#!/bin/bash
-
-
if [ -z $1 ] ; then
-
echo "Monitor a cpu load for a given process, every n seconds"
-
echo "Usage : `basename $0` <process name> [delay [logfile]]"
-
echo " [delay] : defaults to 5 seconds"
-
echo " [logfile] : defaults to psmon.log.yymmdd.hhmmss"
-
echo " if you specify a logfile, you MUST specify a delay"
-
echo "Example : psmon q3ded 10 q3dedmonitor.log"
-
echo "Example : psmon q3ded"
-
exit 0
