A plugin to check long running processes on Linux.

IMPORTANT: This script checks elapsed CPU time not elapsed run time.
This script will take multiple arguments and alert if a process has consumed more than x number of CPU days e.g:

$ check_long_running_procs.sh -w 10 -c 20
LONG RUNNING PROCESSES WARNING: there is/are 1 long running processes on `hostname`
WARNING PID 950 () from user has used 12 CPU days and has run for a total of 13 days

The script has an optional space seperated exclude list e.g

$ check_long_running_procs.sh -w 10 -c 20 -E "sge pdflush"

The script also has a hidden function which can email a user with a warning message informing them of their long running process. You can enable this by using the “-e” flag followed by your username. You will also need to set the “DOMAIN” variable to your domain name. This function assumes your email address is @ if not you might need to recode a little.

IMPORTANT: This script checks elapsed CPU time not elapsed run time. However it would be pretty easy to recode the check to report on total run time rather than CPU time.
