How to tell how many cron jobs are in the queue

[James Brand]

We'd like to monitor the number of cron jobs in the queue but don't know how to check.

We recently had a problem when a script that runs every few minutes failed to complete and filled up the queue. The script has logic to make sure this won't happen but apparently didn't work. That's being fixed but we'd also like to set up a Tivoli alert.

Does anyone know how to check the number of cron entries in the queue? (I've already changed /var/adm/cron/queuedefs)

Thanks,
Jim

"ps -ef|grep pidofcron" will show u the currently asscoaited cron jobs

Also u may put some thing similar condition in script

cat /var/adm/cron/log|tail -100|grep "MAXRUN" >/dev/null 2>&1
if [ $? -eq 0 ]
then
echo "PLease check cron jobs"
fi

you also might want to look at queuedefs
it's the queue description file for at, batch, and crontab.

at -l
and
crontab -l

??

Maybe you could monitor the size of /var/adm/cron/FIFO?

I'll write a script to grep for number of cron processes running.

Thanks!
