cron job

hi,
how i woulsd be able to find that my cron job is running or not..
E.g abc

just type this

ps -ef | grep cron

inside my root crontab
30 3 * * * [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean

To check if the cron is running or not.

vi /var/cron/log

I have an entry that show matching time at 3:30am

> CMD: [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean
> root 13382 c Thu May 8 03:30:00 2008
< root 13382 c Thu May 8 03:30:00 2008

it's running.
