script to check cron jobs

LYC · 08-28-2015, 03:29 AM

Hi,

What to lookup to verify a cron job has run successfully and failed if a script is to be written?

Thanks in advance.

usually the job has its own log, you need to check it

Hi,

Due to my limited knowledge, I can only find the cron log in /var/log/cron. There is a single line that indicating the status of the job but needs to be interpreted. There is also no info on how long the cron job has been run.

I mean the job itself should write its own logfile, it is not about the log of cron. If your job has no such functionality you can add a wrapper script like this to do that:

Code:

LOGFILE=<this is the name/path of the logfile>
echo "starting job JOBNAME" >> $LOGFILE
date >> $LOGFILE
<execute the original job>
echo "job completed"
date >> $LOGFILE

Hi,

Correct me that there is no centralised mechanism to track?

Each user has to be responsible to track their cron job?

cron itself does not take care about the jobs executed.
but may send email about execution

Hi,

Could you advise how to configure cron to send out mail about execution?
