Crontab's log is relatively simple, and when crond fails to perform a task, it will send an email to the user. It happened that a task did not execute properly on one of our servers, and crond email failed. By looking at mail's log, I can see that it is caused by a lack of disk space.

In addition, my colleague helped me to add my own log for the tasks in crontab, so that it was easier to see the reason after making an error.

0 6 * $HOME/for_crontab/createTomorrowTables > > $HOME/for_crontab/mylog.log 2 > & 1

Output both error output and standard output to mylog.log.

Note: do not write as

0 6 * $HOME/for_crontab/createTomorrowTables 2 > & 1 > > $HOME/for_crontab/mylog.log
