Alerting on a failed cron job

Question

Is there anyway to alert on a cron job that may have failed to execute for whatever reason on a CentOS 7 EC2 instance? I'm looking for a tool or to review a process that anyone else might be using for something like this.

There is a good answer to your question here: https://unix.stackexchange.com/questions/314640/how-to-make-cron-send-email-with-error-log-when-script-throws-errors

In summary it says:

20 6-10 * * 1-5 ~/job_failure_test.sh > ~/job_fail.log 2>&1 || mail -s "Errors" [email protected] < ~/job_fail.log

But follow the link to the question as there is some good pointers there.
