- By default, we aren’t alerted when a cron job fails. We can use a 3rd party tools like Cronitor to get notified via emails when the cron job fails. Cronitor provides great visibility into the cron job by installing an agent alongside the cron job, so we are able to obtain error logs of cron jobs too!
