Healthchecks.io is a monitoring service for your cron jobs. With Healthchecks monitoring, you will get notified just minutes after your cron job fails to complete on time.
Setting up the monitoring for your cron jobs only takes minutes. For each monitored cron job, Healthchecks.io creates a unique ping URL. Edit each cron job to send a HTTP request to its ping URL just before the job finishes. Healthchecks.io keeps track of the received pings, and sends alerts as soon as any of your cron jobs does not check in at the expected time.
