Healthchecks.io is a service for monitoring your cron jobs, batch jobs, scheduled tasks, backup scripts etc. It is available in a hosted form on https://healthchecks.io, or you can self-host it, the code is BSD licenced and development is done in the open: https://github.com/healthchecks/...
The hosted version offers a generous free plan, with monitoring of 20 services included, and up to 3 team members. The paid plans are reasonably priced and lift the limits significantly.
If you are a developer, devops engineer or systems administrator looking after various small services, and have had a nagging thought "if this randomly breaks six months from now, I wonder how soon someone will notice", then this is for you!
