Healthchecks.io: Cron Job Monitoring
Get instant alerts when your cron jobs, background workers, scheduled tasks don't run on time. Monitor up to 20 cron jobs for free.
Categories:
Healthchecks.io is a simple and effective cron job monitoring service that notifies you when scheduled tasks like nightly backups, reports, and background jobs fail to run on time.
π Overview
Healthchecks.io is a cron job and background task monitoring service using a "dead man's switch" approach. Your jobs send periodic HTTP pings or emails to the service. If a ping doesn't arrive within the expected period plus grace time, it triggers alerts via numerous integrations.
It solves the critical problem of cron jobs and scheduled tasks failing silently, which can lead to undetected issues like missed backups or unreported data until much later.
Built for developers, DevOps teams, sysadmins, and anyone running periodic tasks on servers, containers, Kubernetes, or cloud schedulers. PΔteris Caune created it in 2015 in Latvia to provide reliable, privacy-focused monitoring with clean UI, focusing on user happiness and simplicity.
The service is hosted on Hetzner bare metal with >99.9% uptime, but the full source is open-source for self-hosting.
