Healthchecks on Ubuntu 24.04 LTS

Overview

Healthchecks is an open source, self hosted monitoring service for cron jobs and scheduled tasks, a dead man's switch for the jobs that run in the background where nobody is watching. Every job, backup, certificate renewal or batch process gets its own unique ping URL and requests it when it finishes; if a ping does not arrive on schedule, Healthchecks marks the check late or down and notifies you through email, chat and dozens of other integrations. Unlike active probing that watches a service from the outside, this passive model catches the jobs that silently stopped running.

It suits anyone who runs scheduled work they cannot afford to fail quietly, from a single backup script to hundreds of pipelines across a fleet, and who would rather own their monitoring than send job execution details to a hosted service.

Common uses

• Alerting when a cron job, backup or batch task silently stops running
• A private self hosted alternative to hosted cron monitoring services
• Watching scheduled pipelines and certificate renewals across a fleet
