How to watch jobs you already run. Each page is written for a search, not a product tour. For the API, Slack, Discord, and JSON payloads, see Docs.
Get alerted if a cron job didn't run
Heartbeat after a successful cron. Silence is the Down alert.
Know if a nightly backup never finished
Ping after a successful dump or sync. A quiet night is the failure.
Alert if a GitHub Action never ran
Install gonewatch/heartbeat@v1. Catch a scheduled workflow that never ran.
