Healthchecks

Healthchecks

Monitor cron jobs and background tasks by pinging unique URLs. Get alerts for missed runs, failures, and long runtimes via email, SMS, and popular integrations.

Healthchecks screenshot

Healthchecks is a cron job and background task monitoring service built around simple “ping” URLs. You add a check, instrument your job to call the provided endpoint, and Healthchecks tracks schedules, runtimes, and failures to alert you when something goes wrong.

Key Features

  • Ping-based monitoring for cron jobs, one-off scripts, and background workers (success, fail, and start signals)
  • Flexible scheduling (period/grace time) with detection of missed runs and late jobs
  • Status signals: success, failure, and “start” to detect long-running/hung tasks
  • Notification channels including email and multiple third-party integrations (webhooks and chat/incident tools)
  • Teams and projects with role-based access for multi-user setups
  • Maintenance periods / downtime handling and per-check pause controls
  • Check-level API and management UI for creating and maintaining checks
  • Timezone-aware reporting and history of pings/runs for troubleshooting

Use Cases

  • Alert when backups, database maintenance, or ETL pipelines don’t run on schedule
  • Track long-running batch jobs and detect hangs using “start” + timeout
  • Monitor periodic health tasks in container/Kubernetes environments via HTTP pings

Limitations and Considerations

  • Healthchecks monitors scheduled execution via pings; it is not a full infrastructure/metrics APM system.

Healthchecks is a lightweight, reliable way to get notified about missed or failed scheduled jobs without deploying a full monitoring stack. It works well for ops teams and developers who want simple instrumentation, clear run history, and flexible alert routing.
