Cron job monitoring alternative to Dead Man's Snitch
Scheduled jobs fail quietly more often than most teams expect. A process exits early, a server misses a window, credentials expire, or the scheduler stops entirely.
Without heartbeat monitoring, failures are discovered late from stale data or user reports. Reliable check-ins and overdue alerts close that blind spot.
Quickstart
Monitor your first cron job in under 5 minutes
- Create an observer and copy the check-in URL.
- Paste the check-in call after the job completes.
- Set schedule + grace period. That's it.
#!/bin/bash # reports.sh && heartbeat reports.sh && curl -fsS -X POST https://cronobserver.com/checkin/<token>
Replace <token> with the observer token provided in the dashboard.
How CronObserver works
1) Add a heartbeat ping to your job
Add one HTTP check-in call after successful execution of your cron task.
2) CronObserver expects it on schedule
Define schedule and grace period so brief delays do not cause unnecessary noise.
3) Missing or late runs trigger alerts
If the heartbeat is late or absent, you are alerted quickly through configured channels.

CronObserver vs Dead Man's Snitch
What is Dead Man's Snitch?
Dead Man's Snitch is a cron job monitoring service based on heartbeats. Each scheduled job sends a check-in, and missing or late check-ins trigger alerts.
CronObserver uses the same general model: jobs send check-ins, and overdue runs are detected against schedule and grace period settings.

Dead Man's Snitch alternative FAQ
Is CronObserver a Dead Man's Snitch alternative?
Yes. CronObserver is a heartbeat monitoring tool for scheduled jobs. You add a check-in call to your cron job, and CronObserver alerts you when a run is missing or late.
How does heartbeat monitoring work?
Each job sends a ping (check-in) after it completes. CronObserver tracks the expected schedule and grace period; if a check-in does not arrive on time, an alert is triggered.
What happens if my server is down?
If your server cannot execute the job, the expected check-in is missed. CronObserver marks the observer as overdue and sends alerts based on your configured escalation channels.
Can I monitor multiple jobs?
Yes. You can create multiple observers and assign one check-in token per job. Plans define how many observers you can monitor.
Does it work with Docker and Kubernetes?
Yes. Any environment that can make an HTTP request works, including cron on Linux, containers, Kubernetes CronJobs, CI pipelines, and serverless jobs.
Can I get alerts to email, Slack, webhooks, or Microsoft Teams?
CronObserver supports alert delivery via email or one webhook channel. On the free plan, each observer includes one alert channel (email or webhook). Webhook URLs can be used for Slack or Microsoft Teams.
How long does it take to set up?
Most teams can set up their first monitor in a few minutes: create an observer, copy the check-in URL, and call it at the end of your job.
Is there a free plan or trial?
CronObserver offers a free plan. You can start without a credit card and upgrade later if you need more observers or advanced capabilities.
