Know when your background jobs fail silently
Your job pings SignalDocks when it completes. If no ping arrives on time, you get alerted — catching silent failures before they cause data problems.
Free plan available · No credit card required
Heartbeat-based detection
No polling needed on our end. Your job sends a GET ping to a unique URL — if it doesn't arrive, the alert fires.
Configurable grace period
Set how many minutes after the deadline before an alert fires. Handle slow jobs without noisy false positives.
Start & fail signals
Optionally ping /start when your job begins and /fail on error. SignalDocks measures job duration and catches explicit failures.
How it works
Up and running in minutes
Create a cron monitor
Set the expected interval (e.g. 60 min) and a grace period. Copy the ping URL from the monitor detail page.
Add the ping to your job
One curl command at the end of your script — or a fetch() call in Node. No SDK or dependency needed.
# Add to the end of your job
curl -fsS "https://signaldocks.com/api/ping/YOUR_KEY"
# Node.js
await fetch("https://signaldocks.com/api/ping/YOUR_KEY")Get alerted on missed pings
If the ping doesn't arrive within interval + grace period, an incident opens and your team is notified.
