SILENS

Dead man's switch for scheduled jobs

Know the moment a job goes quiet.

Your backup, cron job or batch pings Silens when it finishes. Miss a ping — or send a bad result — and you hear about it. The alarm fires on the signal that didn't arrive.

The trace is the healthy job. The flatline is what Silens is built to catch.

Why it's not just another cron ping

Verify the result, not just the run Send a number with your ping — row count, backup size, record age — and Silens alarms if it drifts out of the range you set. Catches the "backup ran but produced a 0-byte file" case.
Duration anomaly detection Silens learns how long a job normally takes and warns when a run suddenly takes far longer — an early signal before it fully fails.
Windows-first, not just cron Every check gives you a ready-to-paste snippet for Task Scheduler (PowerShell), cron, Python and curl. No translation needed.
