Quick answer
Public sites give errors, but background scripts fail silently. How agentless heartbeats catch broken database backups.
The Illusion of Automation
You wrote a bash script to back up your PostgreSQL database every night at 2 AM. You set up the Cron job, checked it once, and forgot about it. Six months later, a server crashes. You go to restore the database, only to find the backups stopped working four months ago due to a full disk. This happens more often than anyone admits.
The Agentless Heartbeat Solution
Installing heavy monitoring agents on your private servers is a security nightmare. The fix is much simpler: passive webhook heartbeats. The monitoring platform gives you a unique URL. You just add curl https://pingstag... to the very end of your backup script.
Detecting the Silence
Now, every time the script finishes successfully, it knocks on our door. If we expect a knock every 24 hours and hear nothing, the system instantly flags it. No agents, no complex setup. Just a simple safety net for the scripts you forget about.
