Heartbeat monitoring
Heartbeat monitoring expects a scheduled job to check in, and alerts you when the expected ping doesn't arrive.
Also called a dead man's switch, heartbeat monitoring is the inverse of normal checks: instead of you polling a URL, your cron job or worker pings the monitor on schedule. If the expected ping is late, you get alerted — catching silent job failures that have no endpoint to poll.
