Use case
A nightly pipeline, a backup, a CI job. It works, so nobody watches it, and the only signal it ever produces is the one it fails to send.
A scheduler is disabled during a deploy, or a machine reboots and the timer does not come back. There is no error, because nothing ran to produce one.
Discovered by whoever needs the output, which is the worst possible reader of that news.
One line in the job. No credential of yours reaches us, because there is nothing for us to log in to. The full posture.
Nightly pipeline check-in
If the key expires, that’s Check broken, never Missed - broken access is its own alert, and it says whose job it is to fix.
Set it up in a sentence:
“Our nightly job should ping when it finishes, every day by 2am UTC, 30 minute grace.”
