How do you handle cron jobs that silently stop working? (lemmy.world)

Had a backup script running via cron for months. Worked fine until it didn't — turns out the disk filled up three weeks ago and the job started failing silently. Nobody noticed until we actually needed a restore.

The obvious answer is "check your logs" but let's be honest, nobody's reading cron logs daily for 15 different scheduled tasks across 4 servers.

What's your setup for making sure crons are actually completing? Do you just grep logs periodically, or do you have something more structured? Curious how others handle this without turning it into a whole project.

If it were critical I would set up an "email me on script run failure" wrap around the individual cron jobs. Simple exit code check, potentially with console output as email body is simple and useful.
