Ask HN: How do you currently monitor cron jobs?

Sometimes a cron job fails and you won't even notice for weeks or months that it is failing unless you manually check things (e.g, check data on the db, check the logs, run the cron job manually and check if it will finish running successfully, etc...).

I'm curious on how do you currently monitor cron jobs?

Like how do you know immediately that your cron jobs are failing (e.g, it fails to run or it fails to finish running successfully because of an unexpected error)?

Currently, we are using CronMonit ( https://cronmonit.app/ ) which is a simple tool that we built that notifies us via email when our cron jobs fail. I'm curious what tool are you using or if you even use a cron monitoring tool at all?
