We have certain cron jobs that if they failed we could be losing thousands of dollars an hour.
Of course they're tested, and you're right they've worked fine for a looooong time.
But I don't care if they "normally work fine", I need to know immediately if it didn't run for any reason. We self hosted a cron monitor, it was free and only took less then a day to add and have fully integrated, including text message and MS teams notifications.
