Show HN: Simple Cron Monitoring Tool

So, do you ever experience cases where cron jobs don’t run?

In the 30+ years I have been doing Unix and Unix-like OSes, I have never once had a case where a cron job failed to fire. Sure, they haven’t always worked as desired, but that’s been more due to running out of disk space or some other required resource. Cron did it’s job just fine, it was the script that crapped out.

So, is there really a pressing need for this kind of solution?
