We audit our code regularly, why don't we audit our monitoring?

I've been thinking about this for a while. We have automated checks for code quality, security, and test coverage but for monitoring we just hope it's fine. Last year I was on call when a critical service went down. Took us a while to even get paged because the alert that was supposed to catch it had been disabled three months earlier during a maintenance window. Nobody reenabled in and no one noticed.
