Show Notes

Don’t forget to check out the book itself! The Art of Monitoring.

Back in the day, James also wrote a book called Pro Nagios 2.0.

Three stages of monitoring maturity: - Manual, user-initiated, or no monitoring (aka Bridget’s example of “we know things are broken because the customer calls us to complain”) - Reactive - Proactive

“You will eventually get to CPU, memory, and disk, but a lot later after you start with the things you should really care about” - James

“Too much monitoring is binary - this thing either works or it doesn’t” - James
