Part V. Alerting

If you want to be woken up at 3 a.m. by your monitoring system,1 these are the chapters for you.

Building on the previous chapter, Chapter 18 covers alerting rules in Prometheus, which offer you the ability to alert on far more than simple thresholds.

Once you have alerts firing in Prometheus, the Alertmanager converts those into notifications while attempting to group and throttle notifications to increase the value of each notification, as explained in Chapter 19.
