Alerting Overview

Alerting with Prometheus is separated into two parts. Alerting rules in Prometheus servers send alerts to an Alertmanager. The Alertmanager then manages those alerts, including silencing, inhibition, aggregation and sending out notifications via methods such as email, PagerDuty and HipChat.

The main steps to setting up alerting and notifications are:

  • Setup and configure the Alertmanager
  • Configure Prometheus to talk to the Alertmanager with the -alertmanager.url flag
  • Create alerting rules in Prometheus
