alertmanager notify specific slack groups based on severity

I want to set up Prometheus' Alertmanager so that when I get an alert, I check its severity. If it is "warning", I want to send the alert to the "warning" Slack channel. If it is "critical", send it to the "critical" Slack channel. How do I specify this in the alertmanager.yml?

Solution

  • You can do so by configuring matchers in route:

    route:
  receiver: 'slack-notifications-criticals'
  routes:
  - matchers:
      - severity = "warning"
    receiver: 'slack-notifications-warnings'
  - matchers:
      - severity = "critical"
    receiver: 'slack-notifications-criticals'

    And configuring recievers slack-notifications-warnings and slack-notifications-criticals with corresponding slack channels.

    Example of full configuration with different recipients depending on severity can be found here.
