About Prometheus Alertmanager

Alertmanager receives alerts sent by client applications such as the Prometheus server and decides who hears about them. It removes duplicates, groups similar alerts into a single notification, and routes them to receivers such as email, PagerDuty, OpsGenie or a webhook.

It also handles silencing, so known issues stay quiet during maintenance, and inhibition, which suppresses alerts that are only symptoms of a larger failure. Rules are defined in a configuration file. It suits anyone running Prometheus who needs alerts delivered without floods of pages.

Strengths

  • Groups hundreds of related alerts into one notification
  • Silencing and inhibition to cut alert noise
  • Routes to email, PagerDuty, OpsGenie and webhooks

Limitations

  • Configured through files rather than a full graphical interface
  • Designed around Prometheus and its alerting rules
