Description

Problem Statement

Prometheus supplies an ALERTS metric tracking the firing alerts. Alertmanager has the ability to silence metrics. But there is no metrics exposed by Alertmanager to track the alerts that are silenced.

Proposed Solution

Introduce an alertmanager metric for alerts that are being silenced. This can further be extended to other types of suppressions (inhibition rules)

Benefits

  • Improved tracking of silence
  • Better Auditing

Research direction

The issue names no files, tests, or entry points. Start by locating Alertmanager's existing metrics and silence handling, then determine the metric's behavior for silenced alerts and how it could extend to inhibition rules. Done means silenced alerts are exposed for tracking and auditing, with coverage for the resulting behavior.
