Alerting & On-Call with Prometheus Alertmanager

SLO-based alerts routed to the right person, each with a runbook

2-3 weeks build

Overview

The part of monitoring that wakes someone up, and only when it should. Alert rules are written against an SLO, with multi-window burn-rate alerts that page for fast burns and open a ticket for slow ones. Alertmanager groups, deduplicates and routes by severity and team, silences cover planned work, and a small on-call rota decides who is paged. Every alert links to a runbook. Runs locally in Docker.

What makes it stand up

  • 01SLO defined first, then alerts derived from its error budget
  • 02Multi-window burn-rate alerts that separate pages from tickets
  • 03Routing tree by team and severity with grouping and inhibition
  • 04Silences for maintenance windows, created and expired from a script
  • 05On-call rota service and a runbook linked from every alert

Module breakdown

  1. 01

    SLOs

    Availability and latency objectives with recording rules.

  2. 02

    Alert rules

    Burn-rate and symptom-based rules unit-tested with promtool.

  3. 03

    Routing

    Alertmanager receivers, grouping, inhibition and repeat intervals.

  4. 04

    On-call

    Rota service that resolves who is on call and notifies them.

  5. 05

    Runbooks

    One page per alert: meaning, checks and first actions.

After this, you will be able to

  • Explain error budgets and why burn rate beats a static threshold
  • Defend which alerts page a human and which only open a ticket
  • Demo an injected outage paging the on-call person with a runbook
