Why architecture matters here

Alerting fails on noise. Architecture matters because rules + SLO + routing + review compose.

The architecture: every piece explained

The top strip is the pipeline. Signal source. Alert rules. Alertmanager. Routing.

The middle row is humans. Oncall schedule. Escalation policy. Burn rate alerts. Silence + inhibit.

The lower rows are ops. Runbook link. Metrics on alerts. Ops — alert reviews + tuning.

Alerting pipeline: rules → routing → oncall.

End-to-end flow

End-to-end: metric spikes. Rule matches. Alertmanager groups + routes to team. Primary oncall paged. Escalates to secondary if unacked. Burn-rate rule ensures SLO-aware alerts. Silences suppress during deploys.
