Alert on what users experience (error rate, latency, availability, freshness) with thresholds tied to objectives, route by urgency, and turn every noisy alert into either a fix or a deletion.

Goal

Wake someone only when users are affected or soon will be, with enough context to act, and keep the alert set small enough that each one is taken seriously.

Prerequisites

Service level indicators measured at the edge, and an on-call arrangement with a documented escalation path.

Steps

Write alerts for symptoms — error ratio above target, latency percentiles above target, the site unreachable, data staleness — as the cited chapter advises; causes (CPU high, disk 80%) become tickets or dashboards, not pages.
Tie thresholds to objectives and burn rates: page when the error budget is being consumed fast enough to be exhausted within hours.
Attach a runbook link and the key dashboards to every alert; state what to check first.
Distinguish paging alerts from tickets; anything that can wait until working hours is a ticket.
Review alerts weekly: every alert that fired without action gets tuned or removed.

Expected result

Few pages, each actionable; incidents are noticed by monitoring before users report them; the on-call engineer trusts the pager.

Limits and test basis

Symptom alerts detect late for slow degradations; add a small number of leading indicators (queue depth, disk full forecast) with lower urgency. The principles follow the cited chapter.
