How to group noisy alerts into one incident
Group noisy alerts into one incident: pick grouping labels, set group_by and timers, inhibit downstream symptoms and key incidents on the group key.
Alert triage is the work between an alert firing and a person deciding what to do about it. Most teams do too much of it by hand: one database blip pages three people, a deploy sets off twenty alerts that share a single cause, and the real problem sits in the middle of the noise.
These guides are for the engineers who hold the pager on a small team without a dedicated operations group. They cover grouping related alerts into one incident, routing each alert to the person who owns the service, setting thresholds that match real traffic and cutting the pages that wake people up for nothing. Each guide shows the configuration to copy, from Alertmanager routes to incident keys, and how to check it works before your next night on call.
