What is AlertManager?
Prometheus component that handles alert routing, grouping, and notification delivery.
AlertManager is a component of the Prometheus ecosystem that receives alerts from Prometheus and handles deduplication, grouping, silencing, and routing them to the correct receiver (Slack, PagerDuty, email, etc.). It uses a routing tree to match alert labels and send notifications. Alert grouping reduces notification noise by batching related alerts. Silences let you mute alerts during planned maintenance windows.
