is built on Prometheus AlertManager, which enables sophisticated routing, grouping, and notification management. You can configure the AlertManager to send notifications to targets via email (SMTP) or webhook endpoints.
It performs the following steps:
Alert generation. Prometheus evaluates alert rules against metrics and generates alerts.
Alert processing. AlertManager receives alerts from Prometheus.
Alert grouping. Similar alerts are grouped based on configurable labels.
Alert notification. Notifications are sent to configured targets (for example, SMTP and webhooks).
