What is it?
Alertmanager is the service (and software) in charge of collecting, de-duplicating and sending notifications for alerts across WMF infrastructure. It is part of the Prometheus ecosystem and therefore Prometheus itself has native support to act as Alertmanager client. The alerts dashboard, implemented by Karma, can be reached at https://alerts.wikimedia.org/. As of Jan 2021 the dashboard is available for SSO users only, however a read-only version is possible as well.

Software stack
When talking about the Alertmanager stack as a whole it is useful to list its components as deployed at Wikimedia Foundation, namely the following software is:
- Alertmanager the daemon actually in charge of handling alerts and sending out notifications
- Karma the dashboard/UI for Alertmanager alerts, it powers https://alerts.wikimedia.org
- kthxbye implements the "acknowledgement" functionality for alerts
- alertmanager-irc-relay forwards alerts to IRC channels
- prometheus-icinga-exporter compatibility shim to forward active Icinga alerts to Alertmanager, also provides Prometheus-style metrics for Icinga
