Alertmanager is the alert routing service in the logs stack. On Smithflix it receives alerts from Prometheus and delivers them to ntfy through the companion alertmanager-ntfy-bridge service.
This page documents the alertmanager service and its operational relationship with alertmanager-ntfy-bridge. It does not replace the ntfy page.
