University of Toronto ☛ The effects of silences (et al) in Prometheus Alertmanager
Prometheus Alertmanager has various features that make it 'silence' alerts. Alerts can be inhibited by other alerts, they can be explicitly silenced, and a route can be muted at certain times or only active at certain times. The Alertmanager documentation generally describes all of these as "suppressing notifications" or causing a route to "not send any notifications".
