Prometheus AlertManager is the component that manages sending, inhibition and silencing of the alerts generated from Prometheus. The AlertManager can be configured to send alerts to variety of receivers. Refer [Prometheus AlertManager receivers](https://prometheus.io/docs/alerting/latest/configuration/#receiver) for more details.

Follow below steps to enable and use AlertManager.
