What’s new in Grafana v8.0

Grafana includes built-in support for Prometheus Alertmanager. Once you add it as a data source, you can use the Grafana alerting UI to manage silences, contact points as well as notification policies. A drop down option in these pages allows you to switch between Grafana and any configured Alertmanager data sources. https://grafana.com/docs/grafana/latest/datasources/alertmanager/
