Which version of Grafana has the silences feature? I downloaded grafana-8.1.1.windows-amd64 but i dont find the option in Alerting section? Do we need to enable anything explicitly?
Are you speaking about the new Unified Alerting in version 8? If so, then yes, you must still enable the feature toggle for ngalert in your grafana configuration. As in GF_FEATURE_TOGGLES_ENABLE=ngalert
