About label matching for alert suppression

Grafana suppresses notifications only for alerts with labels that match all the "Matching Labels" specified in the silence.

  • The Label field is the name of the label to match. It must exactly match the label name.

  • The Operator field is the operator to match against the label value. The available operators are:

    • =: Select labels that are exactly equal to the provided string.
    • !=: Select labels that are not equal to the provided string.
    • =~: Select labels that regex-match the provided string.
    • !~: Select labels that do not regex-match the provided string.

  • The Value field matches against the corresponding value for the specified Label name. How it matches depends on the Operator value.
