Dropping Specific Alerts¶

This guide defines a sink that receives all notifications except for a specific alert.

To drop a specific notification globally from all sinks, see Silencing Alerts.

Exclude Alerts by Alert Name¶

Using sink scopes, you can drop all alerts with a specific name:

sinksConfig:
- slack_sink:
    name: main_sink
    slack_channel: main-notifications
    api_key: secret-key
    - scope:
        exclude:
        # don't send notifications where the alert name is ANY of the following
        - identifier: [ImagePullBackoff, CrashLoopBackoff, CPUThrottlingHigh]

Exclude Alert by Namespace¶

Using sink scopes, you can drop all alerts from a specific namespace:

sinksConfig:
- slack_sink:
    name: other_slack_sink
    slack_channel: no-pods-or-deployments
    api_key: secret-key
    scope:
      exclude:
        - namespace: ["kube-system"]
