Keep Only Matching Events

Use Case​

Use a keep-list pattern when a feed contains many events but you only want to publish events that match specific rules.

Config​

config.yaml excerpt
filters:
  - description: "Keep engineering on-call events"
    match:
      summary:
        contains: "Roster"
        contains_any:
          - "Primary On Call"
          - "Secondary On Call"
    stop: true

  - description: "Remove everything else"
    remove: true

How It Works​

String match conditions are combined with AND logic. In this example, the event summary must contain Roster and must also contain either Primary On Call or Secondary On Call.

The first filter uses stop: true so matching events are kept and later filters do not run for them. The final filter has no match rules, so it matches any event that reaches it and removes it.
