Hi @VitorBarroso, you can follow the steps in our [documentation](https://www.elastic.co/guide/en/security/current/rules-ui-create.html#rules-ui-create) to create detection rules configured to look for external event data. For example, you could create a "Custom Query" rule that searches for source data matching `event.kind: "alert"`. Typically, events that appear in the External alert trend graph have an "event.kind" value of "alert".
