The visualization tool is no longer available. Left the visualizations since they are still helpful in explaining the concepts.

 As you can see, the new **Filter** definition will be a mandatory step to pass before the control goes to the **Match** section. The **Filter** basically will accept or reject the **Event** based on its `type` and rule. For our example we want to discard any user **logout** action. We only care about the **logins**. The way to accomplish this, is doing a `grep` inside the **Filter** to exclude any message on which `action` key have the **logout** string.

 The new configuration contains a `@label` parameter under `source` indicating that the further steps will take place on the `@STAGING` label section. The expectation is that every event reported on the **Source**, the **Routing Engine** will continue processing on `@STAGING`. Hence, it will skip the old filter definition.
