     It's important to note that the `drain-data` parameter has precedence over `drain-type`parameter. If the `include-metrics-deprecated` parameter is present in the Syslog URL, the drain forwards logs, application container metrics, and traces.
 
+    You can filter which log sources are forwarded to your syslog drain using the `include-source-types` or `exclude-source-types` URL query parameters. The `include-source-types` parameter forwards only logs from the specified source types, while `exclude-source-types` forwards all logs except those from the specified source types. Both parameters accept a comma-separated list of source types, and you can only use one parameter at a time. For a list of valid source types, see [App logging in Cloud Foundry](../deploy-apps/streaming-logs.html).
+
+    Example: Forward only application and router logs:
+    <pre class="terminal">
+    $ cf create-user-provided-service my_app_drain -l syslog://logs.example.com:1234?include-source-types=app,rtr
+    </pre>
+
+    Example: Forward all logs except staging logs:
+    <pre class="terminal">
+    $ cf create-user-provided-service my_app_drain -l syslog://logs.example.com:1234?exclude-source-types=stg
+    </pre>
