+Istiod is build with a flexible introspection framework, called ControlZ, which makes it easy to inspect and manipulate the internal state
+of an istiod instance. Istiod opens a port which can be used from a web browser to get an interactive view into its state,
+or via REST for access and control from external tools.
 
-Mixer, Pilot, and Galley all implement the ControlZ functionality. When these components start, a message is logged indicating the
-IP address and port to connect to in order to interact with ControlZ.

-To access the ControlZ page of deployed components (i.e. Mixer, Galley, Pilot), you can port-forward their ControlZ endpoints
+To access the ControlZ page of istiod, you can port-forward its ControlZ endpoint
 locally and connect through your local browser:
 
 {{< text bash >}}
-$ istioctl dashboard controlz <podname>
+$ istioctl dashboard controlz <istiod pod name> -n istio-system
 {{< /text >}}
 
 This will redirect the component's ControlZ page to `http://localhost:9876` for remote access.
