Description:

Starting RHOCP 4.19, Developer View is disabled by default. So, project admin (or developer)  can't view the metrics directly until developer view is enabled. In the documentation, the link [1] and [2], it is not mentioned to enable developer view as a prerequisite.

For developers to view metrics in OCP webconsole, it is mandatory to enable developer view (to be enabled by cluster-admin) to allow users to view application metrics in developer view.

Document[3] must be cross linked in [1] and  [2] , so that developers are that developer view needs to be enabled first.
