We are seeing inconsistency in view agents from Metric View. We do not see all the agent in Agent View that we see in Metric View.
That is a known limitation. We are not able (at this time) to filter metric view by universes, but we are able to filter agents view by universes, and we do it.
That is the reason why you are able to see all the agents in metric tree without having the admin privilege. But in agents view, there you can see only the agents, created under the universe you are permitted to read.
In other words you have to sign in as admin, if you want to see the universe called "ALL MY UNIVERSES" and the agent tile called "All agents".
