Strange data in Fusion Middleware Console regarding OHS

I have an OHS cluster in my environment. Due to a change I needed to bounce the servers one by one.


As this is a production environment I wanted to make sure that everything is working - so I decided to restart them one after another.


I was then looking at the performance page of the OHS and saw the following:

Obviously everything was running o the first host. The access_log showed the typical requests.

So I decided to restart the second server as well (proceed - fingers crossed).

When I evr find out what caused this I will update this posting.
