now it seems a lot better
You seem to have a bigger problem - the fact that all other objects are "grey" most likely means that vcops has stopped collecting data for this environment.
Judging by the Anomalies badge, something happens ~3 hours before you did that snapshot.
Please look at
1) Faults badge for any problems indication
2) Alerts page for the World or vCenter objects. You will most likely have some administrative (or fault) alert there. Admin* alerts have the blue icon
