I am on 11.1.0 OEM grid control. One of the cluster host's agent is down. But the same is not reported on the Pie chart of OEM home page.
When i click on the Host performance tab, it reports the below error.
An error has occurred!
Unable to obtain data for target hostA. The target may be down. Switching to the last 24 hrs view.
But for the RAC instance running on this node, OEM does not report any error. It gives all details as if the agent is up. (even after waiting for 10 min)
In the same OEM when the agent on any other target is down, it is reported in the pie chart within 5 min.
I am not clear what is wrong with this and how to fix it.
