In our lab we have a stand alone VM ESX 5.1 environment. I went to look at some historical Performance Data I saw blank spaces in the graphs.
I would like to know where vSphere is pulling this data from, if it stores it somewhere, if it can be re-imported, and how to figure out how this happened in the first place.
The only thing that is noteworthy is that we have sent logfiles up to vmware 2 x last week. Could this data have been removed from that? I can't see how, but its the only abnormal event I am aware of.
Any advise on where to go with this is appreciated.
Thanks
