We upgraded our vCenter servers to 5.1 and since then the usage meter (v3.0.2) has been unable to login.
Message is: "A collection from x.x.x.x, begun at 2013-05-06 12:05:01, failed at 2013-05-06 12:05:09. com.vmware.vim25.InvalidLoginFaultMsg: Cannot complete login due to an incorrect user name or password"
I can login with same credentials to each vCenter servers with the VMware client.
The 3 monitored hosts still show as v 5.0.0 under the Manage/Products TAB. I have tried deleteing all 3 servers and re-adding, but all I get is a message that says do I wan't to reactivate, and the servers come back in the old state.
Anyway I can get the collections working again?
