Last night we received a notification from vCenter saying that it couldn't connect to the agent on one of our hosts, and that the "Host and Power status" was in error and the server was disconnected.
There were no issues with any guests running on the host, so we left it for the morning.
But when checking the task & event and alert logs, we find nothing. The host logs also show no issues at that time.
No reference to anything having gone wrong, nothing to tie that notification back to.
Even if the issue was temporary and fixed itself, should't there be something in the log indicating that some type of trouble occurred?
Also, if it in fact automatically recovered, why didn't vCenter send its usual "Oh hai, everythings fine nao" notification when the system recovered?
