I tried doing auto-discovery of my ESXi host, and it showed up just fine. However, when I go to add it, the hostname doesn't work (says invalid hostname), so I add it by IP address, but that doesn't work either… it gives me an error saying it “failed to get configuration from agent”. Any ideas why it won't add, or anything I can try? There is no agent that I know of for ESXi, I was told it was agent-less. Is this a DNS or hostname issue? I'm using uptime 5.4 on a Windows Box.
