Guest Introspection(GI) NSX Appliance gets Deleted Automatically after vCenter Disconnect

We had 2 vCenters setup in that way and one of the vCenter is showing some odd symptoms. We are seeing some weird actions with NSX manager in one vCenter. So, I lose the connection to the vCenter from fat client, web client is still fine and doesn’t kick me off. In the process, the Guest Introspection appliance or GI VMs (appliance managed by NSX) from some random hosts were getting deleted automatically - from the cluster that was protected with NSX.

So, rather than rebooting server fr...

VMWare ESXi Host showing Up Time as 0 second

I have seen this more on 5.5 ESXi hosts but the host shows the up time as 0 seconds and CPU and Memory percentage as 0% Easiest way to resolve this is to put the host in maintenance mode and then restart the management agents on the ESXi hosts. #esxcli services.sh restart But to be more cleaner I prefer to put host in maintenance mode and reboot the host to get the clean state.
