How to Check Up Time of ESXi Host or Virtual Machine from vCenter Server

To check up time of ESXi host from vCenter server -

Logon to vCenter Server -

If using C# (fat) client - click on cluster - on right side pane click on Hosts - select the up time option by right clicking on the header. The column will be added at the end. You can drag and drop column to place it in your view.

If using HTML client - click on cluster - on right side pane click on Hosts - select the up time attribute from show/hide column by clicking on the header

If using web (Flash) client - click on cluster - on right side pane click on related objects - hosts - right click on the header to show/hide column - click on up time attribute

Similarly, you can check the up time for a virtual machine by clicking on the virtual machine tab instead of host tab, but only caveat is vCenter gives you up time of a virtual machine according to reboots performed from the vCenter. So, rather than rebooting server from vCenter inventory, if server is rebooted at OS level itself -the up time may not be accurate in VMware vCenter inventory.

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

I was working in an environment where NSX was configured with Trend micro deep security in VDI environment to protect VDI desktops.

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. When I checked the windows logs (as vCenter was on windows server) this is what I saw - I opened a case with VMware support - They reviewed the NSX logs and came to conclusion that this is not the NSX issue but it's vCenter that is deleting those VMs. vCenter gets disconnected for few seconds, then connects back. It doesn't recognizes those GI VMs and starts de...

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.
