VMware NSX Manager Not Showing up in vCenter inventory

The NSX manager was deployed and configured correctly. It was showing up in vCenter, when I configured it. After few days when I checked suddenly NSX disappeared from the vCenter inventory. I logged in to NSX manager and it was all fine. It was showing as connected with its respective vCenter but wasn't showing up in the vCenter. I tried to restart the vCenter services and vCenter server that did not resolve the issue.

Easiest fix that worked with me for this issue is to restart the NSX manager and then it shows up back in vCenter.

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.

It doesn't recognizes those GI VMs and starts de...

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.

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.
