We have two Windows 2012 Web\security server sitting behind the NSX firewall. Last month one quit responding to users when a windows update was installed. Yet the LB never saw the issue on the server that the ports were not responding. We have the monitoring of TCP on to the server pool with the server showing port 8443.
What other ports need to be monitored to show the server is down and to stop allowing users to access if an issue arises?
Can services be monitored by the LB?
What else needs to be monitored by NSX LB for isolating the server when an issue arises?
