7 (Optional) Enter the persistence expiration time for the cookie in seconds.
As an example, for L7 load balancing with a TCP source IP, the persistence entry times out if no new
TCP connections are made for the specified expiration time, even if the existing connections are still
live.
8 (Optional) Click the Health Check tab and proceed to the Define Virtual Server Health Check
Settings topic to continue defining the virtual server in the NSX load balancer component.
Define Virtual Server Health Check Settings
By selecting the Customize option on the General tab, you can specify how, or if, the NSX load balancer
performs health checks on pool members within the virtual server.
The default health check protocol and health check port settings match the protocol and port settings on
the General tab.
For related information see Create a Service Monitor in NSX Product Documentation at
https://www.vmware.com/support/pubs/nsx_pubs.html. Note that the NSX documentation refers to the
virtual server member as a pool member.
Prerequisites
Define Virtual Server General Settings.
Procedure
1 (Optional) Select a heath check protocol in the Health check protocol drop-down menu to specify
how the pool member is accessed when the load balancer listens to determine the health of the pool
member.
The protocol options are HTTP, HTTPS, TCP, ICMP, UDP, and None.
You can also accept the default protocol as specified on the General tab.
2 (Optional) Enter a value in the Health check port box to specify on which port the load balancer
listens to monitor the health of the virtual server member or pool member.
Note that the NSX documentation refers to a virtual server member as a pool member.
The HTTP, HTTPS, and TCP protocols can share a port with UDP. For example, if service 1 uses
TCP, HTTP, or HTTPS on port 80, service 2 can use UDP on port 80. If service 1 uses UDP on port
80 though, service 2 cannot use UDP on port 80.
3 Enter the Interval value in seconds at which a server is to be pinged.
4 Enter the maximum Timeout value in seconds within which a response from the server must be
received.
5 Enter a Max. retries value as the number of times the server must be pinged before it is declared
down.
