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.
6 Specify additional health check settings based on your selected Health check protocol.
a Enter the Method to be used for detecting server status. The options are GET, OPTIONS, and
POST.
b Enter the URL to be used in the request for detecting server status. This is the URL that is used
for by GET and POST ("/" by default) method options.
c In the Send text box, enter the string to be sent to the server after a connection is established.
In the Send text box, enter the string to be sent to the server after a connection is established.
d In the Receive text box, enter the string expected to receive from the server.
Only when the received string matches this definition is the server is considered as up.
The string can be a header or in the body of the response.
7 Click the Advanced tab and proceed to the Define Virtual Server Advanced Settings topic to continue
defining the virtual server in the NSX load balancer component.
To specify logging options, see Define Load Balancer Logging Options.
Define Virtual Server Advanced Settings
By selecting the Customize option on the General tab, you can customize the NSX load balancer
component to specify settings such as the number of concurrent connections that a single pool member
can recognize and the maximum number of concurrent connections that the virtual server can process.
