does the keepalive port need to be the same as the service port for this example of 1 IP and multiple instances with different port numbers. the keepalive type is http.

thanks

the keepalive port will be the same as the port configured for the service/rserver unless specifically configured to something else.

You could reuse the same port for the keepalive but different port for the application.

But normally you would want to poll the ports that you are using.
