Hello,
a standard monitor always will monitor the port configured in the node config from the pool. To monitor other ports, you need a scripted health monitor.
Here's an example HTTP/S monitor I wrote in Python, although not performance optimized, as it runs an additional subprocess. It reads additional parameters through the health monitor to specify, what port you want to monitor and what path.
Upload the script to Extra Files/Monitors, then create a new program based monitor and add the parameters below...
#!/usr/bin/env python
# HTTPS health monitor for different port than node port

add 3 arguments to the monitor to specify, path, port and timeout:
