NimbostratusHealth monitor to pool members
Hello, I have 2 node members belong to pool that has been monitored with x port which is also service port. both 2 node's y port was opened and i want to have health monitor different then service port .
GET /ping/index HTTP/1.1\r\nHost: a.b.c.d:x\r\nConnection: close\r\n that monitor working properly. GET /ping/index HTTP/1.1\r\nHost: a.b.c.d:y \r\nConnection: close\r\n is not working properly.
when i add health monitor which is "GET /ping/index HTTP/1.1\r\nHost: a.b.c.d:y \r\nConnection: close\r\n " to pool members is not working. do u have any idea why its not working or how could i make it work ?

What’s the response on port y and what’s your receive string? Sounds like it’s not using the same setup and responding differently. Run it with curl or netcat on the command line and see if both ports respond the same way.

You can also try enabling health monitor logging on the pool temporarily to see what response the F5 is receiving back from the pool members (the F5 will create a log file in the /var/log/monitors/ directory)
1) Enable logging on the pool
tmsh modify ltm pool members modify { all { logging enabled } }2) Check the logs from bash
cat /var/log/monitors/3) Disable logging on the pool
tmsh modify ltm pool members modify { all { logging disabled } }

Configure the Alias port in health monitor as port Y.

Hi Mate,
It is because the health monitor is configured for port X and you might missed configuring port Y as alias so BIG IP will ignore it.
Configure port Y as alias in the health monitor and verify the status.
