On Health Monitor
Hello, trying to understand how this health monitor I created behaves.
I created a http virtual server on port 8082 and a pool with just one server member.
The pool has a health monitor of http type with the send string GET /service_status.html\r\n\r\n
a receive string .GOOD and receive disable string of .MAINTENANCE
Right now the html page is showing Service Status is MAINTENANCE
The pool is still showing to be UP. What does really happened to the server? Is it supposed to be disabled? Thanks.

If "receive disable string" is MAINTENANCE and if the /service_status.html page is serving MAINTENANCE, then the pool member should not be UP.
See this SOL13397 for the right formatting.
An example:
GET /index.html HTTP/1.1\r\nHost: host.domain.com\r\nConnection: CloseIf you are still running into issues after fixing any formatting issues, I would recommend running curl from the F5's bash shell. Example:
curl -H "Host: domain.com" http://10.10.10.10/service_status.htmlI am assuming that the IP of the pool member is 10.10.10.10 and that it is listening on port 80. This will help you to identify the response that the F5 is seeing.
If the pool member is listening on a different port, you would have to configure the HTTP monitor to check the pool member on the right port.

Thanks Odaah,
This is what I get at the moment without changing the monitor set up: [rfenol@slpma1nagioswan ~]$ curl -H "Host: esignal.com" http://172.24.128.60:8082/service_status.html Service Status is MAINTENANCE
Looking at the pool is still showing green circle and the memebr availability is showing Availability: Available (Disabled) - Pool member is avaiable, monitor disable
So what does Available (Disabled) means?

Hi Odaah,
next to the pool member I see a black circle.

Black Circle - A user has actively disabled an available object.
I think the circle is there because the server is responding to the monitor request and the black color is for disabled status because the response matches the configured disable string.
