NimbostratusHelp http health monitor
I need help setting up http application monitoring on bigip.
I did the setup this way, and it worked.
Send string
GET / HTTP / 1.1 \ r \ nHost: test.example.com \ r \ nConnection: Close \ r \ n \ r \ n
Recived string
HTTP / 1.1 302 Found
I need to monitor all applications that are on my servers poll but it doesn't work, when I insert more than one application in send string, my node in the pool goes offline I believe that some parameter must be wrong.
I did it this way and it doesn't work.
Send string
GET / HTTP / 1.1 \ r \ nHost: test1.example.com; test2@example.com; test3@example.com \ r \ nConnection: Close \ r \ n \ r \ n

Your send string, "GET / HTTP / 1.1 \ r \ nHost: test1.example.com; test2@example.com; test3@example.com \ r \ nConnection: Close \ r \ n \ r \ n" violates RFC, you can have only one host in a host header. In this situation I can only assume your server interprets the value of the host header as one long string "test1.example.com; test2@example.com; test3@example.com" instead of your intention of 3 unique values.
Do your servers strictly require a value for the Host header? RFC states that it can be a null (empty) value so if all your servers do not strictly require a value then just leave it empty. If they do require a strict value then you will need to create multiple monitors and apply them to each pool member individually as required.
"GET / HTTP / 1.1 \ r \ nHost:\ r \ nConnection: Close \ r \ n \ r \ n"
TTI_do_BrasilI understand Andrew, I will have to apply to create several monitoring and apply individually to the members of the pool, I did the test here and it worked.
Thank you very much Andrew for your support.
