how GTM monitor work , what is the process of a GTM https montor

create monitor https m-test-host.c-name.test.doamin.com-HTTPS-8090 interval 15 timeout 60 send "HEAD /test.html HTTP/1.1\r\nHost: test-host.test.doamin.com:8090\r\n\r\n" recv "HTTP/1.[01] [23][0-9][0-9]"

exit
modify server server2
virtual-servers add { vs-dc2_test-host-8090 { destination 172.16.5.12:8090 } }

create wideip a test-host.c-name.test.doamin.com { pools add { p-test-host.c-name.test.doamin.com }  }

environment setting: a cname has been add:

• test.host.test.domain.com test.host.c-name.test.domain.com
• domain test.domain.com is configured to be resolved by the above GTM
• GTM listen to the DNS resolve request for test.domain.com

I have a GTM configuration above , I am wondering how GTM https monitor works, here is my understandings, is that correct ?

1. GTM detect the aliveness with test command: curl --insecure -v https://test-host.test.doamin.com:8090/test.html
2. GTM send the DNS resolve request for test-host.test.doamin.com , since there is Cname , GTM will request DNS resolve for

test.host.c-name.test.domain.com

3. since the c-name.test.domain.com will be resolve by itself , GTM check the configuration , found that a pool is configured for

test-host.test.doamin.com

4, GTM check the pool member aliveness with command ,

curl --insecure -v https://192.168.11.21:8090/test.html

curl --insecure -v https://172.16.5.12:8090/test.html

if any of the pool member is up , the pool will be up , the wideip will be up.
