The logs is misleading. Ping really means request... if you do the same for an HTTP monitor it doesn't state "Request Sent" is states (_do_ping) etc.

 

Can you do a "tmsh list ltm monitor (monitor name)" for output for the monitor that is failing?

 

Also try using either telnet or socat to connect to the IP:PORT combination instead of using ICMP, which goes as far as layer 3, while your monitor should test all the way to layer 7.

And also the telnet to the pool member is successful.
