The Alias Address and port is used for transparent monitors - where LTM checks an external address through a device such as a proxy or gateway. If you have applied the monitor to the pool then LTM will send that monitor to the ip address and port for that pool member. If you apply the monitor to the node then it will send the monitor only to that node.

 

You should apply the icmp monitor at the node level as the default node monitor and assign the DNS monitor at the pool level.
