Monitoring oracle_listener remotely

Hi,

As we can monitor oracle_database targets from remote agents, can we monitor oracle_listener target as well and how?

My env is two nodes AIX HACMP and have Agents on both nodes.

The listener runs on CNAME, so when listener runs on node A, CNAME points to node A, when HACMP moves to other node B, we point CNAME to node B and also start listener on node B. But I want to monitor both database and listener from node A only.  I have no issue in database monitoring. But listeners shows as down. Is it possible ?

Thanks,
