If you add monitoring tables to your high availability configuration, you must add either of the following to the interfaces entry for both servers before you can monitor the performance of the secondary and the primary companions:
loopback master tcp ether localhost port_number query tcp ether localhost port_number
Or,
loopback master tcp ether servername port_number query tcp ether servername port_number
where port_number is any open port on the primary companion.
