Currently, when you display the topology from the command line, it only displays the Hostname and Port, however, it could be helpful (it is for us that we manage everything with IP's) to display as well the InstanceAlias if is set.
So instead of this:
10.0.0.2 [0s,ok,5.7.30-33-log,rw,MIXED,>>,P-GTID]
+ 10.0.0.3 [0s,ok,5.7.30-33-log,ro,MIXED,>>,P-GTID]
+ 10.0.0.4 [0s,ok,5.7.30-33-log,ro,MIXED,>>,P-GTID]
Display this:
10.0.0.8 (mysql1) [0s,ok,5.7.30-33-log,rw,MIXED,>>,P-GTID]
+ 10.0.0.3 (mysql2) [0s,ok,5.7.30-33-log,ro,MIXED,>>,P-GTID]
+ 10.0.0.4 (mysql3) [0s,ok,5.7.30-33-log,ro,MIXED,>>,P-GTID]
