6 years ago Topology discovered fine by 2.1.15 :
Binlog servers are- 10.41.191.61 10.41.191.62
In 3.1.12 , Orch displays a disjointed set. Seems its unable to discover the linkage between Binlog-server and Master:
Orch didnt discover the other remaining (10.41.191.62) binlog server at all. When trying to discover it through CLI, we get following debug messages:

Cluster topology : 1 Master having a number of direct slaves , including 2 binlog servers.
Binlog servers are not being discovered by orchestrator. Hence, cluster becomes disjointed when these binlog servers are made to be intermediate masters for slaves.
This is being observed in the branch: tree/fix-analysis-query (#632 ). Although seems working fine on version 2.1.5.
On orch version 2.1.5: Maxscale binlog-sever- 10.41.191.61
tree/fix-analysis-query (#632 ) :
