How to configure the Splunk Deployment Monitor app on a multisite cluster in order to see all Indexers in the UI?

[aof]

I have one cluster in two geographic sites.
Server1 (SearchHead), server3(Indexer), server5(Indexer) on site1 AND Server2(SearchHead), server4(Indexer), server6(Indexer) on site 2

Cluster Master replication configuration :
[clustering]
access_logging_for_heartbeats = 1
available_sites = site1,site2
max_peer_build_load = 5
mode = master
multisite = true
pass4SymmKey = xxxxxxxxxxxxxxxxx
replication_factor = 2
site_replication_factor = origin:1,site1:1,site2:1,total:2
site_search_factor = origin:1,site1:1,site2:1,total:2

The Search Heads send their logs to all four indexers in LB mode.

The Deployment Monitor app is installed on server 1. On the DM interface I can see only the servers 1, 2 and 3.
If I change #site=site1 by #site=site2 (server.conf  stanza [general]), on the DM interface I can see now only the servers 2, 4 and 6.
Are there some settings to configure in order to see all the servers on the DM interface?

However with the SoS app on the SearchHead (Server1), all components of my architecture are visible.

You need to join the SH with the Deployment Monitor Console to the remote cluster, as a search peer.

I believe this is a search affinity issue. Try ensuring the deployment monitor instance is configured to use all indexers as distributed search peers.

Hi,
How do you configure the Deploymment Monitor to use all indexers as distributed search peers ?
