When you have small environment max 50 (or something like that) UF/HF on your DS, you could use DS as a MC node. If you have lot of nodes then you need a separate DS and also I propose to use separate SH and IDX cluster with at least 2-3 peers and manager. Then you probably need a separate MC, don't put it into SH or individual search peer! In those cases you should add SH/IDX node as a search peer (in DS) in distributed search GUI to it to able to query anything from SH/IDX logs. Also you should send your DS's logs to that node (as a best practices). Then you should configure correct roles for all those servers DS -> DS + MC (maybe SH+KVstore also) SH/IDX -> SH, IDX, KVstore add LM role to node which you are using as LM. Basically that could be you DS/MC or SH/IDX After that you can enable FWD monitoring on MC's Setting. Now you should see those on correct groups/roles on MC.
