We were facing lot of performance issue in our cluster (elastic version 7.1, 3 md and 2d on linux boxes). Then we created two separate ingest node but still performance issue was there.
Our nodes were going own randomly. then we disable the ESMS capability and after than cluster is pretty stable but again our ingest node went down last week.
We want to enable ESMS but afraid it can hurt cluster.
Is there any known issue with ESMS ? And how can we decide the correct structure of cluster? I mean how many master ,data,ingest and coordinate?
