Hello! I have the next equipment: virtual machine 1: 12 CPU E5-2698 v4 @ 2.20GHz with 16Gb memory This server contains: logstash with -Xms256m -Xmx1g elastic (node.master: true node.data: false node.ingest: true) with -Xms4g -Xmx4g kibana hardware machine 1: 24 CPU X5660 @ 2.80GHz with 96Gb memory and 18Tb filesystem This server contains: elastic (node.master: false node.data: true node.ingest: true) with -Xms30g -Xmx30g hardware machine 2: 16 CPU E5620 @ 2.40GHz with 96Gb memory and 18Tb filesystem This server contains: elastic (node.master: false node.data: true node.ingest: true) with -Xms30g -Xmx30g Elastic, logstash and kibana version 6.1.2 with x-pack (basic license) My index rate 2000-3000 events per second with burst up to 15000-25000 events per second. When I have burst , My master elastic is down with error "out of memory". Than I added new elastic node: virtual machine 2 : 4 CPU E5-2698 v4 @ 2.20GHz with 8Gb memory This server contains: elastic (node.master: false node.data: false node.ingest: true) with -Xms6g -Xmx6g and change elastic on virtual machine 1 to elastic (node.master: true node.data: false node.ingest: true) with -Xms2g -Xmx2g Is it right? Who can give recommendations on how to use my servers more profitably? ---

You ideally want to have 3 master-eligible nodes in a cluster, so the cluster can continue operating even if 1 master nodes drops. I would therefore recommend the following: - Make both data nodes master eligible and set `minimum_master_nodes` to `2`. - Make the smaller node a dedicated master node by setting `node.ingest` to `false`. - Send all traffic directly to the two nodes holding data. Avoid sending any requests through the small dedicated master node. - Keep the dedicated ingest node you just added if you feel you need it. ---
