Hello, Currently I have a 3 node ElasticSearch cluster. Each node is a RHEL VM with 16 gig RAM. The basic config is:
- All nodes can be master and are data nodes. - 3 shards and 1 replica - 6 different indexes I'm starting to run into issues of ElasticSearch bogging down on searches and is completely freezing sometimes at night. I've dedicated 9 gig to heap size and it says i'm using ~60% of the heap RAM and about 70% of the overall heap. So even though I'm using quite a bit of the heap, I'm not maxed out. I've attached a screenshot of the exact stats from Elastic HQ. I'm averaging around 10,000 events/sec coming into the cluster from 6 different Logstash instances on another server. My question is what can I do to help the stability and speed of my cluster. Currently I'm having issues with 1 node going down and it taking everything else down. The HA portion isn't working very well. I'm debating about either adding 1 more node with the exact same stats or adding 2 more smaller VMs that will act as master nodes only. I didn't know which one was recommended or where I would get the biggest bang for the buck. Any information would be greatly appreciated.
