Actually, I have a problem with my ElasticStack. I have crashes on my main elastic search when i ask in grafana dashboards for more than 6 days.
The memory and CPU is high but I
ve increased the CPU and mem unsuccessfully. In logs Ive seen some error about GC and I need help to locate the issue for queries with a weeks time.
Now, I have 5 servers Elasticsearch with 4 CPU, 15GB mem(7G for heap)
"active_primary_shards" : 467
"active_shards" : 468
Maybe, I need to decrease the primary shards...
