Morning team.

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 I`ve 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...

BR

Yea, that are a lot of shards. Try to merge or delte them. Look here: [Link](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster).  
Also, why grafana and not kibana?

It is a bad "habit" in my company. I`m triying to change from Grafana to Kibana.

Thnx.

Trying to merge the shards... nope.  
I will try to delete some shards because the merge has not solved the issue with the mem.

How large are your shards and indices?
