I'm using Grafana for visualization.
the problem is, If I make too many graphs on single dashboard, It caused to ES freeze - and of course, I can't insert any data to ES.
the only solution for this problem that I found, is release ES cache...
To solve this problem, I added 2 more ES data node, but have no luck
If I can make Grafana to search on replica nodes only, I think it'll be helpful - at least, primary shards will working, isn't it?
but I can't find how to connect to replicas. Is there any guide for this?
thanks for help.
