I have graylog 2.3 installed on red hat
I have elasticsearch 4 shards no replicas 2.0
I have mongodb 3.0
My machine: 64Go RAM
12 processors CPU
Elasticsearch heap: 24go
Java heap: 15Go
Everything is installed on a single machine.
My problem is that all memory is not consumed and there is always 47 Go memory unused
I can only get 200msg/s before graylog buffers the messages
Could you tell me if there is something I could do to make graylog use all memory?
