This is a advanced node state screenshot of one node.

One node have 32GB of memory and 15.8GB of heap used at the screenshot time.

Graphs says lucene total is 2.7GB and elasticsearch taken up 1.4GB.

Now I can say.  
2.7(lucene)GB + ES index(1.4) + What(11GB) = 15.8GB

I wander which objects taken up the left 11GB.  
Could you please tell me other memory comsuers?

how can I devide the memory usage in detail?
