If you look picture no.1 my server have 64G and used 39G. Container elasticsearch and logstash use like 2.2G, docker image 3.4G = 5.6 G. Then the volume use like 30.7 G.

Meanwhile, if i check my index size at index management, picture no.2 . Size of the index not more than \< 20G, if I quick calculate. What make it so large almost two size of the original size? cause by json original document that I need to disable? or there's a cache?

ps : Im not running anything except linux os, elasticsearch and logstash container.
