I have an elasticsearch cluster with around 4Bn docs. I am trying to do some analysis to get insights in our document sizes. For this I am using the mapper-size plugin to enable the "_size" field. Now after i build the es indices, i am seeing this field under "stored_fields". However for some reason kibana doesn't pick this field by default (atleast not that i know of). Is there a way to enable this field in kibana ? I know stored_fields are hidden, so i just want a way expose it to kibana so as to make my analysis.
Thanks for your help in advance.
Edit : ES v 5.4.3
KIbana V 5.4.3
