I apologize for my beginner question.
I've created an index in elasticstack with contains all my servers and includes fields for server function, installed and used memory, example below:
name, function, installed memory, used memory
server1, Database, 512, 128
server2, web. 512, 64
server3, web, 512, 512
In Kibana 5.3, how do I display in tabular form the sum of installed memory, sum of used memory and % used memory by server function?
I've created Data Table Visualization which displays the sum of installed and used memory by server function but I can't see how to add the sum of used memory as a percentange of the sum of the installed memory.
Thanks in advance
