I have a index with source field. It can have two values. For ex: "sourceA" & "sourceB".
I am trying to create to metric aggregation panels with source filter.
It is possible to create metric aggregation with single filter source : "source A" or "source B" and get the respective count of documents.
I want to create a metric aggregation visualization with difference in the count of documents with souce A and source B.
Could you please help?
