I'm implementing data analysis through ELK,
To find the count of a value that contains a specific string in a field
I'm trying to use Visualize's JSON Input feature,
I can not find what kind of format I should enter.
If you can check it, please answer it.
if I understand you correctly, you should be able to achieve that without using JSON input but with a combination of the count metric and a filters bucket aggregation.
