I know with latest versions we can get index size easy via the Kibana console. However, wondering it its possible to run a search in elasticsearch that comes back by volume of data by a tag e.g. for example I have app name as a tag and want to see how much filebeat data is ingest in MB consumption per app.
I understand yes you could run estimate this - but no all apps log the same e.g. some payloads are much smaller than others.
