Hello, I am performing Elastic rollups on an index with the following streaming documents and fields. Rollup is on Field 1: Field1 Field2 doc1 1200 a doc2 1200 b doc3 1200 c doc4 1100 d doc5 1100 e doc6 1100 f after rollup I get: 1200 3 1100 3 I am trying to figure out a best way to maintain a running count of all documents in a new field called 'Total', so my result should look something like: Field1 count 1200 3 1100 3 'Total' 6 I know there are several possibilities to accomplish this, including using logstash, elasticsearch, kibana, but what would be the best simple approach? Can I maintain a counter in logstash pipeline for streaming data that arrives a minute apart? any other ideas? Thank you for any insights! ---
