Grafana Expressions

Hello!
Sorry for my English.

I have 2 datasources of Elasticsearch.
I want to find the number (count) of documents in both data sources that have the same field value.

I believe you can accomplish what you want using the mixed datasource and then using transformations. You’ll need Grafana 7.x or higher.

Hello. How can I calculate the same values of two queries from different data sources? I already did “Merge” and “Group By” operations

I need to match the number of identical values

Have you explored Grafana’s expressions feature? It is still experimental.
