Grafana Expressions

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.

Hi @frostwar,

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

check out this thread
and this thread

Grafana docs on transformation types

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.

It’s not worked for me
