Hi,
I want to combine data queries from two data sources (both times Prometheus) and have the SUM of both. This in principle works nicely using the Merge transformation.
However, I would need to have one label / attribute respected, which is the region. This gets lost with Merge. I tried Group By transformation, but couldn’t get it running (and would have to hardcode regions, which is something that additionally changes).
Do you have a suggestion for me how to get the sum of both results per region?
Thanks
Steffen
