How to use a custom GCP trace scope (multi-project) with Grafana's Google Cloud Trace datasource?

I’m using Grafana OSS v12.2.1 with the Google Cloud Trace datasource. I’ve connected a GCP project successfully and can see traces in Explore.

In GCP, I’ve created a custom trace scope that includes multiple projects and set it as my default trace scope. However, Grafana continues to pull traces only from the single default project scope — the custom multi-project scope is ignored, even though it’s marked as default in GCP.

Is there a way to make Grafana’s Google Cloud Trace datasource respect the custom default trace scope, so I can query traces across multiple projects in the Explore tab?

Do you have configured Project List Filter and latest plugin version?

Hi Jangaraj,

I have already configured this. It does allow me to pull traces from multiple projects, but it only loads each project’s own default trace scope. The custom trace scope I created in GCP (spanning multiple projects) is still not being used.

Can someone pls check this
