Embedding Grafana charts not working

Replace this template with your information

I’m trying to enable Grafana graphs integration in GitLab and I’m having some issues. I followed GitLab’s docs and I setup the integration (Grafana URL and API token). I then paste the URL into the issue and post it. But the graph doesn’t render.

In the console, I get the following error: Failed to load resource: the server responded with a status of 422 ()

Looking in GitLab’s production log file, I get the error:
“method”: “GET”,
“path”: “/group/project/-/grafana/metrics_dashboard”,
“format”: “json”,
“controller”: “Projects::GrafanaApiController”,
“action”: “metrics_dashboard”,

“queue_duration”: 3.24,
“response”: “{“message”:“Datasource name not found”,“status”:“error”}”,
“cpu_s”: 0.023109362000468536

Looking at the logs on the Grafana server, I don’t see a request getting there, so I guess it’s canceled inside GitLab. I don’t know what Datasource name not found means and what datasource it wants.

I’m running Grafana on another server, but I double checked and GitLab instance does have access to Grafana. I’m running GitLab 12.8.1.

Can anyone shed some light on this?

I would also be interested in how to troubleshoot this?

My production.log does not show anything suspicious:
