Hello,

I have a pmm-server hosted on an AWS EKS cluster and exposed it on localhost, I am able to access the PMM UI as well as the /prometheus endpoint that has Single-node VictoriaMetrics.

When I am adding pmm’s service ([http://monitoring-service.pmm.svc.cluster.local/prometheus](http://monitoring-service.pmm.svc.cluster.local/prometheus)) as a data source to Grafana also hosted in the same cluster, I am getting 401 unauthorized. I had to use Chrome’s debug tools and pass cookie session to add the datasource. Is there a better way to do the authentication?

Thanks.

@skp15 I use this format `https://username:pass@pmm-server.local/` to provide un/pw when accessing PMM on CLI.

It’s not on the CLI but when I add pmm as a Prometheus endpoint datasource in Grafana UI.

Yes, I understood that you are using the PMM UI. You asked for an alternate way to provide un/pw to PMM so you could access the endpoint. The same situation is required when accessing PMM on CLI. Using the URL format I showed, you should be able to access the PMM endpoint.
