Sending additional headers to the remote write URL

[luvpreetsingh]

Hi,

I am trying to send metrics from grafana-agent to grafana mimir. I will be using multiple clusters so I will use multiple tenants. To do so, I will have to add a header while sending the metrics to mimir.

The header will be X-Scope-OrgID and the value will be staging or production.

I am using the grafana-agent-operator. The option to remote write metrics can be configured using the MetricInstance. Here is the link to the Docs for that.

The thing is, I don't see any option to add any headers while sending metrics to the remote URL. The only option is to add basicAuth.

How can I do it?

Hmm, I just added the headers block and appended the headers and looks like it is adding the headers to the requests.

It is just lacking in the documentation

I did like this

    headers:
      X-Scope-OrgID: staging-kube
    basicAuth:
      username:
        name: grafana-agent-mimir-auth
        key: username
      password:
        name: grafana-agent-mimir-auth
        key: password
