Grafana Proxy

The technical documentation of the grafana-proxy microservice, which proxies request from Grafana to the backend services.

This microservice is still in development and is not considered stable for production use

How it works

The grafana-proxy microservice serves an HTTP REST endpoint located at /api/v1/{service}/{data}. The service parameter specifies the backend service to which the request should be proxied, like factoryinput or factoryinsight. The data parameter specifies the API endpoint to forward to the backend service. The body of the HTTP request is used as the payload for the proxied request.
