Tiny proxy to enforce a filter on InfluxQL queries.
Enable the InfluxDB HTTP API. For this example, we'll assume it is reachable at influx-node:8086.
To scope a Grafana organization to the client named test-client, configure an InfluxDB datasource to hit the proxy (default listening port: 9094).
Do not allow the client to directly hit it. Every request must use the Grafana proxy first, which ensures the client is correctly authenticated.
Append to the datasource URL the client name, making it in our case http://localhost:9094/test-client.
Now, every request made through Grafana will append the correct filters.
