While the plugin reduces the technical knowhow of the installation of the two servers, it still requires you to learn a bit about Grafana and write some metric queries for Influx. Everyone's Indigo setup will be different, but there are some basics that can help someone get started.
I've started a wiki document that details some example metrics (queries) that I found useful in building my own Indigo dashboard.

Please feel free to ask questions in this thread, post examples here, or add to the wiki document.
