Grafana 4.6 on Raspberry Pi

I am running Grafana + Prometheus on a Raspberry Pi 2 to collect metrics of all my things. Unfortunately, there is no official Grafana Package for ARM so i looked into how to build it myself.

Basically you can use the Instructions on github except some minor changes. Grafana requires phantomjs to export Graphs as images but that doesn't exist for ARM as well. Usually don't need that so i decided do strip phantomjs out.

To do so, you can just remove phantomjs from yarn.lock before running yarn install:
