For those who would like to use the Grafana dashboard app with PRTG, I've created a plugin for PRTG. With Grafana, you can create elegant and informative dashboards with your PRTG data. Great for "heads-up" displays or for getting a quick glance at the status of your sharepoint farm.
This is not intended to replace any PRTG functionality.
You can download the plugin from Github and I encourage feedback and contributions :)
