Hi, I am trying to replace a ASUS ChromeBit which we used to show our Grafana graphs (a playlist of multiple dashboards). But I can’t get it to draw the graphs in Chromium. I am currently running Raspbian Stretch with X. Does anyone know a fix for this? Is it because the JS behind the dashboard…

Rendering might be slow on Raspberry PI if you have a lot of graphs/re-render quite often, but it should definitely work. Are there any errors in your log file? check /var/log/grafana/ Or in the Chromium developer console? How did you install Grafana?

It doesn’t render at ALL. It do come up with some jquery stuff in the console in Chromium. Grafana is hosted elsewhere i’m just opening the GUI on the raspberry pi.

Ah. Are there any errors in the chromium dev console? and if so, could you copy them or take a screenshot?

It’s saying: Uncaught TypeError: Cannot read property ‘save’ of null at J (jquery.flat.js.3048) I have set the Raspberry PI GPU memory to 256.

side note: We run Grafana v5.3.1 (08c7908)

Yes, default settings for GPU memory is 64, i have tried all settings for that. I have even tried forcing chromium to use EGL. I have also tried Firefox, we are currently showing our dashboards on a Chromebit which works perfectly but they have died so easily so thats why we are researching the ma…

I have used Raspberry Pi 2B+ devices to with Grafana in the past so I’d be really surprised if it wasn’t possible to get it working with the 3rd gen. Just as a reference, have you tried going to play.grafana.org with the Pi?

I’ve just tested it out and it doesn’t render. I have tried with 64MB and 128MB gpu memory.

Btw, is there anything in the Chromium application log?

Not sure what would cause that but will ask if any of my colleagues have experience with similar problems. I presume you have tried running chromium with default settings as well? (128mb of GPU RAM)
