Hello all
i just stumbled upon this blog entry: Forecasting metrics - A look into the future
I followed the install instructions and although it says “not production ready”, can clearly say: woooooooooohoooooooooooooooo 
Works like a charm and i only can encourage everyone to try it out.
We have it running on 1.6p14 CEE, Ubuntu 18.04, our production site, where i installed it “accidentally”
