I think that did the trick (fc-cache), the graphs look more "normal"
now and I see it is loading a monospace font when I run rrdtool by
hand -

open("/usr/share/fonts/dejavu-lgc/DejaVuSansMono-Roman.ttf", O_RDONLY) = 3

Before it was opening fonts like DejaVuLGCSerif.ttf.

I also had to clear out the "RRDTool font path" in cacti's config,
If I put anything in there it switches back to a non monospace font
(not sure which one).

Thanks for the help and for the great tools over the years Tobi!
