Does sysusage report an error when executed manually?

sudo /usr/local/sysusage/bin/sysusage

[cb371j]

no errors at all. debug appears to be working . for some reason it just refuses to write the values into the rrd files, even if I open them all the way with 777. permissions/ownership changes have no effect.

I just make a fresh install on an Ubuntu 18.04 and I do not have any problem. How do you get the NaN report? And does running manually /usr/local/sysusage/bin/sysusagejqgraph -d reports any error and look at the right place for rrdfiles (should be /usr/local/sysusage/rrdfiles/oe1-controller-1/)?
