Thanks for the detailed bug report. Version 0.3.1+ contain a lot of new changes and should have been labelled pre-release (they are now). One issue I identified is that there were some /proc//status fields I depended upon that were only introduced in more recent kernels. I would definitely expect them to be present in kernel 4.17 though, so I'm not sure what's happening on your system.
Probably there's something else wrongheaded that I'm doing with the status file. For example, because I expect the Vm* fields to be present and treat it as an error if they aren't, kernel processes are failing to be scraped. I haven't decided exactly how I want to deal with that situation, but I will address it before I issue a stable release. I'll consider adding some debugging facilities as well.

I've just tested the 0.3.2 release, and it gives a successful scrape on my system, so I'll close this off. Thanks for your work on this exporter!
I've attached the scrape output (metrics.txt) and included some /proc snippets below, in case it can be used to add a unit test.
