commented a year ago
Saw from one of the emails this morning that this isn't running
because there's no python2 on whatever system it was trying to
run on. This ports it to Python 3 (thanks, 2to3) and cleans up
the formatting (thanks, black). I tested it with a random sample
file I found lying around the internet -
https://github.com/bahamas10/node-nagios-status-parser/blob/master/status.dat
and it seems to do what it's supposed to do.
