Detecting Ruby processes by parameter, RegEx in `namemapping` not working

[wenfei3]

well, I tried to use yaml config file when start the process_exporter,

process_names:
  - comm:
    - ruby
  #- cmdline:
  #  - ^unicorn\s.+batman.+alpha.rb\s.+

and there is some logs for the curl "http://localhost:9256/metrics"

I think these are my monitor data,but I don't know how to rename groupname,and I had not found any ways to rename groupname in the README.md, could you give me a hand?
by the way, how to use the cmdline?I tried just like above note,but it didn't work.
thank you very much!
