Any interest in allow rack.processes metric submission to be disabled?

Hi,

I'm curious if you'd be willing to accept a PR to disable the rack.processes metric.

I use this gem through the awesome librato-rails gem, and i disable all of the fancy suites that come with the librato-rails gem. I was surprised to find that even with those suites disabled, this metric still comes through.

So, would you be interested in some sort of configuration option to disable that metric submission? Specifically, this is the relevant line:

librato-rack/lib/librato/rack/tracker.rb

Line 128 in 93cfcbe

queue.add 'rack.processes' => { value: 1, tags: tags }

Thanks. I appreciate the library and your time!

Hi @samandmoore

Thanks for the issue. It seems reasonable to allow rack.processes to be configurable as well.

I would recommend making the metric part of the existing rack metric suite: https://github.com/librato/librato-rack#metric-suites

At a quick glance, you should be able to handle it like this:

if suite_enabled?(:rack)
  queue.add 'rack.processes' => { value: 1, tags: tags }
end
