Not sure if you've investigated further. http://stackoverflow.com/questions/7422818/railtie-inititalizer-not-running-in-plugin

First of all, nice work with this project.

I've been experimenting with it and so far it looks good.

I would like to know/suggest if there's any plan on monitoring rake tasks (or background jobs). This would be very useful for the non standard Rails app.

I would be willing to help if you have any plans to work with this.

Right now we can track specific hosts, but not split out by a specific app running on a host (maybe unicorn and sidekiq on same server). Lets add app ids (uuid?) to track

It is close enough in semantics. See specification.md

Rails 4.2.8 - Ruby 2.2.6 - Passenger 5.1

All of the partials included through 'render' throw this error in production:
undefined method `path_parameters' for nil:NilClass

The stack traces do not offer much insight. They only list from the controller to the view file and end on render lines like this:

= render partial: 'data_mapper'

I believe the error comes from lines 10 and 11 in this file:
https://github.com/randy-girard/app_perf_rpm/blob/704f3c9d618c6370feef9ec232e60dbe5c96919d/lib/app_perf_rpm/instruments/action_view.rb

The app-perf host is working quite well. It seems to update much faster than NewRelic. Not quite sure why I am experiencing this error.

Issue

When running Agent for various non-production use cases like where the AppPerf server isn't available or running specs, the agent should be shouldn't start and try to send data. When worker can't connect the following errors occur:

#<Errno::ECONNREFUSED: Connection refused - connect(2) for "localhost" port 5000>
E, [2017-04-05T19:38:41.968976 #48940] ERROR -- :
["/home/ubuntu/.rvm/rubies/ruby-2.2.6/lib/ruby/2.2.0/net/http.rb:879:in

Question/Suggestion:

Add Configuration option or ENV var to disable agent. APP_PERF_DISABLE for example. I'll look into making a PR for above, unless you disagree with approach.

Rails can provide route in form of Controller#Action and Sinatra in form of GET /some/path/:id
