    text
    copied!<p>I am developing a Ruby gem that I would like to add NewRelic monitoring to. The gem is used in a script that is run as a daemon and monitored by <code>bluepill</code>. I followed "<a href="https://docs.newrelic.com/docs/ruby/monitoring-ruby-background-processes-and-daemons" rel="nofollow">Monitoring Ruby background processes and daemons</a>" to get started. </p> <p>I confirmed the gem is establishing a connection with NewRelic as the application shows up in my portal there, however, there is no transaction traces or any metrics breakdown of the code being invoked.</p> <p>Here's the "entry" point of my gem as I tried to manually start the agent around the invoking method:</p> <pre><code>require 'fms/parser/version' require 'fms/parser/core' require 'fms/parser/env' require 'mongoid' ENV['NRCONFIG'] ||= File.dirname(__FILE__) + '/../newrelic.yml' require 'newrelic_rpm' module Fms module Parser def self.prepare_parse(filename) ::NewRelic::Agent.manual_start Mongoid.load!("#{File.dirname(__FILE__)}/../mongoid.yml", :development) Core.prepare_parse(filename) ::NewRelic::Agent.shutdown end end end </code></pre> <p>I also tried adding this into the module:</p> <pre><code> class &lt;&lt; self include ::NewRelic::Agent::Instrumentation::ControllerInstrumentation add_transaction_tracer :prepare_parse, :category =&gt; :task end </code></pre> <p>I'm not entirely sure what else I can do. I confirmed the agent is able to communicate with the server and transaction traces are enabled. Nothing shows up in the background application tab either. </p> <p>This is the most useful information I've gotten from the agent log so far:</p> <pre><code>[12/23/13 21:21:03 +0000 apivm (7819)] INFO : Environment: development [12/23/13 21:21:03 +0000 apivm (7819)] INFO : No known dispatcher detected. [12/23/13 21:21:03 +0000 apivm (7819)] INFO : Application: MY-APP [12/23/13 21:21:03 +0000 apivm (7819)] INFO : Installing Net instrumentation [12/23/13 21:21:03 +0000 apivm (7819)] INFO : Finished instrumentation [12/23/13 21:21:04 +0000 apivm (7819)] INFO : Reporting to: https://rpm.newrelic.com/[MASKED_ACCOUNT_NUMBER] [12/23/13 22:12:06 +0000 apivm (7819)] INFO : Starting the New Relic agent in "development" environment. [12/23/13 22:12:06 +0000 apivm (7819)] INFO : To prevent agent startup add a NEWRELIC_ENABLE=false environment variable or modify the "development" section of your newrelic.yml. [12/23/13 22:12:06 +0000 apivm (7819)] INFO : Reading configuration from /var/lib/gems/1.9.1/gems/fms-parser-0.0.6/lib/fms/../newrelic.yml [12/23/13 22:12:06 +0000 apivm (7819)] INFO : Starting Agent shutdown </code></pre> <p>The only thing that's really concerning here is "No known dispatcher detected".</p> <p>Is what I'm trying to do possible?</p>
