Configuring non Rails tracers.

[whithajess]

I am struggling to work out how I can recreate the same:

Rails.configuration.datadog_trace =
  {
    # may depend by your conditional env
    enabled: false
  }

For a non Rails app when adding something like the Rack Trace Middleware you can do:

 Datadog::Contrib::Rack::TraceMiddleware, enabled: ['test','development'].exclude?(ENV['RACK_ENV'])

UPDATE: this doesn't actually work either ^

but when adding Datadog::Monkey.patch_module(:active_record) there is no option to disable this means when running in test or development modes you get a whole bunch of:

E, [2017-06-16T11:28:51.774635 #92936] ERROR -- ddtrace: [ddtrace] (.rvm/gems/ruby-2.3.3/gems/ddtrace-0.7.2/lib/ddtrace/transport.rb:73:in `rescue in post') Failed to open TCP connection to localhost:8126 (Connection refused - connect(2) for "localhost" port 8126)

If it is documented somewhere I haven't been able to find it.

Found you can just set Datadog.tracer.configure(enabled: ['test','development'].exclude?(ENV['RACK_ENV'])) will first patch documentation to make this clear before closing this.

Indeed, using Datadog.trace.configure is the way to go here. Thanks for reporting this.

Should we replace the configuration on datadog-tracer.rb file with Datadog.tracer.configure(enabled: ['test','development'].exclude? ?
