module RPMContrib::Instrumentation::Camping

Instrumentation for Camping

To instrument all controllers do the following:

  1. Add require ‘rpm_contrib’ after loading camping.

  2. Add an include at the end of your main Camping app module

  3. Run the following command to get the NewRelic license key to use: heroku config -all

  4. Create a newrelic.yml under the /config folder with the following content:

    common: &default_settings

    license_key: 'PASTE THE VALUE OF NEW_RELIC_LICENSE_KEY HERE'
app_name: PASTE THE NAME OF YOUR CAMPING APP HERE
monitor_mode: true

    production:

    <<: *default_settings

Camping code example:

require "rpm_contrib"

Camping.goes :NewRelicCampingTest

module NewRelicCampingTest
  # your code

  include RPMContrib::Instrumentation::Camping

end
