Add the following gems to your Gemfile:
gem 'activeresource'
gem 'newrelic_api'
Update your bundle:
bundle
Put the newrelic_rpm.rb to jobs/newrelic_rpm.rb and configure your API key and Application name.
Finally, choose a metric (see "Emitted metrics" jobs/newrelic_rpm.rb) you want to show on the dashboard and add corresponding HTML code. For example, the code below shows Newrelic Throughput (requests/minute) on the scale of 100. Adjust the scale based on your application usage.
| <li data-row="1" data-col="1" data-sizex="1" data-sizey="1"> | |
| <div data-id="rpm_throughput" data-view="Meter" data-title="RPM" data-min="0" data-max="100"></div> | |
| </li> |
| require 'newrelic_api' | |
| # Newrelic API key | |
| key = 'ENTER YOUR KEY' | |
| # Emitted metrics: | |
| # - rpm_apdex | |
| # - rpm_error_rate | |
| # - rpm_throughput | |
| # - rpm_errors | |
| # - rpm_response_time | |
| # - rpm_db | |
| # - rpm_cpu | |
| # - rpm_memory | |
