Setup

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. Specify your app IDs (found in the New Relic URL of an application), and define the corresponding metrics in the .erb.

newrelic_rpm.erb

<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="YOURAPPID1_rpm_throughput" data-view="Meter" data-title="RPM" data-min="0" data-max="100"></div>
</li>
<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="YOURAPPID2_rpm_throughput" data-view="Meter" data-title="RPM" data-min="0" data-max="100"></div>
</li>

newrelic_rpm.rb

require 'newrelic_api'

# Newrelic API key
key = 'ENTER YOUR KEY'

# Monitored application
app_id = ['YOURAPPID1' ,'YOURAPPID2']


# Emitted metrics:
# - rpm_apdex
# - rpm_error_rate
# - rpm_throughput
# - rpm_errors
# - rpm_response_time
# - rpm_db
# - rpm_cpu
# - rpm_memory

NewRelicApi.api_key = key

SCHEDULER.every '10s', :first_in => 0 do |job|

  newrelicapp = NewRelicApi::Account.find(:first).applications.select{|app| app.id.to_s == app_id }.first

    newrelicapp.threshold_values.each do |v|
        puts v.metric_value
        send_event(newrelicapp.id + "_rpm_" + v.name.downcase.gsub(/ /, '_'), { value: v.metric_value })
    end

end

Hi Erik,

I get this error when using your NR dash:
scheduler caught exception:
undefined method threshold_values' for nil:NilClass /var/www/dashboard_publicdash1/jobs/newrelic_rpm.rb:26:inblock in <top (required)>'

Tnx
Nico

My fork contains a fix for that error as well as a bit of a refactor: newrelic_rpm.
