Newrelic: Cloudwatch Plugin with AWS Autoscaling Groups responses being returned nil?

Am using the Cloudwatch plugin for Newrelic found here: https://github.com/brettcave/newrelic_aws_cloudwatch_plugin

For some reason though, my responses are all being returned nil: 

[2014-09-19 12:43:15 UTC] INFO: Retrieving statistics: {:namespace=>"AWS/EC2", :metric_name=>"DiskWriteOps", :statistic=>"Sum", :unit=>"Count", :dimension=>{:name=>"AutoScalingGroupName", :value=>"AUTOSCALER-BackendGroup-19N8SYDEIPGYV"}, :period=>60, :start_time=>"2014-09-19T12:41:15Z", :component_name=>"AUTOSCALER-BackendGroup-19N8SYDEIPGYV", :end_time=>"2014-09-19T12:41:45Z", :dimensions=>[{:name=>"AutoScalingGroupName", :value=>"AUTOSCALER-BackendGroup-19N8SYDEIPGYV"}]}
[2014-09-19 12:43:15 UTC] INFO: Retrieved statistics: {:datapoints=>[], :label=>"DiskWriteOps", :response_metadata=>{:request_id=>"3cb0c8a6-3ffa-11e4-aea1-91b035de76f7"}}
[2014-09-19 12:43:15 UTC] DEBUG: metric_name: DiskWriteOps, statistic: Sum, unit: Count, response: nil

This is the code as described in the above link, which conforms to the aws cloudwatch list-metrics --namespace "AWS/EC2" command output.

module NewRelicAWS
 module Collectors
    class ASG < Base
      def initialize(access_key, secret_key, region, options)
        super(access_key, secret_key, region, options)
        @asg = AWS::AutoScaling.new(
          :access_key_id => @aws_access_key,
          :secret_access_key => @aws_secret_key,
          :region => @aws_region
        )
      end


  def groups
    @asg.groups
  end

  def metric_list
    [
      ["CPUUtilization", "Average", "Percent"],
      ["DiskReadOps", "Sum", "Count"],
      ["DiskWriteOps", "Sum", "Count"],
      ["DiskWriteBytes" , "Sum", "Bytes"],
      ["NetworkIn", "Sum", "Bytes"],
      ["NetworkOut", "Sum", "Bytes"]
    ]
  end

  def collect
    data_points = []
    groups.each do |group|
      metric_list.each do |(metric_name, statistic, unit)|
        data_point = get_data_point(
          :namespace   => "AWS/EC2",
          :metric_name => metric_name,
          :statistic   => statistic,
          :unit        => unit,
          :dimension   => {
            :name  => "AutoScalingGroupName",
            :value => group.name
          },
          :period => 60,
          :start_time => (Time.now.utc-120).iso8601,
          :component_name => group.name
        )
        NewRelic::PlatformLogger.debug("metric_name: #{metric_name}, statistic: #{statistic}, unit: #{unit}, response: #{data_point.inspect}")
        unless data_point.nil?
          data_points << data_point
        end
      end
    end
    data_points
  end
end
end
end

This is nearly identical to the EC2 plugin, though the EC2 plugin works. Any idea what could be wrong?

Thanks in advance.

Does the official New Relic plugin work for you? https://github.com/newrelic-platform/newrelic_aws_cloudwatch_plugin
