Comment 2 for bug 1480442

i think this is a side effect of removing pipeline from polling agent -- the pipeline functionality doesn't actually apply anymore. if i put this in context of current pipeline:

sources:
    - name: meter_source
      interval: 600
      meters:
          - "*"
      sinks:
          - meter_sink
    - name: cpu_source
      interval: 600
      meters:
          - "cpu"
      sinks:
          - cpu_sink
sinks:
    - name: meter_sink
      transformers:
      publishers:
          - notifier://
    - name: cpu_sink
      transformers:
          - name: "rate_of_change"
            parameters:
                target:
                    name: "cpu_util"
                    unit: "%"
                    type: "gauge"
                    scale: "100.0 / (10**9 * (resource_metadata.cpu_number or 1))"
      publishers:
          - notifier://

this will poll cpu twice. i don't need to poll twice. i just want the cpu meter and i want the cpu_util value i can derive from it.
