> Issue Type: Task
> Components: ambari-metrics
> Affects Versions: 2.0.0

> Current behavior:
> We store the difference between two points if the metric is a counter without
> dividing by the time difference (Assumes fixed sampling frequency, 10 seconds
> for Hadoop daemons). This is similar to the Ganglia sink implementation.
> Expected behavior:
> - Store raw data with type = COUNTER and provide aggregate function called
> ._rate to calculate rate on demand.
> - We need to make sure type attribute on the METRIC_RECORD data capture
> COUNTER / GAUGE. The HadoopMetricsSink needs to change to send this value.
