This resource describes the metrics that are available for use in the
include_metrics field in range, record, and report
requests.
Metrics come in two varieties, metrics and histograms. We split the
metrics into the metrics or histograms attributes on the result for
historical reasons and to make parsing them more convenient.
A metric metric will contain a value of either null (if no value is
present) or a number.
A histogram metric will contain a value of either null or an array
containing an array of bins and an array of counts, ie. the x,y values of
the histogram.
