Javadoc
Sets the supplier that should be used to create the request-size and response-size Histogram metrics. You
might want to set this in order to change the
Reservoir type used by the histograms to a
SlidingTimeWindowReservoir with the sliding window time values that match your reporter's update frequency.
i.e. if you passed in a supplier like this:
() -> new Histogram(new SlidingTimeWindowReservoir(10L, TimeUnit.SECONDS)) then the request-size and
response-size histograms generated would always give you data for *only* the 10 seconds previous to whenever
you requested the data. This can be null - if it is null then
#DEFAULT_REQUEST_AND_RESPONSE_SIZE_HISTOGRAM_SUPPLIER will be used.
