MetricsBucketedHistogram

class MetricsBucketedHistogram extends MetricsHistogram

A MetricsHistogram that is latched such that a snapshot of the values are taken every latchPeriod and that value is returned for rest of latchPeriod. This gives pull based collectors a simple way to get consistent results.

This is safe to use from multiple threads.

    Returns an immutable snapshot of the state of the histogram right now.

    Returns an immutable snapshot of the state of the histogram right now.

    If the underlying histogram is latched or buffered, data might be slow to appear or might disappear after some time passes.

    To reread the histogram, snapshot must be called again.
