      • histogramCounts

        public io.micrometer.core.instrument.distribution.CountAtBucket[] histogramCounts()
        For Prometheus we cannot use the histogram counts from HistogramSnapshot, as it is based on a rolling histogram. Prometheus requires a histogram that accumulates values over the lifetime of the app.
        Returns:
        Cumulative histogram buckets.

      • takeSnapshot

        Specified by:

        Overrides:
        takeSnapshot in class io.micrometer.core.instrument.AbstractDistributionSummary
