    Modifier and Type Method Description
    long count()  
    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.

    • 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

      public io.micrometer.core.instrument.distribution.HistogramSnapshot takeSnapshot()
      Specified by:
      takeSnapshot in interface io.micrometer.core.instrument.distribution.HistogramSupport
      Overrides:
      takeSnapshot in class io.micrometer.core.instrument.AbstractTimer
