Method Detail

recordNonNegative

protected void recordNonNegative(long amount,
                                 java.util.concurrent.TimeUnit unit)

Specified by:

recordNonNegative in class io.micrometer.core.instrument.AbstractTimer

count

public long count()

totalTime

public double totalTime(java.util.concurrent.TimeUnit unit)

max

public double max(java.util.concurrent.TimeUnit unit)

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
