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()

Specified by:

count in interface io.micrometer.core.instrument.Timer

totalTime

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

Specified by:

totalTime in interface io.micrometer.core.instrument.Timer

max

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

Specified by:

max in interface io.micrometer.core.instrument.Timer

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.
