Class CumulativeHistogramLongTaskTimer

java.lang.Object

io.micrometer.core.instrument.AbstractMeter

io.micrometer.core.instrument.internal.DefaultLongTaskTimer

io.micrometer.core.instrument.internal.CumulativeHistogramLongTaskTimer

All Implemented Interfaces:

HistogramSupport, LongTaskTimer, Meter

public class CumulativeHistogramLongTaskTimer
extends DefaultLongTaskTimer

Extends the default long task timer, making histogram counts cumulative over time.

Since:

1.5.2

Method Details

takeSnapshot

public HistogramSnapshot takeSnapshot()

Description copied from interface: HistogramSupport

Summary statistics should be published off of a single snapshot instance so that, for example, there isn't disagreement between the distribution's bucket counts because more events continue to stream in.

Specified by:

takeSnapshot in interface HistogramSupport

Overrides:

takeSnapshot in class DefaultLongTaskTimer

Returns:

A snapshot of all distribution statistics at a point in time.
