public interface Timer extends Metered, Sampling
Meter.
See SimpleTimer for a lightweight alternative that only tracks elapsed time duration and count.
The timer measures duration in nanoseconds.| Modifier and Type | Interface and Description |

getCount()
Returns the number of events which have been marked.

java.time.Duration |
getElapsedTime()
Returns the total elapsed timing durations of all completed timing events that are recorded with
update(Duration). |

getFifteenMinuteRate()
Returns the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the
meter was created.

double |
getFiveMinuteRate()
Returns the five-minute exponentially-weighted moving average rate at which events have occurred since the meter
was created.
|
double |
getMeanRate()
Returns the mean rate at which events have occurred since the meter was created.
|
double |
getOneMinuteRate()
Returns the one-minute exponentially-weighted moving average rate at which events have occurred since the meter
was created.

Snapshot |
getSnapshot()
Returns a snapshot of the values.
