Type Members

1. trait CollectionContext extends AnyRef

2. case class CompactHdrSnapshot(numberOfMeasurements: Long, compactRecords: Array[Long], unitMagnitude: Int, subBucketHalfCount: Int, subBucketHalfCountMagnitude: Int) extends Snapshot with Product with Serializable

3. trait Counter extends Instrument

4. case class CounterSnapshot(count: Long) extends Snapshot with Product with Serializable

5. case class DefaultInstrumentSettings(histogram: InstrumentSettings, minMaxCounter: InstrumentSettings, gauge: InstrumentSettings) extends Product with Serializable

6. class DefaultRefreshScheduler extends RefreshScheduler

   Default implementation of RefreshScheduler that simply uses an akka.actor.Scheduler to schedule tasks to be run in the provided ExecutionContext.

7. class DifferentialValueCollector extends CurrentValueCollector

   Helper for cases in which a gauge shouldn't store the current value of a observed value but the difference between the current observed value and the previously observed value.

8. trait Gauge extends Instrument

9. class HdrHistogram extends ModifiedAtomicHistogram with Histogram

   This implementation is meant to be used for real time data collection where data snapshots are taken often over time.

10. trait Histogram extends Instrument

11. class HistogramBackedGauge extends Gauge

12. case class InstrumentCustomSettings(lowestDiscernibleValue: Option[Long], highestTrackableValue: Option[Long], precision: Option[Int], refreshInterval: Option[FiniteDuration]) extends Product with Serializable

13. case class InstrumentFactory(configurations: Map[String, InstrumentCustomSettings], defaults: DefaultInstrumentSettings, scheduler: RefreshScheduler) extends Product with Serializable

14. case class InstrumentSettings(dynamicRange: DynamicRange, refreshInterval: Option[FiniteDuration]) extends Product with Serializable

15. trait InstrumentSnapshot extends AnyRef

16. sealed trait InstrumentType extends AnyRef

17. class LazyRefreshScheduler extends RefreshScheduler

    RefreshScheduler implementation that accumulates all the scheduled actions until it is pointed to another refresh scheduler.

18. class LongAdderCounter extends Counter

19. case class Memory(factor: Double, label: String) extends UnitOfMeasurement with Product with Serializable

    UnitOfMeasurement representing computer memory space.

20. trait MinMaxCounter extends Instrument

21. class PaddedMinMaxCounter extends MinMaxCounter

22. trait RefreshScheduler extends AnyRef

23. case class Time(factor: Double, label: String) extends UnitOfMeasurement with Product with Serializable

    UnitOfMeasurement representing time.

24. trait UnitOfMeasurement extends AnyRef

    A UnitOfMeasurement implementation describes the magnitude of a quantity being measured, such as Time and computer Memory space.
