Type Members

1. sealed trait BucketConfig extends AnyRef

   

   Configuration object for how a histogram's buckets should be specified

2. final case class BucketList(buckets: Vector[Int]) extends AnyVal with Product with Serializable

   

   A BucketList contains an ascending-sorted list of lower bounds to use as buckets for a histogram.

   A BucketList contains an ascending-sorted list of lower bounds to use as buckets for a histogram. A value added to a histogram will get added to the first bucket whose lower bound is less then the value.

3. class Collection extends AnyRef

   

4. class CollectionInterval extends AnyRef

   

5. trait Collector extends AnyRef

   

   Base trait required by all metric types.

6. case class CollectorConfig(intervals: Seq[FiniteDuration], baseConfig: Config, collectorDefaults: Config) extends Product with Serializable

   

   A config object passed to new event collectors in addition to their own config.

   A config object passed to new event collectors in addition to their own config.

   intervals

   The aggregation intervals configured for the MetricSystem this collection belongs to

   collectorDefaults

   a typesafe config object for collector defaults

7. trait Counter extends Collector

   

   Metrics Collector which track Long values.

   Metrics Collector which track Long values. A single Counter instance divides counter values up by tag maps and track each one independently. When they are collected and reported, all TagMaps will be reported under the same MetricAddress.

8. class DefaultHistogram extends Histogram

   

9. class DuplicateMetricException extends Exception

   

10. class FiniteDurationExpectedException extends Exception

    

11. trait Histogram extends Collector

    

    Metrics Collector which measures the distribution of values.

    Metrics Collector which measures the distribution of values. A single Histogram instance divides valuess up by TagMaps and track each one independently When they are collected and reported, all TagMaps will be reported under the same MetricAddress.

12. class IntervalAggregator extends Actor with ActorLogging

    

13. class InvalidHostAddressException extends IllegalArgumentException

    

14. class LoggerSender extends MetricSender

    

15. class LoggerSenderActor extends Actor with ActorLogging with MetricsLogger

    

    Simple sender that just prints the stats to the log

16. case class MetricAddress(components: List[String]) extends Product with Serializable

    

17. case class MetricContext(namespace: MetricAddress, collection: Collection, tags: TagMap = TagMap.Empty) extends MetricNamespace with Product with Serializable

    

18. trait MetricFormatter[T] extends AnyRef

    

19. case class MetricFragment(address: MetricAddress, tags: TagMap, value: MetricValue) extends Product with Serializable

    

20. type MetricMap = Map[MetricAddress, ValueMap]

    

21. trait MetricNamespace extends AnyRef

    

    A MetricNamespace is essentially just an address prefix and set of tags.

    A MetricNamespace is essentially just an address prefix and set of tags. It is needed when getting or creating collectors. The namespace address is prefixed onto the given address for the collector to create the full address. Tags are added to each collector under under this context.

    val subnameSpace: MetricContext = namespace / "foo" * ("a" -> "b")

22. class MetricReporter extends Actor with ActorLogging

    

23. case class MetricReporterConfig(metricSenders: Seq[MetricSender], globalTags: Option[TagGenerator] = None, filters: MetricReporterFilter = MetricReporterFilter.All, includeHostInGlobalTags: Boolean = true) extends Product with Serializable

    

    Configuration class for the metric reporter

    Configuration class for the metric reporter

    metricSenders

    A list of MetricSender instances that the reporter will use to send metrics

24. sealed trait MetricReporterFilter extends AnyRef

    

    Tells a MetricReporter how to filter its Metrics before handing off to a Sender.

25. trait MetricSender extends AnyRef

    

26. class MetricSystem extends MetricNamespace

    

    The MetricSystem provides the environment for creating metrics and is required to create collectors.

27. case class MetricSystemConfig(enabled: Boolean, name: String, systemMetrics: SystemMetricsConfig, collectorConfig: CollectorConfig) extends Product with Serializable

    

    Configuration object for a MetricSystem

    Configuration object for a MetricSystem

    enabled

    true to enable all functionality. Setting to false will effectively create a dummy system that does nothing

    name
