MetricBuilder

class MetricBuilder extends AnyRef

A builder class used to configure settings and metadata for metrics prior to instantiating them. Calling any of the three build methods (counter, gauge, or histogram) will cause the metric to be instantiated in the underlying StatsReceiver.

Instance Constructors

  1. new MetricBuilder(keyIndicator: Boolean = false, description: String = "No description provided", units: MetricUnit = Unspecified, role: SourceRole = NoRoleSpecified, verbosity: Verbosity = Verbosity.Default, sourceClass: Option[String] = None, name: Seq[String] = Seq(), processPath: Option[String] = None, percentiles: IndexedSeq[Double] = IndexedSeq(), statsReceiver: StatsReceiver)

    keyIndicator

    indicates whether this metric is crucial to this service (ie, an SLO metric)

    description

    human-readable description of a metric's significance

    units

    the unit associated with the metrics value (milliseconds, megabytes, requests, etc)

    role

    whether the service is playing the part of client or server regarding this metric

    verbosity

    see StatsReceiver for details

    sourceClass

    the name of the class which generated this metric (ie, com.twitter.finagle.StatsFilter)

    name

    the relative metric name which will be appended to the scope of the StatsReceiver prior to long term storage

    processPath

    a universal coordinate for the resource

    percentiles

    used to indicate buckets for histograms, to be set by the StatsReceiver

    statsReceiver

    used for the actual metric creation, set by the StatsReceiver when creating a MetricBuilder
