Abstract Value Members

  1. abstract def addGauge(name: String*)(f: ⇒ Float): Gauge

    Add the function f as a gauge with the given name.

    Add the function f as a gauge with the given name.

    The returned gauge value is only weakly referenced by the StatsReceiver, and if garbage collected will eventually cease to be a part of this measurement: thus, it needs to be retained by the caller. Or put another way, the measurement is only guaranteed to exist as long as there exists a strong reference to the returned gauge and typically should be stored in a member variable.

    Measurements under the same name are added together.

    See also

    java.lang.ref.WeakReference

    StatsReceiver.provideGauge when there is not a good location to store the returned gauge that can give the desired lifecycle.

  2. abstract def counter(name: String*): Counter

    Get a counter with the given name.

  3. abstract val repr: AnyRef

    Specifies the representative receiver.

    Specifies the representative receiver. This is in order to expose an object we can use for comparison so that global stats are only reported once per receiver.

  4. abstract def stat(name: String*): Stat

    Get a stat with the given name.

    Get a counter with the given name.

    This method is a convenience for Java programs, but is no longer needed because StatsReceivers.counter is usable from java.

    Accurately indicates if this is a NullStatsReceiver.

    Accurately indicates if this is a NullStatsReceiver. Because equality is not forwarded via scala.Proxy, this is helpful to check for a NullStatsReceiver.

  17. def provideGauge(name: String*)(f: ⇒ Float): Unit

    Register a function f as a gauge with the given name that has a lifecycle with no end.

    Register a function f as a gauge with the given name that has a lifecycle with no end.

    This measurement exists in perpetuity.

    Measurements under the same name are added together.

    See also

    StatsReceiver.addGauge if you can properly control the lifecycle of the returned gauge.

  18. final def scope(namespaces: String*): StatsReceiver

    Prepend namespace and namespaces to the names of the returned StatsReceiver.

    Prepend namespace and namespaces to the names of the returned StatsReceiver.

    For example:

    statsReceiver.scope("client", "backend", "pool").counter("adds")

    will generate a counter named /client/backend/pool/adds.

    Annotations
    @varargs()
  19. def scope(namespace: String): StatsReceiver

    Prepend namespace to the names of the returned StatsReceiver.

    Prepend namespace to the names of the returned StatsReceiver.

    For example:

    statsReceiver.scope("client").counter("adds")
statsReceiver.scope("client").scope("backend").counter("adds")

    will generate counters named /client/adds and /client/backend/adds.

  20. def scopeSuffix(suffix: String): StatsReceiver

    Prepend a suffix value to the next scope.

    Prepend a suffix value to the next scope.

    For example:

    statsReceiver.scopeSuffix("toto").scope("client").counter("adds")

    will generate a counter named /client/toto/adds.

  21. def stat0(name: String): Stat

    Get a stat with the given name.

    Get a stat with the given name. This method is a convenience for Java programs, but is no longer needed because StatsReceivers.counter is usable from java.
