class Meter extends AnyRef
A Scala facade class for DropwizardMeter.
Example usage:
class Example(val db: Db) extends Instrumented { private[this] val rowsLoadedMeter = metrics.meter("rowsLoaded") def load(id: Long): Seq[Row] = { val rows = db.load(id) rowsLoaded.mark(rows.size) rows } }

- def exceptionMarker: AnyRef { def apply[A](f: => A): A }
Gives a marker that runs f, marks the meter on an exception, and returns result of f.
Gives a marker that runs f, marks the meter on an exception, and returns result of f.
Example usage:
class Example(val db: Db) extends Instrumented { private[this] val loadExceptionMeter = metrics.meter("load").exceptionMarker def load(id: Long) = loadExceptionMeter { db.load(id) } }
- def exceptionMarkerPF: AnyRef { def apply[A, B](pf: PartialFunction[A,B]): PartialFunction[A,B] }
Converts partial function
pf
into a side-effecting partial function that meters thrown exceptions for every invocation ofpf
(for the cases it is defined).Converts partial function
pf
into a side-effecting partial function that meters thrown exceptions for every invocation ofpf
(for the cases it is defined). The result is passed unchanged.Example usage:
class Example extends Instrumented { val isEven: PartialFunction[Int, String] = { case x if x % 2 == 0 => x+" is even" case 5 => throw new IllegalArgumentException("5 is unlucky") } val isEvenExceptionMeter = metrics.meter("isEvenExceptions") val meteredIsEven: PartialFunction[Int, String] = isEvenExceptionMeter.exceptionMarkerPF(isEven) val sample = 1 to 10 sample collect meteredIsEven // the meter counts 1 exception }
- def fifteenMinuteRate: Double
The fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
The fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
This rate has the same exponential decay factor as the fifteen-minute load average in the top Unix command.
