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.

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 of pf (for the cases it is defined).

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
}
