The number of events which have been marked.
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) } }
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).
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).
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 }
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.
The five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
The five-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 five-minute load average in the top Unix command.
Marks the occurrence of a given number of events.
Marks the occurrence of an event.
The mean rate at which events have occurred since the meter was created.
The one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
The one-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 one-minute load average in the top Unix command.
A Scala facade class for DropwizardMeter.
