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) } }
Gives a marker that wraps the PartialFunction pf, which on execution marks the meter on an exception, and returns result of f.
Gives a marker that wraps the PartialFunction pf, which on execution marks the meter on an exception, and returns result of f.
Example usage:
class Example(val shardedDb: List[Db]) extends Instrumented { private[this] val shardExceptionMeter = metrics.meter("shard").exceptionMarkerPartialFunction private[this] val shardFunction: PartialFunction[Long,Db] = shardExceptionMeter { case id:Long => shardedDb(id.toInt % shardedDb.length) } private[this] def shard(id: Long): Db = shardFunction.applyOrElse(id,(x: Long) => shardedDb(0)) def load(id: Long) = { shard(id).load(id) } }
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 façade class for Meter.
