InstrumentedBuilder

The mixin trait for creating a class which is instrumented with metrics.

Use it as follows:

object Application {
  // The application wide metrics registry.
  val metricRegistry = new com.codahale.metrics.MetricRegistry()
}
trait Instrumented extends InstrumentedBuilder {
  val metricRegistry = Application.metricRegistry
}

class Example(db: Database) extends Instrumented {
  private[this] val loading = metrics.timer("loading")

  def loadStuff(): Seq[Row] = loading.time {
    db.fetchRows()
  }
}

It is also possible to override the metric base name. For example:

class Example(db: Database) extends Instrumented {
override lazy val metricBaseName = MetricName("Overridden.Base.Name")
private[this] val loading = metrics.timer("loading")

def loadStuff(): Seq[Row] = loading.time {
  db.fetchRows()
}
}
