This api provides an efficient and thread-safe way of loggin metrics in a multi-thread environment. It is easy to use and very flexible. By plugging in different Sink classes metrics can be logged to various back-end targets.

Create an StandardRequestEmitter object with root MetricDimension and a Sink object. You are ready to log your metrics. MetricDimension is used as identifier of metrics and also can be used to log event messages. The various types of metrics may be logged using one of the following methods: emit, emitDuration and emitSpan. By calling complete all the metrics you logged to the StandardRequestEmitter object will be pushed to the back-end of Sink class.
