  Adds a Scala layer on the official [Prometheus Java client](https://github.com/prometheus/client_java) library.

  Adds a Scala layer on the official [Prometheus Java client](https://github.com/prometheus/client_java) library. The purpose is to elevate on the capabilities of the Scala language and provide more fitting constructs. E.g. lambdas from Java don't translate very well into Scala, so this library provides functional approaches to where the original library uses lambdas. Also for time/latency/gauge measurement purposes this library provides means to measure Futures.

  E.g. measuring the time spent in a function block.

  val requestLatency:Histogram = ...
  val result = requestLatency.measure{
    // Your code here.
  }

  Or measuring the time to execute a future provided as result by a function. The code snippet below will measure the time from invoking the function block to when the future is completed

  val requestLatency:Histogram = ...
  val f:Future[_] = requestLatency.measureAsync{
    Future {
      // Your code here.
    }
  }

  Enriches the Summary class with new functions.

  Enriches the Summary class with new functions.

  The unit used to report latency/time measurements is decided by an implicitly available TimeUnit.
  If no TimeUnit is in scope it defaults to TimeUnit.SECONDS.
  One can either declare an implicit value:

  implicit val defaultUnit = TimeUnit.MILLISECONDS

  Or as in the this example import an implicit value:

  import org.dmonix.prometheus.TimeUnitImplicits.MILLISECONDS
  val requestLatency:Summary = ...
  val result = requestLatency.measure {
    // Your code here.
    }
