    • record

      public void record(long amount, TimeUnit unit)
      Description copied from interface: Timer
      Updates the statistics kept by the timer with the specified amount.
      Specified by:
      record in interface Timer
      Parameters:
      amount - Duration of a single event being measured by this timer. If the amount is less than 0 the value will be dropped.
      unit - Time unit for the amount being recorded.

    • record

      public <T> T record(Supplier<T> f)
      Description copied from interface: Timer
      Executes the Supplier f and records the time taken.
      Specified by:
      record in interface Timer
      Type Parameters:
      T - The return type of the Supplier.
      Parameters:
      f - Function to execute and measure the execution time.
      Returns:
      The return value of f.

    • recordCallable

      public <T> T recordCallable(Callable<T> f) throws Exception
      Description copied from interface: Timer
      Executes the callable f and records the time taken.
      Specified by:
      recordCallable in interface Timer
      Type Parameters:
      T - The return type of the Callable.
      Parameters:
      f - Function to execute and measure the execution time.
      Returns:
      The return value of f.
      Throws:
      Exception - Any exception bubbling up from the callable.

    • record

      public void record(Runnable f)
      Description copied from interface: Timer
      Executes the runnable f and records the time taken.
      Specified by:
      record in interface Timer
      Parameters:
      f - Function to execute and measure the execution time.

    • count

      public long count()
      Specified by:
      count in interface Timer
      Returns:
      The number of times that stop has been called on this timer.

    • totalTime

      public double totalTime(TimeUnit unit)
      Specified by:
      totalTime in interface Timer
      Parameters:
      unit - The base unit of time to scale the total to.
      Returns:
      The total time of recorded events.

    • max

      public double max(TimeUnit unit)
      Specified by:
      max in interface Timer
      Parameters:
      unit - The base unit of time to scale the max to.
      Returns:
      The maximum time of a single event.

    • baseTimeUnit

      public TimeUnit baseTimeUnit()
      Specified by:
      baseTimeUnit in interface Timer
      Returns:
      The base time unit of the timer to which all published metrics will be scaled

    • takeSnapshot

      public HistogramSnapshot takeSnapshot()
      Description copied from interface: HistogramSupport
      Summary statistics should be published off of a single snapshot instance so that, for example, there isn't disagreement between the distribution's bucket counts because more events continue to stream in.
      Specified by:
      takeSnapshot in interface HistogramSupport
      Returns:
      A snapshot of all distribution statistics at a point in time.
