    • longTaskTimer

      public LongTaskTimer longTaskTimer(String name, String... tags)
      Measures the time taken for long tasks.
      Parameters:
      name - Name of the gauge being registered.
      tags - MUST be an even number of arguments representing key/value pairs of tags.
      Returns:
      A new or existing long task timer.

    • longTaskTimer

      public LongTaskTimer longTaskTimer(String name, Iterable<Tag> tags)
      Measures the time taken for long tasks.
      Parameters:
      name - Name of the gauge being registered.
      tags - Sequence of dimensions for breaking down the name.
      Returns:
      A new or existing long task timer.

    • counter

      public <T> FunctionCounter counter(String name, Iterable<Tag> tags, T obj, ToDoubleFunction<T> countFunction)
      Tracks a monotonically increasing value, automatically incrementing the counter whenever the value is observed.
      Type Parameters:
      T - The type of the state object from which the counter value is extracted.
      Parameters:
      name - Name of the gauge being registered.
      tags - Sequence of dimensions for breaking down the name.
      obj - State object used to compute a value.
      countFunction - Function that produces a monotonically increasing counter value from the state object.
      Returns:
      A new or existing function counter.

    • counter

      public <T extends Number> FunctionCounter counter(String name, Iterable<Tag> tags, T number)
      Tracks a number, maintaining a weak reference on it.
      Type Parameters:
      T - The type of the state object from which the counter value is extracted.
      Parameters:
      name - Name of the gauge being registered.
      tags - Sequence of dimensions for breaking down the name.
      number - A monotonically increasing number to track.
      Returns:
      A new or existing function counter.

    • timeGauge

      public <T> TimeGauge timeGauge(String name, Iterable<Tag> tags, T obj, TimeUnit timeFunctionUnit, ToDoubleFunction<T> timeFunction)
      A gauge that tracks a time value, to be scaled to the monitoring system's base time unit.
      Type Parameters:
      T - The type of the state object from which the gauge value is extracted.
      Parameters:
      name - Name of the gauge being registered.
      tags - Sequence of dimensions for breaking down the name.
      obj - State object used to compute a value.
      timeFunctionUnit - The base unit of time produced by the total time function.
      timeFunction - Function that produces a time value from the state object. This value may increase and decrease over time.
      Returns:
      A new or existing time gauge.

    • timer

      public <T> FunctionTimer timer(String name, Iterable<Tag> tags, T obj, ToLongFunction<T> countFunction, ToDoubleFunction<T> totalTimeFunction, TimeUnit totalTimeFunctionUnit)
      A timer that tracks monotonically increasing functions for count and totalTime.
      Type Parameters:
      T - The type of the state object from which the function values are extracted.
      Parameters:
      name - Name of the gauge being registered.
      tags - Sequence of dimensions for breaking down the name.
      obj - State object used to compute a value.
      countFunction - Function that produces a monotonically increasing counter value from the state object.
      totalTimeFunction - Function that produces a monotonically increasing total time value from the state object.
      totalTimeFunctionUnit - The base unit of time produced by the total time function.
      Returns:
      A new or existing function timer.
