  2. def create(name: String, value: Try[Number], decayFactor: Option[Double]): Option[Metric]

    Creates a new Metric instance if the Try is successful and the value is valid, otherwise None is returned.

    Creates a new Metric instance if the Try is successful and the value is valid, otherwise None is returned. Invalid numeric values are negative and NaN/Infinite.

  3. def create(name: String, value: Number, decayFactor: Option[Double]): Option[Metric]

    Creates a new Metric instance if the value is valid, otherwise None is returned.

    Creates a new Metric instance if the value is valid, otherwise None is returned. Invalid numeric values are negative and NaN/Infinite.

    An defined value is neither negative nor NaN/Infinite:

    An defined value is neither negative nor NaN/Infinite:

    • JMX system load average and max heap can be 'undefined' for certain OS, in which case a -1 is returned
    • SIGAR combined CPU can occasionally return a NaN or Infinite (known bug)
