Method Detail

• calculate

  public void calculate​(long tStart,
                        long tEnd)
                 throws RrdException

  Realize the calculation of this definition, over the given time period

  Parameters:

  tStart - the time period start

  tEnd - the time period end

  Throws:

  RrdException - Thrown if we cannot get a percentile value for the time period.

• setTimestamps

  void setTimestamps​(long[] timestamps)

  Overrides:

  setTimestamps in class Source

• getAggregates

  Aggregates getAggregates​(long tStart,
                           long tEnd)
                    throws RrdException

  Same as SDef; the aggregates of a static value are all just the same static value. Assumes this def has been realized by calling calculate(), otherwise the aggregated values will be NaN

  Overrides:

  getAggregates in class Source

  Throws:

  RrdException

• getPercentile

  double getPercentile​(long tStart,
                       long tEnd,
                       double percentile)
                throws RrdException

  Returns just the calculated percentile; the "Xth" percentile of a static value is the static value itself. Assumes this def has been realized by calling calculate(), otherwise the aggregated values will be NaN

  Overrides:

  getPercentile in class Source

  Throws:

  RrdException
