ClassDescriptionDeprecated.This class is deprecated.Class used to interpolate datasource values from the collection of (timestamp, values) points using natural cubic spline interpolation.Class which should be used for all calculations based on the data fetched from RRD files.Interface to be used for custom datasources.Class used to interpolate datasource values from the collection of (timestamp, values) points.A enumeration of interpolation methodsDeprecated.use implementations of
IPlottableinsteadAn abstract class to help extract single value from a set of value (VDEF in rrdtool) It can be used to add new fancy statistical calculation with rrd valuesCalculate the average of the data points.The sort used by rrdtool for percent, where NaN < -INF < finite values < INFFind the first valid data point and it's timestampFind the first last valid point and it's timestampCalculate the correlation coefficient of the least squares line.Calculate the y-intercept of the least squares line.Calculate the slop of the least squares line.The biggest of the data points and it's time stamp (the first one) is stored.The smallest of the data points and it's time stamp (the first one) is stored.Store all the informations about a datasource point, for predictive and consistent sortingFind the point at the n-th percentile.Calculate the standard deviation for the data point.Calculate the sum of the data points.This class store both the value and the time stamp It will be used by graph rendering legend
