Aggregator | |
CDef | |
CubicSplineInterpolator |
Class used to interpolate datasource values from the collection of (timestamp, values)
points using natural cubic spline interpolation.
|
DataProcessor |
Class which should be used for all calculations based on the data fetched from RRD files.
|

LinearInterpolator |
Class used to interpolate datasource values from the collection of (timestamp, values)
points.
|
Normalizer | |
PDef | |
Plottable |
Abstract class to be used for custom datasources.
|
RpnCalculator | |
Source | |
Variable |
An 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 values
|
Variable.AVERAGE |
Calculate the average of the data points.
|
Variable.ComparPercentElemen |
The sort used by rrdtool for percent, where NaN < -INF < finite values < INF
|
Variable.FIRST |
Find the first valid data point and it's timestamp
|
Variable.LAST |
Find the first last valid point and it's timestamp
|
Variable.LSLCORREL |
Calculate the correlation coefficient of the least squares line.
|
Variable.LSLINT |
Calculate the y-intercept of the least squares line.
|
Variable.LSLSLOPE |
Calculate the slop of the least squares line.
|
Variable.MAX |
The biggest of the data points and it's time stamp (the first one) is stored.
|
Variable.MIN |
The smallest of the data points and it's time stamp (the first one) is stored.
|
Variable.PercentElem |
Store all the informations about a datasource point, for predictive and consistent sorting
|
Variable.PERCENTILE |
Find the point at the n-th percentile.
|
Variable.PERCENTILENAN | |
Variable.STDDEV |
Calculate the standard deviation for the data point.
|
Variable.TOTAL |
Calculate the sum of the data points.
|
Variable.Value |
This class store both the value and the time stamp
It will be used by graph rendering legend
