The rrdMultiFile Javascript module implements a set of classes that can be used to combine several RRDFile objects into one. They all implement the same interface as RRDFile. |
The main class in this module is RRDFileSum. Given a list of similar RRDFile objects, it creates a new object that behaves like a RRDFile object where the input shave been summed up.
This is the main class of the package. It is also the only class the user ever needs to explicitly instantiate.
The RRDFileSum constructor has two argument:
A list of similar RRDFile
objects.
They must all have the same DSes and the same RRAs.
A boolean (default=true) – This value defines how to treat undefined values. If true, they are counted as zeros and the sum will always succeed. If it is false, any undefined value in one of the input objects will result in the sum being marked as undefined.
This class implements the same interface as RRDFile.
This class implements the same interface as RRDRRA.
