Method Details

[hide private]

config(self, name, monitor, thresholds, rrdCreateCommand=None)

source code

Initialize the object. We could do this in __init__, but that would delay creation to after configuration time, which may run asynchronously with collection or heartbeats. By deferring initialization, this object implements the Null Object pattern until the application is ready to start writing real statistics.

rrdFile(self, type, cycleTime, name, minVal='U', maxVal='U')

source code

Create an RRD file if it does not exist. Returns the basename of the rrdFile, suitable for checking thresholds.
