Known Subclasses:: MinMaxThreshold.MinMaxThresholdInstance

A ThresholdInstance is a threshold to be evaluated in a collector within a given context.

Instance Methods

[hide private]

name(self)
return the name of this threshold (from the ThresholdClass)

source code

context(self)
Return the ThresholdContext for this ThresholdInstance

source code

key(self)
Unique data that refers to this object within a collector

source code

dataPoints(self)
Returns the names of the datapoints used to compute the threshold

source code

check(self, dataPoints)
The given datapoints have been updated, so re-evaluate.

source code

checkRaw(self, dataPoint, timeOf, value)
A new datapoint has been collected, use the given _raw_ value to re-evalue the threshold.

source code

getGraphElements(self, template, gopts, namespace, color)

check(self, dataPoints)

source code

The given datapoints have been updated, so re-evaluate. returns events or an empty sequence
