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, context, gopts, namespace, color, legend, relatedGps) Produce a visual indication on the graph of where the threshold applies. | source code

### check(self, dataPoints) | source code
The given datapoints have been updated, so re-evaluate. returns events or an empty sequence

### checkRaw(self, dataPoint, timeOf, value) | source code
A new datapoint has been collected, use the given _raw_ value to re-evalue the threshold. returns a sequence of events.
