Cisco Temp Tracking

Do you need a whole datasource to do this? What timeframe are you looking at for your threshold window? The alert trigger interval does just what you're looking for, if I understand your problem. It can be set to a maximum of 60 poll cycles. If you're polling at 5 minute intervals, that at least gives you a 5 hour window. Since you're not as interested in immediate alerts, you could up the poll interval which would up that threshold window. 

Alternatively, you could construct a Groovy based complex datapoint to call the LM API to get the data from the last X polls or X minutes/hours/days ago and store that value. Then you could add a complex datapoint to calculate the average temperature increase as the slope of the line intersecting those two points.

The last is needed as a primitive in LM.  Going to "the API" is a PITA without library support.
