is it possible to configure an alert (Notification) if the measured value of a sensor increases by x percent within a configurable window of minutes/hours?
Example: I'm monitoring the router interface to the internet.
I want to be able to configure a notification if the reported bandwidth/throughput on that interface 'sharply' increases (traffic spike) for 50% within a window of 10 minutes. Similar to the threshold notification, just not based on a fixed value (bandwidth), but on an increase by x percent.
BTW: I know the automatic monitoring (and alerting) of the measured values (comparing the current value with the value of the same period last week), but that's not what I want.
