[mrtg] MRTG compare with previous value

[Kushner Anatoliy]

there are Thresh* params for Targets in mrtg config file, but  they work only when value are bigger on lower then ThreshMinI or ThreshMaxI params. Is it possible to monitor the difference between previous and new value ?

For example if difference between last two values more then 200mbit/s. you can see in attach sample graph with this trouble.
