Data Specification: (Data1) Five minute exponentially decaying sum of moving average of input and output bits per second (Data2) Percent of input and output packets in error or discarded at the router during each five-minute polling interval, multiplied by 1000.

(Strength2): Hot links to underlying MRTG graphs offer glimpses of more specific trends and historical averages.
