I don't see any mention of such functionality, but I'm not sure where to look other than a glance at the manpage. My SPECIFIC problem is that we want to share our burstable-to-T1 (through UUnet. This is the thing that BBN has been doing for a long time) connection with another company just down the hallway in our office building. To understand who should be paying what, we'd like to be able to track what the bandwidth usage is in a way analogous to however it is that they do it. For reference, they average the bandwidth over 5 minute intervals (the samples). Then the highest sample in the bottom 95% of the samples is your "bandwidth utilization" that they charge you at. Clearly, this could be produced with a log message every N minutes explaining what the utilization had been over the previous N minutes and resetting. If there are facilities to do this that I'm overlooking, please do tell. I would be very glad to know.
