Interface bit rate graphing

Anyone know how the Interface.OutBitRate and InBitRate are calculated? In the case of out, is it difference in out octets between consecutive polls / poll interval / 8 bits/octet? So if poll interval is 1 min., it would be avg over the minute?

Thanks,
Todd

Search for posts with rate, diff32 and diff64. Rate returns parameter divided by time elapsed since previous call. So if you grab the diff of a counter you can use rate to give the change over time.

rate(diff32(oid(“1.3.6.1.2.1.2.2.1.14.12”)))

Thanks!!
I set up a graph of rate(diff32(oid(“1.3.6.1.2.1.2.2.1.10.1”)))*8 and compared to the standard link graph that gets created when you check ‘Graph bit rate’ on the History tab of the link. Both graphs looked the same.

Cool glad you got it working.
