I use an Adtran Atlas 550 and these numbers are available via snmp on this
box (with the help of Marc, I don't know his last name).  You might try
looking through your docs or just doing an snmpwalk.

I found our TX and RX Utilization by viewing these number via a telnet
session and then viewing various snmp values with GetIf.  This comparison
led me to the correct OID.  Adtran includes the Average TX and RX
Utilization and a Max TX and RX utilization for the current day.  Previous
days are available via different OID's.

Hope this helps.

Subject: RD: [mrtg] Percentage Utilisation ?



Hi,

I've recently looked at deployment of MRTG for coverage of our WAN links'
throughput. I'm quite impressed so far but my management say that they would
be happier with seeing a pair of graph lines in the chart that just show
percentage utilisation.

I replied that they should look at the figures below the graph, but they
want the graph to be in the form of a percentage of available bandwidth
rather than the actual number of octets.

I have tried many different combinations of the target expressions and tried
to get a situation where I can divide each throughput figure by the value of
(100/MaxBytes) to get a percentage.

I have tried playing with the dorelpercent option, but that just seems to
work with one value relative to the other.

Has anyone achieved this? I'd be very keen to know (and very grateful).
