A great and very popular freeware tool for monitoring traffic
utilization and creating on the fly graphs is MRTG located at:
http://ee-staff.ethz.ch/~oetiker/webtools/mrtg/mrtg.html
you normally run MRTG every 5 minutes to check the MIB objects that
contain bit counters to calculate bandwidth. i'm sure you could write a
little module to trigger an alarm when the bandwidth reaches
thresholds. There may even be a sample of one in the contrib directory
already.
does anyone know offhand if IOS can generate SNMP traps when load
reaches a certain amount?? that would definitely be more effective and
quicker.
hope this helps!
