Bandwidth utilization (snmp / cisco router)

[Rainer]

Hello,

I'm trying to retrieve the average bandwidth utilization (percent) on a 
cisco router using snmp.
What would be the best way to do this? I've been unable to find a cisco mib 
related to bandwidth percentage (only bits/sec)
According to Cisco, the only way to do is this: 
http://www.cisco.com/warp/public/477/SNMP/calculate_bandwidth_snmp.html (a 
formula using
ifInOctets and ifSpeed)
I know this could be done with cricket / rrdtool, but has anyone succeded 
in doing this using check_snmp or some perl script with net::snmp? (ex. 
check_traffic_percent with parameters for hostaddress, interface number, 
community string, and warning/critical percent levels)

Thanks in advance.
