thresholds on traffic, and notify us if needed?
RMON alarms and events for one. These are available on pretty much all recent versions of IOS. You can set a rising or falling threshhold on any MIB variable you like, and period of time between polls. This will generate a trap to a network management station, and you can choose to do what with you will the alarms.

If you want to tie this stuff into scripts you can use the net-snmp trap daemon to call various trap handlers that could do something keep track of the duration of the spike or send an alert.

Another thing that is out there in later releases is the EVENT MIB. This is probably overkill for what you want, and the only way to configure it is through SNMP.

For all of this stuff there is documentation on CCO.

For RMON alarms and events, see:

For the EVENT MIB see:

The net-snmp package is available at SourceForge:
