Packet Monitoring

[Ethan Galstad]

One suggestion might be to setup an event handler for the service in 
Nagios that's generating alerts.  Have the event handler run a script 
 if bandwidth usage goes into a warning or critical state.  The 
script should kick off a seperate process (i.e. tcpdump) that sniffs 
network traffic for the next 10 minutes or so.  That way you can just 
take a quick look at 10 minutes worth or data rather than an entire 
night's worth.
