Bandwidth Monitoring
What is the best solution for monitoring network bandwidth at my gateway? I need to be able to see what is eating up my bandwidth, hopefully by port or application. My firewall is a Netscreen 25.
Use any application that uses SNMP (http://en.wikipedia.org/wiki/Simple_Network_Management_Protocol)
e.g.
Switch Center Enterprise 1.5

PRTG traffic grapher!!

free version allows 10 sensors so you can monitor up to 10 interfaces or policies. it is simple to use and works very nicely with netscreen devices.
You can also use nagios with pnp4nagios plugin to do the same thing. In nagios you would create a service to snmp query the bandwidth on an interface or policy, and pnp4nagios will make nice colorful graphs for you
