identify bandwidth hog
Posted on 2009-05-14
I am looking for a way to identify which computer(s) is saturating our T1. Yesterday, on more than one occasion, we experienced complete saturation resulting in short periods of downtime.
The network is comprised of:
Cisco 1841 Router
Cisco Catalyst 2960
2 Wireless Access Points
and various (roughly 60) wireless and wired computers/servers (running XP, 2003, and Mac OS X)
I'm looking for a way to monitor and discover which computer is using all of the bandwidth (preferably open source, but commercial is not a problem). Any advice regarding tools/nex steps would be greatly appreciated.
