Network Monitoring Software
Does anyone have any recommendations on a network monitoring software? I want this software to be able to graph bandwidth consumption on the network and be able to pinpoint bottlenecks and who is causing them. I tried Wireshark but that's just a packet sniffer. It's useful, but not what I need. Any suggestions? It doesn't have to be free.
