How to capture/determine utilization on a switched ethernet network?
I have a local area network that I'd like to check network utilization on - our performance seems slow. I have a single router and a few Ethernet switches to connect my 50+ Windows PCs. TCP/IP is main protocol.
I presume I can use Network Monitor or Wireshark for this. Correct? What is the best way to insert my capture PC into the network to determine utilization?
