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. <br />
<br />
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?<br />
<br />
Thank you.

How to capture/determine utilization on a switched ethernet network?

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).
