PRTG can use Netflow if supported by your switch(es) to get packed info. Without, it only collects interface statistics without details about IP addresses.<br />
<br />
WireShark and similar tools only work if run on the source or destination of traffic. Other than that you only see broadcast or multicast packets.

Are these managed switches? If so, most provide a send and receive rate. Some even show a 5 min average.<br />
<br />
Wireshark is great for sniffing. The only problem is that you will only be able to see broadcast traffic on a switch unless you have the ability to span a session.<br />
<br />
If you suspect a particular machine you could just go to that machine and look at the network from there.

If you have NetFlow enabled devices, that's the best way to get information. <a href="http://www.adremsoft.com/netcrunch" rel="ugc">NetCrunch 8</a> has NetFlow built-in to it's all-in-one suite of monitoring.

Monitoring 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).

Network Analysis

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

Network Management

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
