Your organization is connected to the Internet, but can you ensure that it is used appropriately and effectively? Do you want to monitor and count the IP traffic between your local area network (LAN) and Internet?

TrafMeter is a Windows-based tool providing realtime traffic accounting and monitoring. You can use it to count useful traffic of your computer or use to build the traffic accounting system for all PCs in your office LAN.

Limitations:

Unlimited number of filters for captured traffic, defining network packets which are used for tracking/reporting.

Creation of rulesets for various monitoring purposes. The rulesets can be used for single hosts, subnets, as well as specific groups of hosts - i.e. all hosts in/not in your LAN, specific IP protocols (ICMP,TCP,UDP,OSPF,etc).

Real-time presentation of traffic activity via graphical charts. Each filter is represented by a unique color, which allows the webmaster and/or administrator to easily 'see' the Internet connection usage of individual users.

Traffic Report generation via XML.

Recording Traffic Counters into the many common databases such as Microsoft SQL Server, Microsoft Access, MySQL and etc (not available in Lite version).

Tracking network packets for the different filters, letting you analyze and comment on the monitored traffic which may include MAC addresses from Ethernet headers and the ToS field from IP headers (not available in Lite version).
