Track network usage with Daniele Giabbai's Net Meter. The program also features a system tray icon and Visual Basic 6 source code.
This application monitors network traffic and extracts IP addresses and MAC hardware addresses. If any new combination is detected it is logged to a database and in addition an e-mail can be sent via SMTP to the network manager or security staff. You can print reports directly to PDF or Excel. IPNetMon can be used to determine the active IP devices in your network as a starting point of a security review.

Using debug mode will show source and destination in real-time as well as identify SNMP community strings on the network.
