Agent is a lightweight, simple and free Realtime Network Traffic Monitoring Tool for your PC that doubles as a simple Protocol Analyzer and Packet Sniffer. Easily capture traffic to the PDU Capture window and then export to Raw Binary, XML or CSV (easily imported into Microsoft EXCEL). Agent can also import the binary format it saves in.
Sniffer Agent offers a realtime look at conversations, protocols, and even allows a NetStat to be run. NetStat shows which programs are listening, receiving, or sending information on certain TCP ports and the IP address of the remote computer involved.
Unlike most protocol analyzers and sniffers there is no need to install a dedicated capture driver on your computer so installation is simple and you are up and running within seconds.
