PRTG Network Monitor is Paessler's powerful bandwidth and network monitoring tool. It uses SNMP, packet sniffing, and NetFlow / sFlow to capture network traffic and measure network throughput. The PRTG tcp port monitor is easy to set up and very intuitive to use. For easy port monitoring, it includes the SNMP traffic sensor, which Supports monitoring bandwidth (bits/s) and volume (bytes), as well as the number of packets and errors via SNMP for a port of a network card on a PC, server, switch, firewall, printer etc. In switched networks, you can use packet sniffing for advanced port monitoring: using the monitoring port, you can easily monitor internet usage across your network.

Apart from port monitoring, PRTG's comprehensive functionality includes computer monitoring (CPU and memory load, free disk space, etc.), server monitoring (file, email, database servers etc.), VoIP traffic monitoring (packet loss, jitter, latency), URL monitoring (website uptime and functionality), and much more.

PRTG Network Monitoring Software is available in two editions. For basic, free port monitoring, the Freeware Edition may be downloaded and used for personal and commercial use completely free of charge. For more advanced needs, licenses for the Commercial Editions start at $440 / €330.
