PRTG Network Monitor - IP Sniffer and More

PRTG Network Monitor is Paessler's powerful network monitoring solution. It ensures the availability of network components, analyzes network traffic and usage. It saves costs by avoiding outages, optimizing connections, saving time, and controlling service level agreements.

Analyze Network Traffic Using PRTG's IP Sniffer, SNMP and NetFlow

The software includes a packet sniffer / IP sniffer, which allows you to analyze network traffic by IP address or protocol. Thanks to PRTG's top list feature you can see which computer or application uses most LAN bandwidth.

Apart from the IP sniffer functionality, PRTG also supports SNMP, WMI, and NetFlow. The SNMP software can also be used to monitor network bandwidth. Although WMI and SNMP monitoring will not give you the same level of detail as the IP sniffer, it puts much less load on the server and should therefore be used if you just need a basic bandwidth viewer to tell you your overall bandwidth usage.

NetFlow is an advanced method of network usage data acquisition which is supported by many Cisco routers and switches.

Load and Uptime Monitoring

However, PRTG is not only an IP sniffer, but also includes comprehensive performance and uptime monitoring functionality. Using WMI and SNMP, PRTG monitors parameters such as CPU and memory load, free disk space, availability, temperature, etc. The network load monitor runs on all Windows versions from XP onwards, and comes in very handy for troubleshooting Windows XP services.
