Free Network Monitoring Tools

Our most popular free network monitoring tool is PRTG Network Monitor. This network monitoring software enables you to monitor used bandwidth, as well as the performance and availability of network devices. It supports SNMP, packet sniffing, WMI, NetFlow, sFlow, jFlow and many other protocols.

Free Network Toolset For System Administrators

The free network monitoring tools are completed by a set of several tools that make the administrator's daily life easier. These small helpers make it e.g. easy to find MIBs and convert them to OIDs, to troubleshoot WMI problems, debug NetFlow configurations, test SNMP settings and much more.
