Q. What is a sensor?
A sensor in PRTG speech is defined as one aspect that you can monitor on a device, such as the CPU load on a machine, a port of a switch, a specific URL or the traffic of a network connection. See this list for more sensor types.
A. The licensing options are based on the number of sensors and not the number of devices. This flexibility allows you to add sensors where you need them. Most of our customers use roughly 10 sensors per device which means that you can easily monitor 100 devices with the PRTG 1000 license. If you hit a sensor limit you can simply upgrade to a higher license by just paying the price difference.
For the unrestricted sensor licenses the number of sensors is not limited by the PRTG licensing but by technical constraints like performance limitations of hardware, network and other software. If you are planning a large installation please refer to our sizing recommendations.
PRTG is a comprehensive network monitoring application for Windows-based systems. It is suitable for networks of all sizes and capable of LAN, WAN, WLAN, and VPN monitoring. You can also monitor physical or virtual web, mail, and file servers, Linux systems, Windows clients, routers, and much more.
PRTG monitors network availability and bandwidth usage, as well as various other network parameters such as quality of service, memory load, and CPU usage, even on remote machines. PRTG provides system administrators with live readings and periodical usage trends to optimize the efficiency, layout, and setup of leased lines, routers, firewalls, servers, and other network components.
The software monitors a network that uses Simple Network Management Protocol (SNMP), Windows Management Instrumentation (WMI), packet sniffer, Cisco NetFlow, IPFIX, sFlow, jFlow, and many other industry standard protocols. It runs on a Windows-based machine in your network for 24 hours a day. PRTG constantly records the network usage parameters and the availability of network systems. The recorded data is stored in an internal database for later analysis. 
System Requirements on Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows 11, or Windows 10.
