Custom alerts and data visualization let you quickly identify and prevent network outages and downtime.
If you’re looking for free network monitoring tools but don’t want to limit yourself with regards to the feature set, Paessler PRTG Network Monitor has you covered.
Its free edition comes with 100 sensors free for life. Apart from NetFlow sensors, which are only available in the commercial editions, the free version offers the full functionality (server monitoring, application monitoring, performance test tools, VMware monitoring, VoIP monitoring, and much more).
Need more than 100 sensors to monitor a larger IT infrastructure? No problem. PRTG is easily scalable – see our commercial licenses and pricing here.
And if you’re still unsure, we throw in a fully-featured, 30-day trial with an unlimited number of sensors so that you can try out everything. No strings attached.
Our all-in-one network monitoring software helps you monitor, maintain and provision your computer networks. It offers comprehensive performance and fault management for networks and servers and monitors networks for technical problems caused by overloaded servers, crashed connections, or users.
With PRTG, you can easily break down the bandwidth utilization of your devices by different parameters, such as IP address, port number, or protocol. Immediately identify bandwidth bottlenecks and the applications, servers, and users that are using up your bandwidth.
Continuously check whether your servers, websites, and other endpoints are available and reachable using Ping. By knowing your systems' uptimes and downtimes, you can immediately detect faults or system slowdowns, which also helps MSPs meet their Service Level Agreements (SLAs).
Monitor network speed, CPU load, memory usage, website loading times, response time, round-trip times (RTT), and many other parameters that influence the performance of your infrastructure and, ultimately, business processes. Use PRTG to make sure that your network stays stable and reliable.
Diagnose network issues by continuously tracking the status and performance of your network using SNMP, WMI, SSH, packet sniffing, flow protocols, and other technologies. Show uptime, disk health, CPU usage, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot your on-premises, cloud, and virtual infrastructure.

With the freeware edition of PRTG, you can get started with network monitoring in a matter of minutes. Our auto-discovery function detects all the devices within a given IP address range and automatically incorporates them into your monitoring environment.
PRTG’s flexible licensing makes it easy to scale up or down as needed. You pay only for the number of sensors you need. After your 30-day free trial of the unlimited version of PRTG, you can still use the free version with 100 free sensors.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
