PRTG makes tracking network usage easy

Custom alerts and data visualizations make it easy to monitor, identify, and prevent low bandwidth, packet loss, latency, and other network performance issues.



Not too low, not too high: the quest for optimal network utilization

Network usage has a sweet spot.

Too low, and it might be a sign there's an outage, resource allocation issue, or even a security breach. Too high, and it risks causing packet loss, latency, or overloading the system.

Paessler PRTG's more than 250 preconfigured sensors track all network activity and monitor usage across your whole network. Once you pick your parameters, it works quietly (and tirelessly) in the background, alerting you if usage goes above or below the recommended threshold so you can dial it back to "just right".








Keep your network fighting fit: Why choose PRTG as your network usage monitoring tool

Round-the-clock monitoring

Set it and forget it. PRTG monitors your network 24 hours a day, 7 days a week, and alerts you the second something's not working as it should.

That means you can go home relaxed, enjoy the weekend, and unplug completely while on vacation. PRTG gives you real peace of mind, safe in the knowledge your network is in good hands.

Effortless troubleshooting

Zoom in on what's causing a performance issue…before it becomes an actual problem. PRTG's comprehensive, easy-to-use dashboards put key stats at your fingertips in real time.

You’ll be like an eagle who sees a mouse from hundreds of feet away – and already on the floor tightening the screws on the server before your coworkers have a chance to put down their coffee and call the support line.

Proactive planning

All good things come to an end. Even trusted network components. PRTG tracks the health and performance of your routers, switches, and any other devices connected to your network over time, showing you which ones are still going strong, and which ones you should retire.

Your network thus stays fit and trim well into the future – and you can save yourself some wrinkles.








What network usage monitoring looks like in PRTG

Diagnose network issues by continuously monitoring bandwidth, load, and other performance stats. Show server status, data transfer speeds, packet loss, latency, and other usage monitoring metrics in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot bottlenecks, underperformance, and more.


Start monitoring network usage with PRTG and see how it can make your network more reliable and your job easier.

Monitor network usage: FAQ


What is network usage monitoring?

Network usage monitoring is the practice of tracking and analyzing the data traffic flowing through a computer network. It involves observing various parameters such as bandwidth consumption, data transfer rates, and types of network activities. This monitoring helps administrators understand how network resources are being utilized, identify potential bottlenecks or security threats, and optimize network performance.

By collecting and analyzing usage data, organizations can make informed decisions about resource allocation, capacity planning, and security measures to enhance overall network efficiency and reliability.

Why use PRTG as my network utilization monitor?

Because it makes spotting (and fixing) network performance issues as easy as 1, 2, 3. PRTG keeps a close eye on your network's health stats and brings them together in comprehensive, easy-to-understand dashboards, enabling you to clear bottlenecks, load up on bandwidth, and ditch hardware that's past its prime before they slow your colleagues down (and your colleagues start calling to complain).

How can I optimize network usage?

  • Bandwidth management: Implement Quality of Service (QoS) policies to prioritize critical network traffic over less essential data, ensuring that bandwidth is allocated efficiently according to organizational needs.
  • Traffic analysis and monitoring: Continuously monitor network traffic to identify bandwidth-hungry applications or devices. Use this data to optimize network configurations.
  • Content caching: Deploy caching servers or content delivery networks (CDNs) to store frequently accessed content closer to end-users, reducing the need for repetitive downloads across the network and conserving bandwidth.
  • Protocol optimization: Optimize network protocols and configurations to minimize overhead and improve data transfer efficiency. For example, enabling compression or leveraging newer protocols like HTTP/2 for web traffic can reduce latency and bandwidth consumption.
  • Update and upgrade infrastructure: Regularly update network hardware, firmware, and software to take advantage of performance enhancements and security patches.
  • Bandwidth throttling and traffic shaping: Implement bandwidth throttling and traffic shaping mechanisms to control the flow of data across the network, ensuring that critical applications receive adequate resources while preventing non-essential traffic from consuming excessive bandwidth.

Can PRTG only monitor network utilization?

No – PRTG can do way more. As an all-in-one network monitoring tool, PRTG can monitor any network device and variable you can think of, from servers, routers, and firewalls to applications, cloud services, and virtual environments.

What is a sensor in PRTG?

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.
