PRTG makes network performance monitoring easy

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



Wanted: 100% uptime


It's every sysadmin's dream. Well, that, and winning the lottery so you can retire to the Bahamas.

But even if you were to achieve it, 100% uptime would do your network little good if it still struggled with low bandwidth, overloaded servers, or virtual machines that performed like it's a Sunday afternoon in August.

Paessler PRTG tracks the availability, health, and performance of every component in your network, 24/7. That means you'll find out about any issues (and be able to fix them) before your colleagues can notice, and plan ahead so your infrastructure is always well-placed to support your organization's growth.



PRTG is compatible with all major vendors, products, and systems

Monitor network performance: FAQ


What is network performance?

Network performance refers to the efficiency and effectiveness of data transfer and communication within a computer network. It is measured by factors such as bandwidth, latency, and reliability. Higher network performance indicates faster data transmission, lower delays, and a more stable connection.

What is network performance monitoring?

Network performance monitoring involves the continuous observation and analysis of a computer network's key metrics to ensure optimal functionality. This process includes tracking factors such as bandwidth utilization, latency, packet loss, and device performance. By using specialized network performance monitor tools and software, administrators can identify issues, troubleshoot problems, optimize the network for efficient data transfer, and prevent downtime.

What is PRTG network performance monitoring software?

PRTG is a proprietary software tool that tracks the health and performance of every component that forms part of your network. Available for Windows-based on-premises servers or as a cloud-hosted solution, it's capable of monitoring unlimited local, remote, and virtual network devices, bringing critical system data together in one simple, intuitive interface you can access from anywhere: at the office, at home, or on the go.

Why use Paessler PRTG network performance monitoring tools?

Because it's comprehensive, infinitely customizable, and suitable for long-term monitoring — perfect for getting to the bottom of intermittent issues. "Of course you'd sing your own praises," we hear you say. Well, the proof of the pudding is in the eating. Try PRTG for free, no strings, and see for yourself. 80% of our paying customers say PRTG pays for itself within weeks.

Can PRTG also test network performance?

Yes. Use the Ping v2 sensor to check the availability of all devices in your network and test network performance. And if a device is connected to the network via ethernet, that's no problem. Use PRTG's ethernet monitoring capabilities to test your wired connections and the overall performance of your LAN.

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.
