PRTG makes it easy to monitor your CPU usage.

Custom alerts and data visualization make it easy to monitor, identify, and prevent system performance and stability issues.











Fine-tune your system for peak CPU performance & system reliability

CPU load monitoring is a critical aspect of IT management, but not just any monitoring will do. You need a CPU usage monitoring tool that supports you 24/7/365. Paessler PRTG provides round-the-clock, real-time monitoring on multiple devices, at the office, and on the go. Your systems perform better, and you get peace of mind.

Optimize your server performance

Balance the workload of your servers better with uniform load distribution. For servers, computers, and other processor-controlled hardware to be stable, CPU computing power has to be evenly distributed.

PRTG helps you monitor your overall processor load, as well as the loads of individual CPU cores.

Monitor your CPU
in real time

Set up warning and error thresholds to notify you in the case of abnormal CPU usage patterns.

Real-time, always-on CPU load monitoring makes sure that you’ll be alerted before the situation reaches critical, allowing you to quickly identify performance bottlenecks, prevent system overloads, and maintain an efficient IT infrastructure.

Accurately plan for capacity upgrades

Analyze historical CPU usage data so you can understand trends and make informed decisions about capacity upgrades.

While reviewing this data can be complex, PRTG simplifies this process with a central dashboard and easy-to-understand visual graphs for 2-day, 30-day, and 365-day historical data analysis.

Prevent downtime for business continuity

Reduce the risk of downtime during peak usage periods with the visibility and control you need over your IT systems.

PRTG CPU load monitoring helps you identify malfunctioning or slow processes and critical CPU usage, optimize load balancing, speed, and performance, and get notified before a CPU reaches overload.


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

5 reasons to choose PRTG as your CPU load monitor

Customize your alerts

Set your alerts to be as sensitive as you need them to be. With PRTG, you can define custom notification triggers based on specific CPU load thresholds so you can make upgrades and fix capacity concerns before they’re an actual issue.

Get immediate notifications

PRTG CPU load monitoring will show you exactly where the load is distributed and how much is placed on your servers. If the values get too high, PRTG will automatically send you an alarm via SMS, email, push notification, and more when the defined percentage is reached.

Maintain an overview

Display your CPU load info on a single, customizable dashboard. PRTG lets you prepare your long-term CPU load data in accordance with your own individual needs, and automated reports in HTML, PDF, CSV, or XML format keep your coworkers and higher-ups in the know.

Monitor from anywhere

Our PRTG apps for iOS or Android make CPU load monitoring travel-friendly. Remotely monitor your entire IT infrastructure, computers, server hardware, and network security on your phone, desktop, or laptop. If you have internet access, you have access to your CPU data.

Monitor CPU Usage: FAQ


1. What systems is PRTG compatible with?

PRTG CPU load monitoring is compatible with both Windows and Linux/Unix-based systems. PRTG uses SNMP to read the CPU loads of devices made by various manufacturers. You can also use WMI for Windows systems and revert to SSH for Linux-based devices or MacOS.

2. What data does PRTG collect?

PRTG is an all-in-one monitoring tool. It collects data on CPU load, including current computing power as a percentage, in total, and per processor. It monitors the CPU temperature and other health data for various devices, as well as other important system parameters, such as RAM, memory, network cards, hard disk space, bandwidth, and more.

3. How does PRTG CPU load monitoring work?

CPU load monitoring measures computing power as a percentage, which rises with increased process demands. The more processor cores your CPU has, the less strain on each core. As a result, the CPU load will be lower. PRTG monitors the overall processor load and the loads of individual CPU cores.

4. Can CPU load monitoring detect hardware issues?

CPU load monitoring primarily detects performance issues, although consistent high usage can sometimes indicate hardware problems. However, PRTG is a comprehensive monitoring solution that includes hardware monitoring, disk space monitoring, and more.

5. 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.


PRTG the multi-tool
