PRTG makes server performance monitoring easy

Custom alerts and data visualizations make it easy to monitor, identify, and prevent bandwidth, memory, and other server performance issues.



Monitor server performance –
because servers are like clocks

Lots of different pieces need to work reliably, consistently, and  in harmony for your servers to perform at their best.

One single bottleneck – not enough RAM, or a disk read-and-write error, for instance – could affect your whole network.

Paessler PRTG is designed to give you a complete view of all the metrics that could affect your servers' performance. Perfect for local and distributed networks, it keeps a constant eye on your hardware and software, so you can easily maintain (and improve) server availability, speed, and stability.


5 reasons why PRTG is the server performance monitoring tool of your choice

Real-time alerts

Don't get caught out. From CPU overload to issues with RAM, hard disks, or read-and-write speeds, PRTG notifies you at once if there is a problem and thus helps you proactively prevent issues (and the dreaded blue screen).

Historical data

Go back as far as you need to pinpoint when servers started underperforming. You can also generate custom reports including detailed information, even graphs, to update your higher-ups and let them know it's time to upgrade.


Effortless setup

Pick a range of IP addresses in your subnet and PRTG will take it from there. Our automatic network discovery will scan your network, detect available servers, and create suitable monitoring sensors for keeping a close eye on server health and performance.

Wide compatibility

No vendor lock-in guaranteed – PRTG works with all manufacturers whose physical servers support SNMP, SSH, or other common technologies. The same goes for major cloud-based server providers like AWS, Microsoft Azure, or Oracle.

Grow as you go

Whether you're running one server with 4GB of RAM, or multiple 60GB RAM servers, it doesn't matter. Start monitoring for free and upgrade your PRTG license as you expand. Run a distributed network? Set up remote probes to monitor remote servers in multiple locations from one place.


What server performance monitoring looks like in PRTG

Diagnose network issues by continuously monitoring RAM, CPUs, physical and logical drives, and other server components. Show bandwidth, memory, and other performance metrics in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot and fix bottlenecks and maximize server performance.

Effective, all-in-one server performance optimization

Prevent CPU performance issues

Running too many applications simultaneously? Our SNMP CPU Load and Windows CPU Load sensors warn you when your CPUs are close to capacity, so you can address the issue before they're maxed out and your colleagues are unable to continue working.

Optimize RAM performance

Less memory = lower performance.  But you knew that already. Our Windows Pagefile and SNMP Linux Meminfo sensors monitor Windows pagefile and Linux "swap space" activity, so you can free up RAM as soon as you detect server strain and performance bottlenecks.

Track and free up storage space

Our Windows Physical Disk I/O, WMI Free Disk Space (Multi Disk), SNMP Linux Physical Disk and SSH Disk Free sensors help ensure you don't run out of disk space. We also have preconfigured sensors for NetApp, HPE, IBM, Buffalo, Dell, and Lenovo EMC storage systems.

Monitor virtual server performance

The VMware Virtual Machine (SOAP) sensor tracks a VMware virtual machine’s most important performance indicators, including CPU usage, memory, and network connection loads. Use another virtualization provider? We've got that covered too, including Microsoft Hyper-V and Citrix XenServer.

Fix SQL server performance

No more database downtime or sluggish query times. PRTG can monitor most major SQL servers out of the box, including MySQL, Microsoft SQL, Oracle SQL, and PostgreSQL. Or – if you need extended database monitoring for IBM, SAP, and other databases, check out our brand-new product extension PRTG Database Observer.

Monitor server performance: FAQ


1. What is server performance?

Server performance refers to how well a computer server does its job. It's like a waiter in a restaurant – good performance means it quickly and accurately serves your requests. Factors like speed, efficiency, and handling lots of tasks at once contribute to server performance. When a server performs well, websites load fast, and online activities run smoothly. Monitoring and improving server performance help ensure a better experience for users.

2. What is PRTG server performance monitoring?

PRTG is a proprietary software tool that takes the effort out of ensuring your servers always perform at their best. With more than 250 preconfigured sensors, our server performance monitoring tool gives you a complete and comprehensive overview of every component that might impact your servers at a glance, so you can answer this question (and address the problem) double quick.

Available for Windows-based on-premises servers or as a cloud-hosted solution, it's capable of monitoring unlimited 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.

3. Can I use PRTG to test server performance?

Not exactly. PRTG is a monitoring tool and no server performance test software. This means it's primarily designed to track performance metrics and alert you when they dip below pre-established thresholds, not to run tests.

That said, you can simulate performance tests in the following way:

  • Write a script and integrate it into PRTG with a user-defined sensor
  • Run the script at short intervals
  • Measure the corresponding hardware parameters on your server

4. How do I monitor server performance on a distributed network?

Monitoring distributed servers with PRTG is as easy as it gets. Set up remote probes close to the endpoints of the servers you want to monitor, and PRTG will gather the performance data for you in one place. No more trips to remote server farms (unless you fancy one).

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

PRTG: The multi-tool for sysadmins

Adapt PRTG individually and dynamically to your needs and rely on a strong API:

  • HTTP API: Access monitoring data and manipulate monitoring objects via HTTP requests
  • Custom sensors: Create your own PRTG sensors for customized monitoring
  • Custom notifications: Create your own notifications and send action triggers to external systems
  • REST Custom sensor: Monitor almost everything that provides data in XML or JSON format
