Speed vs. network performance:
What do you want to test?
Home use: Internet speed
If you're looking for a quick and easy way to test the speed of your Internet, then go with an online tool such as fast.com. This tool is operated by none other than Netflix. Many Internet users run speed tests at home to view their megabits per second when their streaming service gets bogged down.
Business use: Network performance
IT administrators, on the other hand, are in a completely different situation. They need to know more about the performance of their network. For example, their servers, routers, and switches – or the website and specific applications. When malfunctions occur in the network, the company immediately suffers and support inquiries go through the roof.
For a smooth-running network: More than 300,000 system administrators worldwide use these PRTG sensors
iWhat is a sensor?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Network performance testing: How PRTG can help – and when other tools are necessary
Network performance testing
PRTG is not your usual network performance testing tool. It won’t let you run a one-time test as you would via the command prompt (e.g. with ping). A one-time test is often of little use. With PRTG, you monitor your bandwidth continuously and receive an alert if a threshold value is exceeded.
Network performance monitoring
Upon installing PRTG, the Auto Discovery feature automatically checks the reachability of all the devices in a given IP range and incorporates these devices into your monitoring environment. You can then create sensors to keep a constant eye on specific values associated with your devices.
Network performance analysis
PRTG provides you with all the key performance data on bandwidth, devices, and applications. For more in-depth analysis of specific data packets, you’ll need a special data analysis tool.

The advantages of PRTG
Centralized tool –
for a quick and easy
With PRTG, you get one central monitoring tool for your entire IT infrastructure. Our software keeps a constant eye on hardware, traffic, and more. Sensors send all monitoring data to an easy-to-read dashboard.
– for prompt
If a malfunction occurs, our tool will notify you at once. All notification threshold values are customizable. You can therefore take action quickly – before the network goes down.
Compatible with all manufacturers –
for greater ease of use
Our network tool is compatible with all the biggest manufacturers, including HP, Dell, Juniper, Cisco, and many more. With PRTG, you no longer need to monitor devices one-by-one but can keep an eye on the performance of your entire network from one central interface.
Examples of network testing with PRTG
Testing load times
PRTG continually monitors the load times of your website. This is especially useful if you do business abroad and your website is accessed by users worldwide. It’s not possible to set up a live load time test with PRTG. For more information, please see our page on website load tests.
PRTG is not a server performance testing tool per se, but it can be used to simulate a performance test. For example: write a script, let it run in short intervals with the help of a user-defined script sensor, then measure the corresponding hardware parameters.

Testing for maximum bandwidth would cause your network to freeze up. No administrator wants that. Instead, test your bandwidth by generating small and short spikes in the load. For example: download a file every few minutes and simultaneously measure your bandwidth.

Quickly see if PRTG is working –
even while on the go
PRTG can be started within minutes and it's compatible with many mobile devices.
Practical tip: “Hey Mathias, what would you tell administrators who wish to monitor their bandwidth?”
“Instead of trying to measure bandwidth by way of an extra, simulated load, you should have a look around for actions which do that anyway – and then monitor them. For example, when you perform backups, you often put great strain on the bandwidth and can thus easily recognize shortages or bottlenecks.”
Mathias Hengl, PRTG developer at Paessler AG
How do I test my network?
3 questions on network performance
How can I test and monitor my Windows devices?
How can I test my jitter?
A high jitter value is often a good reason for a network performance test. You’ll need a suitable jitter tool to run a jitter test. A single delayed packet can lead to disruptions during a transmission. PRTG monitors the jitter in your network and immediately notifies you in the event of disruptions.

How do I monitor my Cloud services?
Virtual machines and Cloud applications are also prone to their fair share of errors. Individual tests won't tell you much. By keeping a constant eye on your network with a tool like PRTG, you can immediately see if Cloud applications are strained or about to crash. Learn more about Cloud monitoring sensors here.
Other network-related topics for system administrators
With PRTG, you can monitor the performance of your entire network without having to run individual tests. All performance data is presented on an easy-to-read dashboard. Over 95% of our customers recommend PRTG.
LAN and WLAN monitoring
PRTG lets you check the status of your LAN and WLAN at a glance. It keeps an eye on all the activity in your network. Around the clock. Even in distributed networks.
IP SLA monitoring
PRTG monitors quality of service in real time, regardless of the hardware in your network. Our software even monitors Cisco devices at no extra charge.
