PRTG vs Checkmk – which tool is better?

Both PRTG and Checkmk are network monitoring tools that let you keep an eye on your entire IT environment and ensure your business operations run smoothly. But upon closer inspection, we notice some differences between the two tools.

If you're looking for an alternative to Checkmk, then you should definitely check out PRTG. On this page, we’ll explain what makes PRTG stand out from Checkmk.


What is Checkmk?

Checkmk is a network monitoring tool that provides for comprehensive monitoring of IT infrastructures. Checkmk runs exclusively on Linux servers and comes in a variety of versions, including the open-source Raw Edition (CRE) – which is based on Nagios –, the Enterprise Edition (CEE), and the Managed Services Edition (CME).

Why PRTG is the perfect alternative to Checkmk

 i What 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.

Tried and tested tool developed by an experienced team

Paessler has been making life easy for IT administrators for over 20 years. Today, more than 500,000 admins worldwide use PRTG. In our Case Studies, you'll find reports from companies from a wide range of industries that describe how they use PRTG and how the software helps them improve their business processes. PRTG also consistently ranks first in independent tests.

Our dedicated team of developers work hard to ensure each new version of PRTG is better than the last. In addition to making improvements to the software, the team incorporates new sensors to allow for the straightforward integration of devices and services.

Flexible licensing

Flexible licensing model based on the number
of sensors

Every PRTG license comes with the full range of features, which means you’ll never have to pay for add-ons. License prices are based on the number of required sensors.

With Checkmk, on the other hand, prices are based on the number of services. Each service is considered a separate part of the monitoring (e.g., the monitoring of CPU). At first glance, Checkmk seems to offer more value for the money. However, if you compare typical use cases and take into account that one sensor from PRTG usually corresponds to several services from Checkmk, the price of PRTG and Checkmk is about the same.

high customizability

Easy setup, high customizability

PRTG is set up in a few quick clicks. Its smart Auto-Discovery feature automatically adds relevant parts of your network to the monitoring environment. Of course, you can also configure PRTG in countless different ways to tailor the monitoring tool in accordance with your network and needs. With PRTG, you can even create your own custom sensors.

With Checkmk, setting up and adding plug-ins and monitoring features is usually a bit more complicated. Many plug-ins require the installation of an agent and are often difficult to configure.


Intuitive and user-friendly

Monitoring software only saves sysadmins time when it’s easy to use. PRTG is designed with an intuitive user interface that provides for excellent usability. With PRTG, sensors and measurement points can be added with just a few clicks. Easy-to-read illustrations (e.g., the “Sunburst View”) let you determine the status of your network at a quick glance.

operating system

Compatible with any operating system

Checkmk can only be used on a Linux server. PRTG, on the other hand, can be used on any operating system (depending on the version): You need a Windows server to install PRTG but with PRTG Desktop Client, you can also manage and control your monitoring environment in macOS or Linux. PRTG Hosted Monitor can be used on any computer connected to the Internet.

Finally, PRTG also comes with mobile apps for your smartphone, smartwatch, or tablet.
