The full range of features with every PRTG license

Once you’ve decided upon a monitoring tool, you’re then left with the difficult task of choosing the right modules and features. You may have a limited budget and need to weigh the pros and cons of each feature before making your final selection.
With PRTG, the task is easy: simply determine how many endpoints you wish to monitor and the number of sensors you’ll need to do so. You can upgrade your license at any time just by paying the difference.

 i How PRTG defines sensors

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.

Every PRTG license comes with all the features you'll need for in-depth network monitoring. With WhatsUp Gold, features such as application monitoring, virtualization monitoring and traffic analysis with Flow make the license more expensive.


Monitoring that won’t break the bank


For all-in-one network monitoring software, PRTG is remarkably inexpensive. Many of our customers have enjoyed substantial savings by using PRTG over other monitoring tools.

What’s more, the easy-to-use interface of PRTG saves sysadmins a considerable amount of time that can be used for other things. Since “time is money,” PRTG can help your company save big in just a few months or years.


Create your own scripts or external access with the PRTG API


PRTG comes with its own API. Use the PRTG v2 API to enhance your PRTG with your own sensors or notifications. Create custom scripts or mini probes to get your monitoring data from any platform. With the API, PRTG monitoring can even be accessed remotely. Among other things, you can then incorporate your data into other programs.

Countless customers have praised PRTG for its user-friendly design and intuitive user interface. Even independent software tests highlight the outstanding usability of PRTG. Compared to other monitoring tools PRTG often ranks as the most user-friendly software.
