  • Primarily just a sniffing tool

  • Individually extendable

Think twice

Think twice

Ethereal is open source and free - but does it fit your needs right from the start?

You surely need much more advice and consulting than using PRTG. Especially in the long run, PRTG is much cheaper.

Looking for a flexible Open Source Network Software like Ethereal?

Think twice 


PRTG is not Open Source, but one of the most flexible tools in the market.


PRTG: The swiss army knife for sys admins

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

  • HTTP API: Access monitoring data and manipulate monitoring objects using HTTP requests
  • Custom Sensors: Create your own sensors for customized monitoring
  • Custom Notifications: Create your own notifications to send alarms to external systems
  • New REST API Sensor: Monitor almost everything that provides XML or JSON


So, PRTG is more flexible and cross-functional than Ethereal.
