July 8th 2013 - Version 13.3.4.2478/2479 [Stable]

In this version we implemented a lot of improvements, ten new sensors, and several bugfixes. For details, please see below.

Core Improvements

  • Improved [Core]: Improvement of overall speed of the PRTG web interface and the Enterprise Console by significantly improved handling of user sessions. You will especially experience increased speed if many users access your core server at the same time.
  • Improved [Core]: General improvements to the SNMP monitoring engine
  • Improved [Core]: Enhanced security with better protection against external connection attempts.
  • Improved [Core]: After a core server restart PRTG now waits longer for an IP address to be assigned to the server. This will solve issues with PRTG's web server switching to localhost after restarts.
  • New [Core]: New registry key option to centrally disable automatic numbering in PRTG (for example, automatic numbers attached to sensor names when using the auto-discovery). For details, please see our knowledge base article.

New Sensors and Sensor Improvements

  • New [Sensors]: The „Application Performance Sensor" (currently to be considered beta) is an experimental sensor that can measure the performance of network applications by looking at the timing of network packets going into and coming out of a server using packet sniffing. PRTG analyzes network packets and measures the time between requests and responses. This allows you to monitor the performance of a server/service without actually having direct access to neither the client nor the server (works with TCP-based protocols that initiate a new TCP session with each request). Please give us feedback for this sensor type!

Please read carefully!

 In these release notes:  New | Changed/removed | Known issues

This release contains the code of focused development work from the last five months. The most obvious change: We have revised the entire web interface. It now reacts almost instantly, and with new control elements and colors, data is now easier to consume. Plus, we added a lot of new features here and there to make PRTG even more convenient to work with. For detailed information, please see

Some of our users use custom CSS, HTML, or their own icons to change the look&feel of PRTG's web interface and/or reports. Please note that this kind of customizations will be disabled after an update to the current version and you will have to rework them. For details, please see https://www.paessler.com/knowledgebase/en/topic/44703

Supported browsers are Chrome 27 or later (recommended!), Firefox 21 or later, and Internet Explorer 9 or 10.

The Changes in Detail:

  • New [WebGUI]: Completely revised and updated look&feel of the PRTG Ajax Web GUI
    • Faster loading times and almost instant reaction on clicks
    • All settings loaded in layer popups so you never lose the context of your work
    • New view modes for Libraries: Sunburst, Tree Map (as known from the device tree)
    • Revised devices overview page: Extra display of high-priority sensors, in different sizes, for sensors with 4 and 5 star priority
    • Revised sensors overview page: Graphical display of sensor channels with gauges. For xFlow and packet sniffer sensors, the "Toplist" graphs are now shown in the "Overview" tab. Edit channel settings directly on a sensor's "Overview" tab.
    • Redesign of built-in dashboards, sitemap, and top 10 lists
    • New sensor comparison page: compare several sensors at a time
