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 http://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
    • Paessler blog integration: Read the latest news from the Paessler RSS feed on the PRTG login screen

  • New [Cluster]: Users can now select which cluster nodes are used to monitor a specific group/device (e.g. when not all cluster nodes can connect to a subnet or VPN)
  • New [Sensors]: MS Exchange Transport Queue Sensor
  • New [Sensors]: Added a third option to the HTTP Full Page sensors. With this new third option you can enable screenshotting of each sensor run. You can either save only the latest screenshot, or each screenshot of this sensor. The image files will be stored on the probe system (user can set the number of days until the files are purged, creates a lot of data on the disk). This option needs plenty of CPU cycles and should not be used too heavily.
  • New [WebGUI]: Added an experimental feature that allows a user inside the WebGUI to install a remote probe on a Windows device in the sensor tree (Context menu of devices, device tools, install remote probe). The remote probe is automatically installed and configured. Afterwards it will show up at the bottom of the sensor tree and the user must approve the probe. Then sensors can be set up as usual. This is a great way to circumvent WMI or other connectivity problems by running sensors directly on the device.
  • Improved [Core]: When Active Directory integration is used all requests to the AD servers are now cached for one hour. Before this caching was implemented large and/or slow AD environments could potentially slow down PRTG’s user interfaces. If a password is changed in the AD you must either wait for 1h or clear the cache manually (on the status page).
  • Improved [Graphs]: Graphs now display the applied averaging interval at the bottom right
  • Improved [Sensors]: Added timestamp into emails of email round trip sensors
  • Improved [Sensors]: SNMP Custom String now supports RegExp
  • Improved [Sensors]: When devices need extensive time to answer WMI requests the sensor will be labeled “sluggish” because these sensors can actually affect the performance of the complete WMI system for all devices. We recommend to either install a probe directly on these devices or at least move these sensors to a dedicated probe
  • Changed [Sensors]: The Windows Scheduled Task sensor now supports tasks in sub folders. Note: When monitoring target systems which run Windows 2003 or Windows XP, the sensor might stop working under certain conditions.
  • Improved [Remote Probes]: More stability for Remote Probe connections
  • Bugfix [Sensors]: Windows Print Queue Sensor now accepts ‘Min. Print Job Age’ setting

  • Various minor improvements for the WebGUI, Core Server, Enterprise Console, and manual

July 19th 2012 - Version 12.3.1.2365/2366 [Stable]

  • Bugfix: Added a workaround for a browser bug that was introduced with Firefox 14.0.1 yesterday (FF14 currently can not display curved texts in PRTG's sunburst views of the device tree)
  • Bugfix: In the "SNMP Compatibility Options", the "Overflow Values" option did not work as expected (functionality was reversed). We corrected this. From now on, "Ignore overflow values" will actually ignore overflow values, whereas "Handle overflow values as valid results" will show the (possibly incorrect) value reported by the device. We apologize for the inconvenience caused by this bug! For more details, please see our knowledge base article. 
  • Note: We recommend using SNMP v2 if supported by your devices, in order to generally avoid 32bit counter overflows altogether. In the "Credentials for SNMP Devices" section of the PRTG device representing your switch or router, set the SNMP Version to "v2c". Then, please add your SNMP sensors anew. Existing sensors will continue to use the former SNMP version setting. Historic data cannot be transferred to the new sensors, but you can pause the old sensors to keep their data.

June 28th 2012 - Version 12.2.2.2210/2211 [Stable]

  • Bugfix: During an update from V9 to V12 custom SSL certificates of the web server were not migrated properly (only if autoupdate was used)

June 20th 2012 - Version 12.2.2.2156/2157 [Stable]

  • Workaround [Sensors]: Some users experienced elevated WMI delays and gray sensors throughout their installations. After intensive investigation we found that new functionality inside the WMI Service sensor caused these effects - but only in very few situations/networks. The new features are now disabled by default and we recommend all users to upgrade to version 12.2.2. We will further investigate the root cause.
  • Bugfix [Core]: "Acknowledge" an alarm did not override previous "Acknowledge Until"
  • Bugfix [WebGUI]: Sunburst view did display properly on Firefox 13
  • New [WebGUI]: Maximum zoom level of geomaps can now be set in customerscript.js: _Prtg.Core.objects.geomapMaxZoomLevel = 19;
  • Several bugfixes and improvements
