Mar 29th 2010 - Version 7.3.3.5610/5611
* Overview: This update contains performance optimizations for large installations (>1000 sensors) as well as bugfixes
* New: Optimizations for large installations (thousands of sensors and more)
o On installations with thousands of sensors PRTG's Web GUI felt sluggish under certain conditions
o Thanks to various internal optimizations and an optional "speed mode" (see below) web pages can now be generated 5-50 times faster (compared to V7.3.2 or earlier)
o Our test installations with 10.000 and 20.000 sensors now deliver all web pages (except for sensor lists) in less than 1 second (down from 5-30 seconds)
* New "Speed mode" switch: When enabled (see System Settings|Webserver Settings) the following aspects of the software will change:
o Slower updates for the data displayed in the web interface: It can now take up to 60 seconds for a new sensor state (up/down) to be displayed in the web interface (alerts/notifications will still be sent instantly) (Web GUI und Windows GUI)
o Web GUI does not alert for new todos in the browser window (todo emails will still be sent instantly)
o Web GUI does not dispay the mini graphs for sensors and at the top of the window
o Web GUI does not show sensor-tree related menu items (devices by group, sensors by tag, sensors by type, sensors by group)
* New: "Security Context" for reports (security improvement for reports): You can now select a user account for each report that will be used when creating HTML and PDF reports. Reports will only contain objects (devices, sensors, etc.) which the selected user is allowed to view. By default it is the user who has initially created this report (administrators are able to change this setting).
* Changed: Improved memory handling when saving configuration (some users saw an out-of-memory error while the configuration was written to the disk)
* Bugfix: Removed a potential deadlock in the dependency processing
* Bugfix: For some users the PDF generator and config-check tool did not work due to spaces in pathnames
* Bugfix: Fixed a sporadic handle leak in Custom EXE sensors
September 22nd 2010 - Version 8.1.0.1607/1608 - New Major Version
* Version 8 marks a major leap forward for PRTG. We have implemented great new features including clustering and Google Maps, an updated user interface, a new manual, and many new sensor types. There were more than 1000 changes since version 7!
* New: All-In Licensing for PRTG
o With version 8, Paessler takes a revolutionary step and completely simplifies its licensing model. Using our new add-on-frede software product PRTG 8 you monitor your network without worrying about paying extra money for additional features. Everything is included in one license because we are confident this makes your work easier. Simply choose an installation size for your setup and benefit from the new functionalities PRTG brings to your network.
o See Introducing the New All-In License Model for more information
* New: "PRTG Cluster" Failover Solution
o Up to 5 PRTG instances ("Nodes") work together
o A cluster consists of one primary instance of PRTG ("Master Node") and 1 to 4 secondary servers ("Failover Nodes")
o Objective 1: Achieve 100% uptime for the monitoring solution. Not even a software update causes downtime for a PRTG cluster.
o Objective 2: Automatic failover: If the primary node fails or looses connection to the cluster, another node immediately becomes the master server and manages notifications => Notifications are always sent, even if the primary master has no connectivity or has crashed.
o Objective 3: Multiple points-of-presence monitoring: All nodes monitor all sensors all the time. This means that response times are measured from different locations in the network (LAN/WAN/VPN) and can be compared with each other. Additionally, aggregated up/downtimes can be computed.
o And here comes the best part of this new feature - our customer-friendly-licensing: All PRTG licenses allow you to create a "Single Failover" installation (two installations of PRTG working together) with just one license key (additional license keys are required for 3 or more nodes).
o This means that you don't pay extra to use PRTG's new high-availability feature (compare with other vendors!). We assume that most commercial PRTG installations will be "Single-Failover" installations (1 primary node plus 1 failover node).
o See the blog entry New Features in PRTG 8 - Part 3: Introducing "The PRTG Cluster" for more information
* New: Improved and redesigned web interface: We've rearranged the web interface, added new on-mouse-over features, and redesigned the overall look and feel to make the web interface even more convenient for your daily work. For more information see the blog entries New Features in PRTG 8 - Part 1: Enhanced Web Interface and New Features in PRTG 8 - Part 5: A Little Slideshow
* New: Added a "Mini-HTML" interface for mobile and low bandwidth access designed for iPhone, Android, Blackberry, Windows Mobile, Opera Mini, and even Internet Explorer 5/6 (does not require Ajax/Javascript)
* New: Support for Google Maps in the web interface (maps that show red/green/etc. flags for down/up/etc. devices). Simply enter a postal address, city name, or geotag in the "location" field of groups and/or devices to populate the maps with live monitoring data!
* New: Improved "Maps" feature: PRTG now includes 280 beautifully designed network icons and you can connect map objects with lines that follow their objects when they are moved. With the new editor, PRTG now supports you in creating maps of your whole network structure, even without additional background graphics.
* New chart types: PRTG's charts are now easier to read with the optional new "filled" and "stacked" styles. For traffic sensors the in and out channel can be shown as positive and negative values. See New Features in PRTG 8 - Part 4: New Graph Types for more information.
* New: Native and Agentless Linux Monitoring
o In-depth monitoring of Linux systems without extensive modifications on the clients
o Uses SSH, WBEM, or SNMP for monitoring
o Support for all major Linux distributions and Mac OS X
o See blog entry New Features in PRTG 8 - Part 2: New Native Linux and Mac OS Sensors for more information
* New: Added New Sensor Types
o NTP sensor
o ADO sensor (i.e. support for all ADO compatible databases)
o LDAP sensor
o XEN Server sensor
o WMI Hyper-V Virtual Storage Device sensor
o WMI Terminal Server sensor
o WMI Share sensor

o VMware Host Hardware sensor (using WBEM)
o WBEM Custom Sensor
o See New Features in PRTG 8 - Part 5: New Sensor Types for more information
* New: New, completely rewritten manual available in HTML and PDF formats (PDF version has more than 600 pages)
*
New: HTTP sensors and HTTP notifications now offer proxy support
*
New: Reporting is now fully decoupled from the web server and user interface, so report generation no longer affects user experience. This allows us to ease the minimum interval limits for reports: reports with 1 minute interval can now be created for up to 40 days instead of one day, 1 hour reports are possible for up to one year now.
* Improved: Email notifications: Notification HTML emails now look great on most email clients.
* Improved: Notification summarizing (to avoid email floodings)
* Improved: WMI connection management
* Improved: API - Many new features have been added to make it easier to create your own custom sensors and scripts.
* New: Added a graphical visualization of sensor dependencies
* Improved: Monitoring scheduler now avoids load peaks on monitored devices caused by simultaneous monitoring requests

* More than 1000 changes, features and bug fixes since version 7
Release Notes and Changes
January 17th 2011 – Version 8.2.0.1898/1899
Important: During the upgrade process you may see a longer downtime than usual! During the update from a previous version three databases must be converted. Hence, the monitoring downtime during the first startup of PRTG after the upgrade can be up to a few minutes—depending on your configuration, the amount of data and your system performance (see first list item for details).
* [Core Server] New database format:
o We implemented a new, faster database system for log, ToDo, and Toplist data. This new system is much faster and will provide a much swifter user experience, especially on systems with 500 and more sensors. In our tests we found that it can be up to 300 times faster, depending on your system and configuration
o After upgrading to V8.2.x or later your previous databases will be converted during PRTG’s startup - which can take between a few seconds and a few minutes. Only the potentially huge multi-gigabyte Toplist databases will be converted in the background after the startup, as soon as the monitoring process has been restarted. During the conversion you may see drops of Toplists (gaps in your Toplist data) whenever the system performance is not capable of supporting simultaneous conversion and monitoring. Note: The old database files will be deleted 70 days after the database upgrade.
o For detailed information, please see Knowledge Base article: Introducing a New Database Format with PRTG 8.2
* [Sensors] Important change for Ping and Port sensors:
o Their time values no longer cover the DNS resolution in their measurements, now values are analogous to the Windows built-in Ping command. Depending on the type of DNS entry used for the parent devices this can change the values dramatically to smaller values. For devices that are set up using IP addresses the values do not change at all.
o For detailed information, please see Knowledge Base article: Behavior of Ping and Port Sensor Changed
* [Auto-Discovery] Massive upgrade of the Auto-Discovery system:
o Auto-Discovery now covers 95% of the available sensor types, depending on your network you may see 20-50% more sensors during an auto-discovery scan.
o Added various options to enter IP ranges for auto-discovery, including Class A address ranges and IP lists. Note: Only subnets with up to 65536 IP addresses can be discovered.
o Added 5 new device templates to the Auto-Discovery system, including “Linux SNMP”, “Server RDP”, and “XEN Server”.
o Users can now select the time of day when daily, weekly, and monthly auto-discoveries are performed (default is 4 a.m.).
o WebGUI shows a note about potentially degraded performance while auto-discoveries are running.
* [Device Templates] Massive upgrade of the device template system:
o Now all sensors that make sense to be stored in device templates will be used (covering about 95% of available sensor types).
* [Sensors] 3 new sensor types:
o New DHCP sensor checks whether a DHCP request is answered by a DHCP server in the network
o New SSH VMware ESX(i) Disk Sensor monitors disk space on attached storage of VMware ESX and ESXi servers via SSH
o New jFlow V5 Sensor supports Juniper jFlow (version 5) monitoring. Note: Sensor does not support sampling yet, please disable sampling on the device (see user manual).
* New: [Sensors] Added an alternate connection method for VMware sensors (.NET required on the probe system), during testing we saw some situations where the alternate connection worked more reliably than the default one.
* New: [Sensors] EXE/Script sensors now support environment variables (all environment variables have a "prtg_" prefix)
* Changed: [Sensors] The TCP port can now be selected manually for MySQL sensors
* New: [Core Server] We implemented various performance enhancements that will mainly be visible on installations with 500 or more sensors. Many web pages created by the web server are now up to 100 times faster than before (on systems with thousands of sensors).
* New: [WebGUI] Submit buttons on setting pages are now always scrolled into view automatically
* New: [WinGUI] Various improvements of the WinGUI, including the option to select the default browser engine to open web pages.
* New: [Reports] Reports with tables now include a list of down- and uptimes of a sensor
* New: [WMI] Yet again, another bunch of WMI improvements, mainly for systems with many WMI sensors (500 or more)
* Changed: [Cluster] "Simulate Error" now propagates across a cluster
* Bugfix: [WebGUI] Fixed a potential Cross Site Scripting (XSS) vulnerability
* Bugfix: In total more than 300 bugfixes and improvements are included in this build
January 25th 2011 – Version 8.2.1.1930/1931
Important: During the upgrade process you may see a longer downtime than usual! During the update from any previous version lower than 8.2.x three databases must be converted. Hence, the monitoring downtime during the first startup of PRTG after the upgrade can be up to a few minutes—depending on your configuration, the amount of data and your system performance (for details, please see information about version 8.2.0.1898/1899 below).

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
Video—Our CEO presenting the updated interface
Read about it—An article in our blog introducing the new interface in its historical context
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 14 or later (recommended), Firefox 10 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 gages. 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
New default colors for graphs
Changed appearance of buttons, tables, etc.
New interactive breadcrumbs for an easier navigation
QR codes for easy access to the direct URL of your monitoring objects on your mobile
Many other tweaks here and there
The Enterprise Console profits from the changes, too - whenever it embeds parts of the WebGUI
New [MobileGUI]: Revised Mobile Web GUI: Easier to read and new look&feel
New [Core]: Similar sensors analysis: PRTG automatically detects similar sensor data and shows matches in your sensor's "Overview" tab. This function is totally independent from sensor types and uses pure mathematics for heuristic calculation. (You can configure this feature in the "System & Website" system settings.)
New [Graphs]: Display of sensor limits: If you set a limit in a sensor channel (for example, an upper or lower warning limit, or an upper or lower error limit), these limits will be shown in the new sensor gages as yellow and red areas. Additionally, yellow and red areas can be shown in graphs. In order to show the colored areas in graphs, you must configure your graph to show one sensor channel only. Otherwise the limit areas will be hidden in graphs. For details, please see our knowledge base at http://www.paessler.com/knowledgebase/en/topic/48463

Changed [GeoMaps]: When entering a new "Location" for a probe, group, or device, PRTG now tries to resolve a street address to geo coordinates not only via Yahoo, but also via MapQuestAPI and Nokia. For details, please see http://www.paessler.com/knowledgebase/en/topic/35823
Known issues:
[WebGUI]: Please empty your browser cache if you experience display issues when loading the new web interface for the first time
[WebGUI]: The dependency display ("Devices | Dependencies") is currently not available. A similar view will return with future versions.
[UI]: The Czech and Chinese language versions are not updated. You may see a lot of strings in English language when running the web interface or the Enterprise Console in these languages.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!
