PRTG Network Monitor 7.1 - Official Release
This is an exciting day for everybody here at Paessler AG: After seven months of hard work we have finally uploaded the V7.1 release binaries of PRTG Network Monitor. This new version contains more than 800 new features, enhancements, changes, and bugfixes since version 7.0.9. Upgrading to the new version is recommended for all users of previous PRTG versions.2009-Mar-27
New Features in PRTG 7.1 (Part 7): "Official Support for PRTG Virtualizing"
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. Virtualization has become a fundamental part of the IT eco-system. Many of our customers have already moved or will soon move considerable parts of their computer systems into virtual servers. Of course we also use virtualized systems heavily in our own software test lab together with a lot of real hardware. With version 7.1 we now officially support running PRTG Network Monitor on virtualized platforms. PRTG already supports native monitoring of VMware servers since last October. Now it is a logical step to support running PRTG virtualized, too.2009-Mar-26
Almost There: Announcing the Release Candidate of PRTG 7.1
The official beta test for version 7.1 of PRTG Network Monitor is approaching its final stage. Today we have uploaded the Release Candidate! During the public beta test (ongoing since January 30th 2009) PRTG Network Monitor version 7.1 was thoroughly tested by our own team as well as hundreds of beta testers. Internally we called this intense test project the "mother of all software tests" and we are quite satisfied with the results: we are now convinced that the upcoming release of PRTG 7.1 is- 1. the best software we have ever created and
- 2. the best tested software we have ever released.

How PRTG computes CPU Index, Traffic Index and Response Time Index for your network
In order to provide graphs that show a quick status overview of your complete network (or a part of it) PRTG computes so-called "index" values based on the measurements of all sensors. The "index" graphs are synthetic values between 0% and 100% based on current sensor measurements and their historic maximum values. The calculation of these index values works similar to a stock index which is computed using the current values of selected stocks.
For each group and device PRTG shows four values in a graph.

New Features in PRTG 7.1 (Part 6): "SNMP Trap Notifications"
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. In PRTG V7.1 we have added a new option for notifications: If an event occurs (e.g. a sensor's state changes from up to down) PRTG can now send SNMP Traps to a computer where a so-called Trap Receiver is listening. Trap receivers usually store these messages for later analysis and/or forward traps to the administrators using other means of alerting.2009-Mar-24
New Features in PRTG 7.1 (Part 5): "Automatic Probe Updating"
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. Another new break-through feature of PRTG 7.1 is the automated probe updating. PRTG users who have set up one or more remote probes in their configuration will love this feature.2009-Mar-23
New Features in PRTG 7.1 (Part 4): "Email Round Trip Monitoring"
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. Another interesting new feature in PRTG 7.1 is "Email Round Trip Monitoring". Two new sensor types ensure the end-to-end delivery of emails and make it possible to monitor availability and performance of a complete email delivery process.

New Features in PRTG 7.1 (Part 3): "Copying Devices by Cloning or Using Device Templates"
During the beta test of PRTG Network Monitor 7.1 I am posting a number of blog articles about new features in the new version. After configuring a device with one or more sensors there are two options to copy it:- Cloning a device: Is the best option to simply duplicate a device only a few times with all its sensors and settings.
- using a device templates: Is the preferred option if you have many similar devices and if you do not want to create all devices manually through the web interface. This is also the better option if the devices do not have the same number of ports.

Beta 3 (aka "Final Beta") of PRTG Network Monitor 7.1 is available
Today the final beta of PRTG 7.1 is available. This new version includes more WMI improvements, again more speed improvements for the web interface as well as many other changes. The next step on the way to the official release of PRTG 7.1 will be Release Candidate 1, scheduled for next Monday. Here is our current roadmap:2009-Mar-16
What to do when PRTG's ESX sensors show "Connection hangs. Check SSL on VMware server, then restart probe." message
When monitoring VMware ESX 3.5 servers with PRTG 7 we have seen situations where the HTTPS webserver of the ESX server crashes (i.e. the management interface is no longer accessible). In PRTG 7 all ESX sensors show a red alarm state as well as the message "Connection hangs. Check SSL on VMware server, then restart probe." In order to revive the web server on the ESX server please perform the following steps:2009-Mar-16
