For a few days now, the PRTG release 19.2.49 has been available for download on the stable release channel. The current release contains a lot of improvements, including improved performance of the PRTG core server, the PRTG Desktop integration, news about .NET 4.7.2 requirements, and much more.

So, let's have a look at the features of the new version.

PRTG Desktop Is the New Enterprise Console

Perhaps you've already noticed it here on the blog: the official successor to the PRTG Enterprise Console is called PRTG Desktop, and recently left beta status. If you'd like to read more, have a look at these blog articles:

In the PRTG web interface you have the option Desktop Client Apps listed in Downloads and Tools. There you will find more information about the PRTG Desktop app and you can open the download page directly. In addition, you will find a link to this page on the Windows desktop of your PRTG server.


9 New States for the SNMP Synology Logical Disk Sensor

Synology has recently introduced a revised MIB file, which now includes 21 different states instead of 12. This improvement results in the following shiny new sensor gauge.


It represents all possible states:

Up status Normal, Parity Checking, Data Scrubbing, Deploying, Undeploying, Mounting Cache, Unmounting Cache, Expanding Unfinished SHR, Converting SHR to Pool, Migrating SHR to Pool, Migrating SHR1 to SHR2
Warning status Repairing, Migrating, Expanding, Creating, Syncing, Assembling
Down status Deleting, Canceling, Degrade, Crashed, Unknown

Find more details about the SNMP Synology Logical Disk Sensor in the PRTG manual.

Windows Process Sensor Now Supports 64-Bit

The new version allows you to monitor the memory usage of Windows processes, even if they consume more than 4GB of memory. The channel "Private Bytes" shows values above 4 GB, which were previously just cut off.

.NET Version 4.7.2 for EXE-Based Sensors

Keep it modern, keep it secure. PRTG now requires .NET version 4.7.2 installed on all computers running a probe for all sensor types that require the .NET framework. You will receive a ToDo ticket in PRTG for each affected probe if .NET 4.7.2 is missing and you will not be able to add .NET sensors anymore in this case. Running .NET sensors will show a down status with error code PE104 after you have installed the PRTG update.

For all important information about the .NET Framework in connection with PRTG we have summarized a knowledge base entry for you.

Code Improvements under the Hood

As with any multi-faceted software whose range of functions grows steadily over the years, modernization and modularisation measures under the hood are necessary from time to time. PRTG is currently still in such a modernization phase. Several things are currently being prepared to successfully take PRTG to the next level together with you. Our developers are working on countless measures to improve the source code and the functions, which you won't necessarily immediately notice in the front-end of the software.

Some More Improvements and Fixes

PRTG shows the user account that acknowledged the down status of a sensor again. As usual, the name will appear in the message as well as in the log of a sensor in status Down (Acknowledged). In PRTG version 19.1.48, the name of the acknowledging user account was missing.

If you are using PRTG with the Dutch language file, there is also reason to be happy. We have made major updates to the Dutch language file and improved the consistency of the language terminology.

We've also fixed some bugs on sensors, the server, and the web interface. See the PRTG release notes page for details and all other changes in the current version.
