We updated the German, Spanish, French, Portuguese, Russian, Japanese, Chinese and Dutch language files.
We fixed an issue for the PRTG application server that occurred in the previous Preview version 24.3.98.1197 where you could observe an excessive increase in memory consumption in the Application Server Health (Autonomous) sensor. The issue occurred in connection to the newly introduced endpoints for sensor channel settings.
Please note that a certain rise in memory is noticeable and expected due to this new endpoint but should not exceed more than 70kb per channel.

Preview 24.3.98.1205
With this PRTG version we provide various fixes to improve security and stability.
We improved the error message for certain sensor types that appears when you need to check credentials or logfiles for a sensor. Affected sensors are AWS sensors, EXE/Script sensors, Zoom sensor, Veeam sensors, OPC UA sensors and Cloud sensors. The previous error message did not indicate that the setting for Store Result is not enabled by default and that you first need to enable it and run a rescan of the sensor before you can check the logfiles. An example error message now displays The sensor could not authenticate with AWS. Check your credentials for AWS or select 'Store result' under Debug Options | Result Handling in the sensor settings, rescan, and check the \\Logs\\sensors subfolder of the PRTG data directory on the probe system.
Various other minor fixes and improvements, updated user manual.
We updated the information for Possible Values in the section Sorting and Advanced Filtering in our user manual.
We fixed an issue for API keys that did not display the correct Access Level when the user to whom the API key was assigned was deleted or moved from the corresponding user group. The API Key List has now an additional column Effective Access Level that displays the up to date and in use access level for the relevant user.
We fixed an issue where a Core logfile was created on a remote probe after you started the Administration Tool on that relevant remote probe. The logfile was created under C:\ProgramData\Paessler\PRTG Network Monitor\Logs\core.
We fixed an issue for the HPE 3PAR Drive Enclosure sensor that led to several issues when you used multiple sensors of that type on the same device on the same probe. The sensors would report an error with the message that the session could not be started (Cryptographic functions must be set on at least one blocksize). In some cases the sensors would work again if you enabled the Store Result function, but then ran into an unknown state if you disabled it again.
Important:This fix introduces a maximum number of parallel connections to the same device with same credentials. If that limit is reached then you will receive the error too many concurrent connections. This limit is currently hard-coded to 20 concurrent connections with the same credentials/device combination within the HPE 3PAR Drive Enclosure sensor. This issue also occurred on the Multi-Platform Probe.
Your Microsoft Azure and Microsoft 365 sensors will now use correctly proxy settings when you have configured those on the relevant device. Previously, the proxy settings were displayed correctly in the logs but disregarded for Azure AD login.
We fixed an issue for the OPC UA Custom sensor that reported an error with the message No Value is set in certain cases. The issue could happen in cases when the DisplayName, BrowseName or Description attribute was empty.
We fixed an issue for the WMI Event Log sensor where the sensor did no longer display a sensor event message for triggered events. You could observe the missing information in the Message column of the Log tab of the sensor as well as in the sensor status bar below the sensor name. The sensor also only reported the status OK in certain cases.
You will notice a higher memory usage on your system when you run the PRTG application server and when you update to this PRTG preview version 24.3.98.1197. The issue occurs because a change for channel settings in the PRTG API v2 requires more memory. We are working on a fix for this issue with high priority.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 24.3.98.1197
We improved the text message that is displayed when you are logged out due to inactivity. Previously, the message displayed was Your have been logged out due to inactivity.
You are now able to edit the settings of a sensor channel via the PRTG new UI. On a channel card of a sensor you will now see an additional Actions button: Edit Settings. This button will open a new dialogue window where you can make changes to the selected channel. If you do not change anything or if you enter invalid values, the Save Settings button will stay inactive.
The Script v2 sensor left its BETA status with this PRTG version and is now fully supported. We introduced this sensor type as experimental sensor with PRTG version 23.1.82.2074. The sensor executes a Python script that returns data in JSON format and shows the exit code. This way you can create your own custom script sensors that may not be available in PRTG by default. For available example scripts and how to use them, please see the Knowledge Base article: I want to use the Script v2 sensor example scripts. What do I need to know?
You are now able to delete created API keys under Account Settings in your PRTG Setup via multi-edit selection. Previously, API keys could only be deleted individually. For every API key that you delete, PRTG will add an entry in the History tab of your User Account settings.
You can now add multiple subnets to the auto discovery setting. If you want to include multiple addresses and subnets, enter them in the field IPv4 and Subnet (IPv4) as a list separated by a comma. Please note that this feature applies only for IPv4 subnets and does not support IPv6.
We updated the available lookup values for NetApp v2 sensors that were not supported in previous PRTG versions before. For example, the NetApp System Health v2 sensor now supports the values Tri Path, Tri Path HA and Virtual state for the status Up in the Storage Configuration Path channel. Other NetApp v2 sensors that have now addtional supported lookup values are NetApp SnapMirror v2 for the channels Mirror State and Policy Type and NetApp NIC v2 sensor for the channel State.
With this PRTG version we introduce a new setting Microsoft Azure Management Endpoint in the Credentials for Microsoft Azure. This setting allows you to change the API endpoint for your region that can differ from the default URL management.azure.com to use Microsoft Azure sensors, such as Microsoft Azure SQL Database sensor or Microsoft Azure Storage Account sensor in your environment. Please note that this setting is locked by default and can be edited upon request.
Various other minor fixes and improvements, updated user manual.
We updated the German and Spanish language files for certain selected sensor types.
We updated the versions supported for Veeam sensors (Veeam Backup Job Status sensor, Veeam Backup Job Status Advanced sensor) regarding the Veeam Backup Enterprise Manager.
We removed the following libraries from the Sensor System since they are no longer needed: MongoDB.Bson.dll, MongoDB.Driver.dll, Mono.Security.dll. The libraries were a leftover from the MongoDB System Health sensor that we announced as deprecated with PRTG version 16.2.23 and finally removed from PRTG with PRTG version 16.3.25.
We fixed an issue where the PRTG Core server generated a high CPU usage when you used an API call for a historic data report with a negative average interval avg=-[interval]. PRTG considered the API call as invalid in these cases and could not respond what caused a timeout and thus lead to a higher usage in CPU.
We fixed an issue that occurred when you updated to the previous PRTG version 24.2.94 where in certain cases the PRTG core server service could not start and could not be restarted as well. The PRTG web interface would report timeouts or load endlessly after login. In some other rare cases, the update to PRTG version 24.2.94 was successful, however, the web interface performance was very slow in loading pages and you also could observe ReadLock entries in the core.log. Rolling back to the former PRTG version 24.1.92.1554 would solve the issue.
We fixed an issue where the installer window for a remote probe could not be closed with the x button in certain cases. The issue happened when you changed the Setup in your PRTG installation under Probe Connection Settings to allow probe connections to the core server when you already executed the remote probe installer. The installation process could be finished successfully, however, you were not able to close the dialogue window of the remote probe installer.
We fixed an issue for the AWS EC2 v2 sensor that reported the error message Channel with ID [ID ]is not defined in very rare cases because the sensor sometimes received zero 0 values for the DiskReadOps (Average) metrics. Since the sensor expects values for every scan, it reported the mentioned error when it received 0 values. The issue occurred when you used the sensor on a Linux instance but could also occur on a AWS EC2 Windows system.
Running an auto-discovery with a device template that includes the following sensor types will now add these sensor types to your device as expected: Windows Print Queue sensor, VMware Datastore (SOAP) sensor and SMTP&IMAP Round Trip sensor.
We fixed an issue for Microsoft Azure sensors, like Microsoft Azure Storage Account sensor, Microsoft Azure SQL Database sensor or Microsoft Azure Subscription Cost sensor, where the Result of Sensor log reported the error The sensor could not get a response from the server. 400 (Bad Request) in certain cases. The issue occurred when you used a scanning interval of 12h or 24h because the sensor used an invalid format that could not be handled by the Azure REST API.
You can now create a device template from a device that includes a POP3 sensor and the sensor will be added to the device afterwards. In previous PRTG versions, when you opened the dialogue window Create Device Template, the sensor was not added to the relevant device after you received the success message Create Template Results, although the sensor was listed in the results.
We reduced the possibility of a higher memory consumption and a memory leak on the probe that occurred in certain cases when you ran SNMP and HTTP/HTTP Advanced sensors on your local or remote probe. Eventually, the probe would report the status disconnected. Restarting services only helped for a certain while in these cases.
We reduced the risk for PRTG logs to get a large file size when WMI exceptions occur, especially for the ProbeWMI.log. This could lead to a full disk in certain cases since the file size increased very quickly and therefor result in a not working probe system in the worst case.
We adapted the information for Result Handling in the Debug Options help tooltip so that it displays the correct file name and subfolder where the sensor result is stored. The file name now is UDP Debug Port [Port][Date].log in the Logs/debug subfolder for both sensor types.
We fixed an issue where the PRTG MultiBoard ran into a timeout in the previous PRTG version 24.2.96.1315 when you used the Template Transfer (BETA) feature in order to move a custom device template from one PRTG server to another. Please note that this feature is only available when you run PRTG with a Paessler PRTG Enterprise license.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 24.2.97.1683
You can try out the experimental Cisco WLC Access Point Overview sensor (BETA) that monitors your access points that are connected to your Cisco Wireless LAN Controller (WLC). The sensor will show the following columns during sensor creation: MAC address, Name, Location, State for the access points as well as IP address, Model, Serial Number and Number of Slots. The Number of Slots represents the number of radios and antennas for an access point. The sensor comes with the channels Operational Status, Admin Status, Max Rx Utilization, Max Tx Utilization, Max Channel Utilization, Client Count and Client Count with Poor SNR (Signal to Noise ratio).
Various other minor fixes and improvements, updated user manual.
We updated the German, Spanish, French, Dutch, Portuguese, Japanese, Chinese and Russian language files.
We updated the German and Spanish language files for certain selected sensor types.
You can now filter for a specific sensor type when you select Add Library Node for your library and when you choose the option Show a collection of filtered sensors and Show only specific sensor types for that node. In previous PRTG versions, when you filtered for the sensor type SSL Certificate sensor, the SSL Security Check sensor would be added to the node as well, for example.
We fixed an issue with PRTG stable version 24.2.94.1400 where the Probe update to this PRTG version failed and therefore the Probe service(s) did not start in some cases. PRTG would report an error message like
Your Active Directory Replication Errors sensors will now work properly again when you update to this PRTG version. In the previous PRTG versions, the sensor reported the error Replication Neighbor cannot be found in some cases when you updated to PRTG version 23.1.82.2074 and higher. The issue occurred because we improved the method of password transmission for certain sensor types, which could not be handled by the Active Directory Replication Errors sensors correctly.
We fixed an issue for the HTTP v2 sensor that appeared during sensor creation process on the Add Sensor dialog. In the section for HTTP Specific the default URL value would display https://%%host/ instead of https://%host/. This issue also occurred when you added the sensor to your Multi-Platform Probe.
We fixed an issue where in some cases the remote probe reported the status disconnected from time to time when you moved Flow sensors to that specific remote probe or when you had Flow sensors running on that specific remote probe. The issue occurred for sensors, like NetFlow and sFlow sensors, for example. In the Probe.log you could also observe access violations for the FlowProcessor or the FlowSender.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 24.2.96.1270
We fixed an issue for the SNMP Traffic v2 sensor that could not be created in some cases and reported the error message The target system did not return a result for the requested OID.
You can now add and edit under Notification settings your notification Schedules, notification Contacts and notification Templates. Please note that this feature is not available on mobile view.
You are now able to clone objects (group, device, sensor) via PRTG APIv2 POST request and the endpoint object name/id/clone. The settings of the cloned object will have the same settings as the original object. A cloned sensor, for example, has the default name 'Clone of
With this PRTG version we provide various fixes to improve security and stability.
We improved the delivery time for HTTP notifications that took longer in certain cases in the previous PRTG versions when you used a HTTP target URL in the Execute HTTP Action section of the notification template. This issue occurred because the PRTG fallback handling for SSL still tried to establish a TLS secured connection what did not lead to an error but to a longer waiting time for PRTG.
You are now able to create the Ping v2 sensor via device template if you select the option Create Device Template on a device where you can select the Ping v2 sensor in the Create Device Template dialogue window. The Ping v2 sensor left its BETA status with PRTG version 24.1.92.1554 and is now fully supported. This feature also works on a device for the Multi-Platform Probe.
You will now receive a proper error message in the probe adapter log when your NATS server for connection does not offer a secured TLS connection but PRTG is configured to connect with TLS in the Multi-Platform Probe Connection Settings.
Various other minor fixes and improvements, updated user manual.
We fixed an issue where the button Contact Support was missing in the help bar and also in the Support section on the PRTG Setup page when you ran PRTG with a trial license. This issue also affected Paessler PRTG Hosted Monitor.
We fixed an issue where the API call for api/health.json reported wrongly a disconnected Cluster probe although the probe was connected at this time. You could also see this behavior on the System Status page in PRTG under Probes where the Cluster Probe was reported as not connected yet.
We fixed an issue for public maps access that allowed users to see objects in the device tree despite of their assigned security context when you had two or more public maps open in a tab for map rotation view.
You will no longer receive an error when you click on the button Stop Service or Start Service (ignore changed settings) for the Core and Probe service in the PRTG Administration Tool when you run it as a 64bit version on your system. This issue occurred in the previous PRTG stable version 24.2.94.1400 but did not happen when you run the PRTG Administration Tool in a 32bit mode. The reported error message in this case was One or more required program components of PRTG (PRTG Server.exe, PRTG Probe.exe) could not be found! Please re-run the installation program.
You will now receive proper results from our Help documentation when you click on the More button on the Search Results page. This did not work in the previous PRTG versions and returned the message Your search request did not return any results (Help Documents) when you, for example, searched for the term Core Health. You could also see that your seach term was not resolved properly and displayed as core%20health.
You are now able to send a support bundle with all relevant files via Contact Support button on the Setup page when you are logged in to PRTG with a Single Sign-on user account. In the previous PRTG versions, sending a support bundle as a logged in Single Sign-on user would trigger the overload protection in PRTG and the bundle would not contain any htm files.
We fixed an issue where the returned table for a queried XML was broken when you had an object, e.g. sensor, with a tag that contained an ampersand & in it.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 24.2.95.1535
We implemented the sections for Windows Compatibility Options, SNMP Compatibility Options and Proxy Settings in the device settings in the new UI.
You can now add and edit notification triggers for objects, like probes, groups, devices, and sensors. The notification triggers are available via context menu or Actions button for the relevant object.
You can now edit the settings of a sensor via context menu in the new UI when you right click on the sensor you want to edit. Additionally you can edit the settings of a sensor in the Settings tab or via button Sensor Actions where you can perform actions like Pause Object or Scan Now. After you have saved your changes a growl message appears Settings have been saved. It may take a while for the change to apply.
You can now send GET requests to the following endpoints api/v2/groups/{id}, api/v2/sensors/{id} and api/v2/probes/{id} to receive relevant information about these objects.
We fixed an issue where the PRTG application server created a panic log file when you uninstalled PRTG. The error message then reported was Error: could not uninstall system service PRTGAppServer: service PRTGAppServer is not installed. This issue occurred when you uninstalled PRTG without having the PRTG application server installed.
