The reset token in the link for setting a new password is now masked in the CoreWebServer.log. It was logged in a readable format before when you clicked on the link for setting a new password with the forgot password option.
Your Exchange Database DAG (PowerShell) sensor now recognizes newer versions of Exchange Server (>2019) and can distinguish between versions i.e 2010, 2013, 2016 and 2019. Previously the sensor recognized the Exchange Server 2019 version as an older version and tried to use this information, resulting in a Warning status for the Active Copy Channel with the message Could Not Read Activation Preference.
We updated our database connectors for certain EXE sensor types, e.g. Oracle SQL v2 sensor, MySQL v2 sensor and PostgreSQL sensor. Previously, the connection to the corresponding databases failed due to required encryption ciphers that did not match.
We improved the following sensor types to support the Proxy Settings in the device settings so they are able to use a HTTP proxy server when you have set up one in the device settings:
Your OPC UA Custom sensor now supports more data types, that means enums and single values from array-valued variables. Previously, the sensor supported only string, Boolean, and numeric variables.
You can now create device templates that include the sensor types Soffico Orchestra Channel Health sensor and Soffico Orchestra Scenario sensor (BETA). This enables you to add these sensors via auto-discovery.
Various other minor fixes and improvements.
We updated the Chinese, French, Japanese, Portuguese, Russian language files.
We updated the Spanish language files for certain selected sensor types.
With this PRTG version the MySQL v2 sensor does not support the integrated Windows authentication for MySQL anymore due to a license change in the database connector. The sensor will request the Windows password and username instead.
We fixed an issue for certain selected sensor types that caused the previously set scan interval to be ignored and always run for the default value of 60 seconds. In addition, the interval information was not added to the sensor log in cases where the
Public map rotation is now working again as expected. Previously, if you used the public map rotation feature without login credentials required, only the first map would be displayed or the other maps would be displayed as blank pages instead.
We implemented various improvements for the AWS v2 sensors:
We fixed an issue for certain EXE sensor types, such as the ADO SQL v2 sensor, where the parsing for arguments failed when the Connection String in the Database Specific setting contained a linebreak. The sensor reported a down status with the message Invalid Authorization Specification in these cases.
We generally hardened the approach how Microsoft Azure sensors retrieve data to avoid gaps in the sensor data.
We fixed an issue for the MySQL v2 sensor where the executed SQLV2.exe client tool reported an error with the message Parameter -sslmode is missing. With PRTG version 21.2.68.1492 we introduced a dedicated setting for the SSL mode; however, this setting was initially only implemented for the Command Line Interface. The options you could choose are the same as the values of the MySQL sslmode parameter.
We fixed an issue for certain Flow sensors, like the NetFlow v9 sensor or IPFIX sensor, that led to access violations in certain cases when the data flow contained fields with variable length.
We fixed an issue for the HPE ProLiant Memory Controller sensor that in some cases could not be created on a HPE ProLiant Gen10 server when the device type was 1 (other) in the given OIDs. An error with the message The sensor could not find any matching data on the monitored device occurred in these cases during sensor creation.
We fixed an issue for the SMTP sensors where the HELO ident that you configured in the Authentication setting of the sensor was ignored and instead e.g. the default hostname of the probe was used. This issue affected the SMTP sensor, SMTP&POP3 Round Trip sensor and the SMTP&IMAP Round Trip sensor.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 23.4.89.1500
Your SNMP Traffic v2 sensor now includes the tag snmp in the default tags that are automatically predefined in the Basic Sensor Settings when you add the sensor.
You can try out our experimental Soffico Orchestra Scenario sensor that we introduce with this PRTG version. This sensor monitors the status of processes within an Orchestra scenario. The sensor comes with the channels Aborted Count, Downtime, Finished Count, Paused Count, Running Count and Warning Count. Please note that this sensor requires a Soffico license and as of Orchestra 4.8.2.5.
We added a new parameter purpose to the /schemas/{kind} endpoint that supports the values create (for POST), update (for PATCH) or read (for a GET endpoint). The endpoint returns the appropriate schema for a given purpose.
We fixed an issue that occurred when you deleted devices that were included in a map. Previously after you deleted devices in the new UI that were included in a publicly accessible map you would receive the warning message Monitoring might be incomplete or inaccurate due to fundamental problems in your PRTG installation! Click here for more information! when you opened the map then in the classic UI.
In addition, the Core Health sensor displayed a down status with the error message Free Physical memory is below error limit of x in Free Physical Memory. The public access page for the map was also not accessible and reported the error Map Refresh Failed in these cases.
PRTG shows the error dialog Error (Bad Request) in the web interface again when you attempt to save invalid changes to settings. Previously, the error description was not displayed. The page reloaded without any indication when you tried to save your changes with invalid settings. The error was only logged in CoreWebServer.log.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 23.3.88.1385
The CPU usage of the PRTG application server is on normal level again. In the previous PRTG 23.3.88 preview versions, it caused unnecessary high CPU load on the server.
We updated the German and Spanish language files.
We hardened the mechanism for the automatic update of remote probes in PRTG with this PRTG version. Previously, sometimes remote probes required a manual update after you auto-updated your PRTG server with a new version due to a connection issue. Please note that this change will take effect when you update from PRTG 23.3.88 to the following version, not immediately after updating to this PRTG version.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 23.3.88.1359
Your AWS EC2 and AWS RDS v2 sensors will show a warning message if the limit of the channel CPU Credit Balance limit has less than 1 credit available. Previously the sensors were showing an error status. Please note that this change applies only when you add this sensor type as new sensor.
We added two new options in the MQTT Specific settings of the MQTT Subscribe Custom sensor for a better message handling. The option Add duration since last message will set a threshold alarm that will notify you when no message was received. Previously, the sensor went into unknown status before when no message was received in the scan interval. This default behavior will remain if the setting for Add duration since last message is not enabled. The option Retain last sensor value keeps the last message on the live charts and allows you to monitor specific JSON values of the payload.
Your SNMP Buffalo TS System Health sensor is now able to display an additional status for the channel Firmware Update Available. Previously, the status was not included in the lookup file and therefore displayed an error with the message undefined lookup value (3) when the value 3 was sent to the sensor. The value 3 in this case represents the status latest.
Various other minor fixes and improvements.
We updated the Spanish and German language files for certain selected sensor types.
We fixed an issue that caused the Failover node to become unreachable when you added a new contact to the Notification Contacts settings of the Master node.
We fixed an issue where dependent objects, like sensors and devices, were not paused if the configured master sensor went into error status due to exceeded limits. When you configured the sensor under Dependency Type as Master sensor for parent then the issue occurred in rare cases when the sensor was not saved to the device tree while the limit status changed. The issue only affected newly created sensors.
You can now create libraries again when you are logged in as a user with read/write access. This did not work before in the previous PRTG version 23.3.86.1520 when you were logged in as a read/write user that has full access in the according user group. You would get an Unauthorized ajax error message for adding a new library before.
We fixed an issue where in certain cases the probe service stopped working and caused the probe to disconnect from the PRTG core server. The probe service then reported a high CPU usage in these cases and sometimes access violations were logged in the PRTG probe.log additionally. The issue was probably caused by the DNS v1 sensor that we declared as deprecated with PRTG version 21.3.69.1333 and which was replaced with its successor DNS v2 sensor. For more information about deprecated sensor types and their alternatives please see our Knowledge Base article: https://kb.paessler.com/en/topic/89505.
We fixed an issue in the Monitoring settings for the Scanning Intervals section. You can now enter multiple scanning intervals again with the format of Coordinated Universal Time (UTC) points, like @ UTC hh:mm , hh:mm. Previously intervals with the "@ UTC" format were treated as duplicates and the entries could not be saved. Please note that you have to enter different time periods in the scanning intervals when you add multiple intervals in the UTC format.
Note:The input validation still incorrectly fails when you add a UTC at a full hour that is already set as hourly scanning interval. For example, @ UTC 06:00 fails to save when there is already a scanning interval with 6h while @ UTC 06:01 would work in this case.
We fixed an issue for certain sensor types that ran into the error no available in the Specific settings of the sensor during sensor creation. The issue happened when a timeout value higher than 300 was set in the registry for the initial sensor scan when you added the sensor. Sensor types affected were Microsoft 365 Service Status Advanced, Veeam Backup Job Status Advanced sensor, for example.
The Beckhoff IPC System Health sensor now supports IPv6 as IP Version connection that you can configure in the Basic Device Settings under IP version of the monitored device. The sensor appeared under Sensor types that are not IPv6 compatible in the previous PRTG versions due to a missing compatibility flag in the sensor library.
We fixed an issue for custom sensor types, like the HTTP Push Data Advanced sensor, where channels were created as duplicate when there was a trailing whitespace behind the relevant channel name. The issue occurred after a PRTG core server restart. The whitespace was removed and since it did not match the previous channel name, the sensor would create a duplicate.
We fixed the handling of HTTP methods that are returned after a redirect to follow the Post/Redirect/Get (PRG) pattern. This prevents the contents of the original POST to be resubmitted by redirecting the client to another location. If you select the Request Method POST, for example, under the HTTP Specific settings of the sensor, then the first request will use this method. If a request is redirected, all further requests will use GET. Redirects of requests that use GET and HEAD will continue to use GET and HEAD, respectively. This change affects all HTTP based sensor types, like the HTTP sensor and HTTP Advanced sensor.
Your Microsoft Azure sensors now query data in a slightly longer time span to make sure data is returned from Microsoft Azure and that every time stamp is considered. Previously, it could happen that Azure did not return any value when the queried time span was too close to the present as it would query only the most recent one and not also the latest data.
Note: The Microsoft Azure SQL Database sensor will throw an exception in case no result is returned from timeseries. Microsoft Azure Storage Account and Microsoft Azure Virtual Machine sensors return default value = 0 in case no result is returned from timeseries.
We fixed an issue for the NetApp I/O v2 sensor that occurred with the ONTAP version update to 9.12.1P3. Due to changes in the API, the sensor received additional unexpected information which resulted in an error with the message The queried field "value" is empty for NetApp Cluster systems.
We fixed an issue for OPC UA sensors that could run into a memory leak on the probe system causing the probe service to stop. The issue occurred only in certain cases when you ran a large number of OPC UA sensors, like OPC UA Certificate sensor, OPC UA custom sensor and OPC UA Server Status sensor with a short scan interval.
We fixed an issue for the Redfish System Health sensor that in certain cases reported an error when the monitored device did not sent a Thermal service. The sensor ran into an exception and reported the error message No 'Thermal' service found in Redfish chassis. The channel for Thermal Status will now report the status Offline/Absent when there is no Thermal data sent by the monitored device. The channel for Thermal Status will not be created if the target system does not support this service determined with the first scan.
We fixed an issue for the SNMP Cisco System Health sensor that resulted in sensor logs that were written into the \Logs\sensors folder when you have selected the option Discard result in the Debug options of the sensor. The sensor kept overwriting the log files in this case when the store result option was disabled. Additionally, the sensor disabled the option Store result automatically after writing log files and reset it to Discard result. We also fixed this behavior so that you can now edit the options again manually.
We fixed an issue for the SNMP Custom String sensor where the parameter for the setting Interpret Result As was always set to the String (default) option, regardless of the option you set before. This issue occurred when the sensor was used in a device template.
Your SNMP Nutanix Hypervisor sensor will display the speed in the column Last Value (speed) for Bytes Received when you update to this PRTG version. In the previous PRTG versions, the Last Value (speed) for Bytes Received was missing and had the unit Megabyte instead of Mbits configured.
We have fixed an issue that prevented a sensor from being cloned to more than one device. The same issue would also occur if you tried to clone another sensor to another device after the first clone attempt. In both cases you would receive an error message stating Invalid operation. You can now clone a sensor (or different sensors) to more than one device.
We fixed an issue that prevented you from saving new or edit existing comments in the Comment tab of a device or a sensor.
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 23.3.88.1319
We improved the handling of HTTP requests for the HTTP v2 (BETA) sensor to follow the Post/Redirect/Get (PRG) pattern.
We fixed an issue for the channel setting Custom Unit in the REST Custom v2 sensor that was displayed even if you selected a different unit than custom. The field will now be displayed only when you have selected Custom (default) for the relevant channel as unit before.
We fixed an issue that resulted in a missing cloned group in the new UI tree when you have cloned the group before in the classic UI and removed one device from the cloned group afterwards. Instead of only missing the deleted device in the new UI the whole group was gone in these cases.
We improved the navigation behavior of cards on the device and sensor overview pages.
Your API Keys are no longer logged in a readable format in the CoreWebServer.log when you have created an API key and executed an API call request with it. The issue only occurred for the Log in Debug Level.
You can now filter emails that match a defined regular expression. The new filter filters email whose Subject, From or Body fields match the defined regular expression. You can set the new option under the Microsoft 365 Settings.
Important: The regular expressions filter will result in the Down status if there are more than 10,000 emails in the mailbox folder you want to monitor. This is because the regular expression filter is applied after the emails are retrieved from the API. The larger the volume of emails, the greater the impact on performance. Enable the Filter by Age setting or use a non-regular expression filter in addition to the regular expression filter to reduce the number of emails.
Various other minor fixes and improvements.
We updated the Dutch language files for certain selected sensor types.
We fixed an issue that prevented notification templates from being edited within the notification trigger tab.
You can now enter a folder path with a folder that contains ANSI-characters, like umlauts or accents, in the PRTG Core Server Tab of the PRTG Administration Tool. Please note that this change does not work for unicode characters, like the Cyrillic language. If you select a folder path that contains non-ANSI characters or if you enter a folder path name with such in the field for Local Storage of Data Files and Monitoring Database, then an according error message will be displayed.
During PRTG installation, when the license server is unreachable due to connection or license expiration issues, the following error message will be displayed: Either the license server is not available because you are offline, or you cannot use the current version of installer because your license has expired. Please check your connection or log into the Paessler shop, make sure your maintenance contract is active and restart the installer. Previously, the installation displayed an error with the message that the license is invalid or that maintenance has expired.
We fixed an issue where in rare cases the execution of the button Test Single Sign-On Authorization Endpoint led to an access violation. This issue occurred only in very rare cases if your Application (Client) ID for loading the configuration contained a blank space at the end.
We fixed an issue for user groups that had the setting Allow user group members to create certain sensors only enabled. When you created a user group with the mentioned setting and did not select any sensor types in the list, then all the sensor types would be selected after a PRTG core server restart for this user group.
We fixed an issue for the HL7 sensor in the settings for Message Header where the Default message header was overwritten in certain cases. The issue happened when you entered data for the setting Override message header but you activated the radio button for Default message header afterwards. In those cases, the sensor always took the override parameters instead of the selected default headers from the script.
Your HTTP Push Data sensors will show again their values in the Last Value column of the channel list of the sensor as well as in the channel gauges of the sensor Overview tab. The Last Value column did not display any data before in the previous PRTG versions for the HTTP Push Data sensor, HTTP Push Data Advanced sensor and HTTP IoT Push Data Advanced sensor.
Your SNMP Disk Free and SNMP Memory sensors now display valid values for monitored disks with a larger size >16 terabyte and memory storage >2 terabyte again. In the previous PRTG versions, these sensor types displayed random values or reported an error code 2003.
We fixed an issue for the SSL Security Check sensor and SSL Certificate sensor that did not work anymore when a SOCKS proxy server for sensor connection was used in the previous PRTG versions. The sensors reported an error with the message The connection has dropped (PE039) in these cases.
We fixed an issue where the transfer of your probes to another server may have failed in certain cases and resulted in a deadlock with the previous PRTG versions. With PRTG version 23.2.84.1566 we announced that you can find the Probe Transfer feature for PRTG Desktop under Probe Connection Settings in the PRTG setup and that it is no longer available in the Experimental Features section.
The application server may be down in certain cases when you update to this PRTG preview version 23.3.87.1579. You can see this with the Application Server Health (Autonomous) sensor that shows a down status. As a workaround, please restart your PRTG core server to make the application server go up again. We will deliver a fix for this issue in the upcoming PRTG versions.
Solved with Preview PRTG 23.3.88.1319
You can verify the authenticity of the PRTG installer with the Secure Hash Algorithms for the following versions and release channels:
Preview 23.3.87.1579
We fixed an issue where it was not possible to pause a device via API with /api/v2/devices/40/pause.
You can now create, read, update and delete API-Keys with HTTP requests via PRTG API v2. For example, a POST request to users/{id}/api-key will create an API key with name, description and access level properties for the user. For more information about how to use HTTP requests in the PRTG API v2 concerning API keys please see our updated Knowledge Base article: https://kb.paessler.com/en/topic/90008.
We improved the handling for JSON-path expressions in the REST Custom v2 sensor that in some cases could not be mapped if there were boolean strings with true and false. The mapping now works for counter and integer Value Type in the Channel Settings of the sensor with a given JSONPath/XPath.
You can try out the experimental SNMP Traffic v2 sensor. The SNMP Traffic v2 sensor monitors bandwidth and traffic on a device via the Simple Network Management Protocol (SNMP). This sensor type has the same basic settings as its predecessor and comes with the additional channels Broadcasts In (number of incoming broadcast packets), Broadcasts Out (number of outgoing broadcast packets), Multicasts In (number of incoming multicast packets), and Multicasts Out (number of outgoing multicast packets). This sensor is not affected by the following SNMP compatibility options set in the parent device: Port Name Template, Port Name Update, Port Identification, Start Interface Index, and End Interface Index.
