New

Sensors


Dell EMC Unity Enclosure Health v2

The new Dell EMC Unity Enclosure Health v2 BETA sensor monitors the health of a disk-array enclosure (DAE) or a physical or virtual disk processor enclosure (DPE) on a Dell EMC storage system. It shows the health status and, depending on the target device, temperatures as well as the status of cooling modules, drives, storage processors, power supplies, and link control cards. This sensor will help you to ensure your Dell EMC Unity enclosure is always working as expected.

Microsoft Azure Subscription Cost

The new Microsoft Azure Subscription Cost BETA sensor monitors the cost in a Microsoft Azure subscription so that you can keep track of the overall expenses of your subscription. It shows the current and previous period cost, the cost forecast, user budgets, and the most expensive service by category.

Veeam Backup Job Status

The new Veeam Backup Job Status BETA sensor monitors the status of all backup job runs on the Veeam Backup Enterprise Manager in the last 24 hours. It shows the number of successful and failed job runs, running and finished job runs, job runs in warning states, and scheduled backup jobs. This sensor gives you a general overview of the status of your backup jobs so that you see the jobs which need your immediate attention at a glance.

Improved

Sensors


Modbus TCP Custom

Thanks to your feedback, we implemented several improvements for the Modbus TCP Custom BETA sensor that we introduced in the last PRTG version.
  • We improved the usage of the sensor settings.
  • We increased the range for register addresses.
  • Register numbers can now start from 0.
  • You can define a lower scanning interval than 60 seconds.
  • The sensor log provides more information.
  • We updated help texts and documentation.
Important: After updating from PRTG 20.4.63 to 20.4.64 or later, you will have to add the sensor anew. Running Modbus TCP Custom sensors will show a down status after you have installed the update due to changes in our underlying Modbus monitoring configuration.

MQTT sensors

You can now create device templates that include the sensor types MQTT Round Trip, MQTT Statistics, and MQTT Subscribe Custom. You can use the device templates to add MQTT sensors via auto-discovery.

MySQL v2

The MySQL v2 sensor now supports authentication with caching_sha2_password on MySQL 8.0 and later. In previous versions, the sensor showed the error message Authentication method 'caching_sha2_password' not supported by any of the available plugin when you tried to monitor MySQL server version 8.0.

OPC UA Server Status

We further improved the OPC UA Server Status BETA sensor that we introduced in the last PRTG version. Thank you for your feedback!
  • The sensor can now monitor session related metrics if diagnostics data is activated on the server, so that PRTG can notify you if there are too many ongoing sessions or the amount of timeout sessions increases.
  • We added support for authentication with username and password, as well as you can use encryption and provide a certificate to authenticate the sensor against the OPC UA server.
  • We improved the general performance of OPC UA sensors in this version by minimizing their network communication.
  • We drastically reduced the amount of log entries that OPC UA sensors write into the probe.log file.

SSL Certificate

The SSL Certificate sensor has a new timeout setting for TCP read requests, which is useful if you monitor a slow server with the sensor.

Fixed

Sensors


Cisco IP SLA

Tag and Owner are now in the correct column when adding the Cisco IP SLA sensor. Furthermore, the sensor will not erroneously add a vendors_cisco tag to a device anymore when you run an auto-discovery and the discovered device is not a Cisco device.

Google Analytics

You can add Google Analytics sensors again. The sensor type needed a new OAuth verification by Google to be able to access data.

HTTP Push Data sensor

The HTTP Push Data Advanced sensor now applies the unit to a channel value if provided in the push message and as defined in the Channel Unit Configuration settings.

HTTP Transaction

Smart URL Replacement in the HTTP Transaction sensor now even works if you use the Alternate/Compatibility Mode as Monitoring Engine. In previous versions, the URL replacement only worked with the recommended default monitoring engine. Please note that support for ports in smart URL replacement when using the compatibility mode will only come with a later version.

SNMP Custom Table

We fixed an issue with SNMP Custom Table sensors that are created via auto-discovery. In certain cases, the sensors were created with invalid IDs and uncommon sensor names and immediately showed a down status after creation.

SQL v2 sensors

We fixed an issue with SQL v2 sensors that caused a down status with the message Error: An item with the same key has already been added because PRTG did not properly reset the parameters after a sensor timeout.

WMI sensors

The auto-discovery with template can add certain WMI sensors again. In previous versions, you could not add the sensor types WMI Exchange Server, WMI Sharepoint Process, and WMI Vital System Data v2 sensors, for example, by using an auto-discovery with template.

Fixed

Server


Active Directory

If you change the Login Name of an Active Directory user account in PRTG, it is not possible anymore to login with the changed login name because this user account does not exist in the Active Directory. The login with the original login name still works and will create a new Active Directory user account in PRTG. In previous version, the behavior in such cases was unreliable.

API

We fixed an issue with historic data queries via the PRTG API. In certain scenarios, the queries could take too much time since we improved the memory consumption of historic data queries in PRTG 20.1.57.

Config

We fixed a potential deadlock that could happen when PRTG saved the configuration, resulting in a server crash in rare cases.

Languages

The Local Probe now keeps its name after a server restart in Japanese, Russian, and Chinese language versions. In previous versions, the name of the probe was overridden by question marks (??) after a restart.

Login

We fixed an issue with the login of PRTG user accounts that occurred in rare cases when changing the password of a user who was logged in into PRTG Desktop at the same time. A re-login was not possible for some time in such cases.

Maps

We fixed a potential deadlock that could happen in rare cases when using the Map Designer. PRTG became unresponsive in such cases and required a server restart to work again.

Multi-Edit

  • You can edit the settings of multiple devices, groups, and probes at once again. In previous versions, multi-edit on these objects resulted in an error with the message The validation of the data you entered has failed when you saved your changes.
  • Multi-editing limits of sensors now properly works for sensors with channels that display data in percent of the maximum value. In previous versions, the applied limit values were incorrect if two or more multi-edited channels had different maximum values.

Notification Templates

We removed some redundant entries from the History tab of notification templates that still appeared on 64-bit installations of PRTG.

Reports

Links to sensors and devices in PDF reports work again. In previous versions, the links included a wrong port and could not be opened.

Uninstall

We fixed an issue that prevented a clean uninstall of PRTG on Windows 10 Pro 64-bit instances.

Fixed

WebGUI


Libraries

You can collapse and expand library nodes again.

Fixed

System Information


Data

The System table on System Information tabs shows data for specific SNMP devices again. In previous versions, PRTG could not retrieve system information data from SNMP devices if an interface had multiple IP addresses. You received the message Error: duplicates not allowed in this case.

Fixed

PRTG for Android


Sorting

Sorting by status in the alarms section of PRTG for Android corresponds to the sorting in the web interface again if you connect your app to PRTG version 20.4.64 and later.

Note

Sensors


Beta Sensors

The following sensor types are not in beta status anymore and are now fully supported.
  • AWS Cost
  • Cloud HTTP v2
  • Cloud Ping v2
  • DNS v2
  • Microsoft 365 Service Status
  • Microsoft 365 Service Status Advanced
  • MQTT Round Trip
  • MQTT Statistics
  • SNMP Nutanix Cluster Health
  • SNMP Nutanix Hypervisor
  • SNMP Fujitsu System Health v2
  • WMI Microsoft SQL Server 2019
  • Zoom Service Status

Experimental Sensors

We added two new experimental sensors that you can manually enable.
  • Microsoft Azure SQL Database: The experimental Microsoft Azure SQL Database sensor monitors your Microsoft Azure SQL Database instances so that you are notified if there is an issue with your SQL instance. The sensor in the current experimental status has the known issue that the sensor will stop working as expected it if the database type changes or has changed from vCore to DTU or vice-versa. If you try out the sensor and encounter this issue, we would kindly ask you to contact us and provide the sensor logs if possible. This will help us to further develop the sensor.
  • Modbus RTU Custom: The experimental Modbus RTU Custom sensor monitors up to 5 values that your Modbus RTU device returns.

Note

Known Issue


Remote Probes

Some customers reported connection issues of remote probes after the update to PRTG 20.4.64.1402. We found out that special characters in the name of a remote probe can prevent the probe from receiving the update and from connecting to the PRTG server. Characters that may cause this issue are, for example, German umlauts (ä, ö, ü) or Japanese language characters.

Workaround: To reconnect an affected remote probe in such a case, manually update the remote probe (download the remote probe installer from the web interface and run it on the remote probe system), or open the PRTG Administration Tool on the remote probe system and remove special characters from the name of the probe under probe settings until we can provide a fix.

Fixed

Libraries


Library Filters

Filters in libraries properly work again. In the previous PRTG version 20.4.63.1412, filtering on a Linked Object did not work. A library node always showed all sensors of a PRTG instance that matched the filter, not only matching sensors of the linked object. Furthermore, Filter by Tags had issues with correct filtering so that the library node showed wrong or no sensors in some scenarios.

calendar

October 20th 2020 – Version 20.4.63.1412


New

Sensors


Dell EMC Unity VMware Datastore v2

The new Dell EMC Unity VMware Datastore v2 BETA sensor monitors a VMware datastore on your Dell EMC Unity storage system. With this sensor type, you can keep track of the free size of a VMware datastore on your Dell EMC storage, as well as you will always see the number of hosts, virtual machines, and virtual drives at a glance.

Microsoft Azure Virtual Machine

The new Microsoft Azure Virtual Machine BETA sensor monitors the status of a virtual machine in a Microsoft Azure subscription. Additionally to the overall status of a virtual machine, you can also monitor CPU usage as well as used and remaining CPU credits with this sensor. This will help you to act before your credits run out and the virtual machine stops.

Modbus TCP Custom

The new Modbus TCP Custom BETA sensor monitors values that your Modbus TCP server returns. With this new sensor type, you can keep an eye on your environment equipment like cooling units, power supply, backup generators, and temperature. This helps you to ensure your infrastructure always runs at its best.

OPC UA Server Status

The new OPC UA Server Status BETA sensor monitors status, uptime, and diagnostic information of your OPC UA server. With this new sensor type you can ensure your devices are available using OPC UA and your production processes run flawlessly.

In this version, you can also try out an experimental OPC UA Custom sensor that you can manually enable. The sensor monitors multiple nodes of OPC UA servers and returns the contained values.

Soffico Orchestra Channel Health

The new Soffico Orchestra Channel Health BETA sensor monitors the availability of the Soffico Orchestra API and shows the status and overall number of successful and failed channel calls.

Improved

Sensors


Cloud HTTP v2

The Cloud HTTP v2 BETA sensor now supports Smart URL Replacement like other HTTP sensors. With this functionality, you can easier define custom URLs that you want to monitor with this sensor type.

Exchange (PowerShell) sensors

You can now monitor Exchange Server 2019 with all Exchange (PowerShell) sensors. The sensor types support all Exchange server versions as of 2010.
  • Exchange Backup (PowerShell)
  • Exchange Database DAG (PowerShell)
  • Exchange Database (PowerShell)
  • Exchange Mailbox (PowerShell)
  • Exchange Mail Queue (PowerShell)
  • Exchange Public Folder (PowerShell)

SNMP Cisco ASA VPN Connections

We improved the error handling of the SNMP Cisco ASA VPN Connections sensor. In cases where the requested OID of a channel is missing on the target device, the OID is now shown in the sensor message with according information and the sensor keeps its status. In previous versions, the sensor showed a down status with the error message "No such object" (SNMP error # 222) in such cases even if other channels were able to retrieve data.

SNMP Cisco ASA VPN Traffic

We added the option to monitor VPN connections that work with IKEv2 tunnels to the SNMP Cisco ASA VPN Traffic sensor. You can choose the new IKEv1 and IKEv2 option in the IKE Version Handling section of the sensor settings in this case.

Note: This option is in beta status and might not work properly in every case, so we would love to hear your feedback about it. Please send it to [email protected].

Changed

Sensors


Microsoft 365 Service Status

Degraded services in the Microsoft 365 Service Status BETA sensor now result in a warning status instead of down by default. This change also corresponds to the status definition of degraded services in the Microsoft 365 Service Status Advanced BETA sensor, where degraded services were always defined as warning status.

Improved

Notifications


Notification Templates

We improved the content of the History tab for notification templates. The history of a notification template now only shows one entry per creation or modification and only the settings that were actually changed. The entries have a clearer wording aligned to other places in the web interface and referenced objects are written with both their name and ID. This will help you with tracking the creation and changes of a specific notification template.

Notification Triggers

You can now define if you want to inherit notification triggers from parent objects for new sensor types. Several sensor types that we added over the last few PRTG versions were missing the inherit option on their Notification Triggers tab and showed the message (Property not found) instead.

Improved

Server


Libraries

We slightly improved the performance of libraries by changing the approach of how libraries are calculated to event-based instead of doing regular polling. You will especially benefit from this improvement if you have libraries with a high amount of sensors.

Fixed

Sensors


Sensor Messages

Sensors now keep their messages even if you change a channel setting like limits or spike filter that causes a recalculation. In older PRTG versions, the current sensor message disappeared after such a change.

Sensor Statistics

Sensors now show a calculated value for uptime, downtime, and coverage in the general information section on a sensor's overview tab even if they never left the down status but receive values. This can be the case if limits are breached or lookup values cause the down status directly upon sensor creation. In older PRTG versions, sensors showed N/A for uptime, downtime, and coverage in such cases.

Fixed

Server


API

We fixed an inconsistency that appeared in the results of the column groupnum in getobjectstatus.htm API calls in certain cases. Depending on your device tree structure, the call sometimes returned incorrect values for the number of groups.

As of this version, groupnum always returns the correct number of subgroups if you perform the call for a specific group, and the number of all groups plus one for root if you perform the call for root (id=0) just as shown on the system status page.

Fixed

WebGUI


System Information

The column headers of tables on System Information pages are correctly displayed again.

Various


Language Files

We updated the German and Japanese language files.

All parts of PRTG

Various other minor fixes and improvements, updated user manual

Changed

Tree version


Tree version update

The configuration file of this version is not downwards compatible with previous PRTG versions.

Note

Known Issue


Libraries

We detected an issue with libraries in PRTG version 20.4.63.1412. Filtering on a Linked Object does not work. A library node will always show all sensors of a PRTG instance that match the filter, not only matching sensors of the linked object. Furthermore, Filter by Tags does not properly work.

If you actively use filtered libraries, especially in combination with notification triggers, we strongly recommend that you do not install PRTG 20.4.63.1412.

Status: Resolved with PRTG version 20.4.63.1427.

calendar

September 15th 2020 – Version 20.3.62.1397


New

Sensors


Cloud HTTP v2

The new Cloud HTTP v2 BETA sensor monitors a web server and shows the loading times from different locations. It is the successor of the Cloud HTTP sensor introduced with PRTG 14.x.14 that we will deprecate and remove from PRTG in an upcoming version depending on your feedback for the new Cloud HTTP v2 sensor.

The new sensor uses a new technology in the backend and comes with an enhanced feature set. For example, you can now individually define the regions that you want to use for the requests.

Cloud Ping v2

The new Cloud Ping v2 BETA sensor monitors the ping times to a device from different locations. It is the successor of the Cloud Ping sensor introduced with PRTG 14.x.14 that we will deprecate and remove from PRTG in an upcoming version depending on your feedback for the new Cloud Ping v2 sensor.

The new sensor uses a new technology in the backend and comes with an enhanced feature set. For example, you can now individually define the regions that you want to use for the requests.

Dell EMC Unity File System v2

The new Dell EMC Unity File System v2 BETA sensor monitors a file system on a Dell EMC Unity storage system. It shows free size, allocated size, as well as size and number of snapshots.

This new Dell EMC Unity storage sensor supports Unity OE API version 5 and later, which the existing REST Dell EMC File System BETA sensor is not capable of.

Dell EMC Unity Storage Capacity v2

The new Dell EMC Unity Storage Capacity v2 BETA sensor monitors a Dell EMC storage system and shows free size, used size, preallocated size, and subscribed size.

This new Dell EMC Unity storage sensor supports Unity OE API version 5 and later, which the existing REST Dell EMC Capacity BETA sensor is not capable of.

Dell EMC Unity Storage Pool v2

The new Dell EMC Unity Storage Pool v2 BETA sensor monitors a storage pool on a Dell EMC Unity storage system. It shows the health status of the storage pool, as wells as several size metrics.

This new Dell EMC Unity storage sensor supports Unity OE API version 5 and later, which the existing REST Dell EMC Pool BETA sensor is not capable of.

WMI Microsoft SQL Server 2019

You can now monitor your Microsoft SQL Server 2019 with PRTG! The new WMI Microsoft SQL Server 2019 BETA sensor monitors your database performance and shows values from SQL General Statistics, Access Methods, the Buffer Manager, the Memory Manager, the Locks Manager, and SQL Statistics.

New

Notifications


MQTT Messages

You can now connect PRTG to your MQTT broker and send (publish) messages with placeholders about alerts to a custom topic. Your MQTT infrastructure can then process the messages further.

Together with the three MQTT sensor types that we already released in previous versions, PRTG as an all-inclusive solution will help you to easier operate your MQTT infrastructure, day by day.

Improved

Server


Cluster

We improved the scope of read- and write-locks in PRTG cluster installations. This leads to a slightly better overall cluster performance in certain monitoring configurations.

Improved

WebGUI


Context menus

Context menus in the device tree now better reflect the actual access rights of a PRTG user account. Users with restricted permissions to an object (for example, users with read access to the object) can only click the menu items if they are allowed to perform the corresponding action.

Changed

API


Access rights

Querying access rights via the API as treejson now returns
  • 0 for no rights
  • 100 for read rights
  • 200 for read/write rights
In previous versions this was 0 for no rights and 1 for read/write rights. The change was necessary to improve the context menus regarding access rights (see above).

Types

API calls return type_raw without index again. For example, you will now receive device if you perform an according API call instead of device[1] as it was the case in previous versions.

Fixed

Sensors


Google Drive

You can add Google Drive sensors again. The sensor type needed a new OAuth verification by Google to be able to access data. Please note that the Google Analytics sensor is still in the re-verification process and still cannot be created.

SNMP Cisco CBQoS

The SNMP Cisco CBQoS sensor now supports the types tunnel(8) and wirelessInterface(9). In previous versions, created sensors of this type had incorrect names if tunnel or wireless interface were returned by the target device.

VMware Host Hardware Status (SOAP)

The VMware Host Hardware Status (SOAP) sensor now shows an appropriate warning message and instructions if no hardwareStatusInfo is available on the target device. In previous versions, the sensor showed no message in this case.

Zoom Service Status

The Zoom Service Status BETA sensor now supports the status Under Maintenance in all channels. We defined it as Warning status because the monitored Zoom service does not work as expected when it is under maintenance. The new status is necessary to reflect a change in the Zoom API, which recently resulted in an undefined lookup error in the Meeting Telephony Services channel.

Fixed

Server


Cluster

  • We improved the stability of PRTG cluster updates. In certain cases, it was not possible to update failover nodes due to a failing license check. PRTG showed a License invalid error message in such cases.
  • We fixed an issue with cluster installations where failover nodes could not properly load language and lookup files on startup when certain sensor types were running on the instance. The failover node did not work anymore in this case. The issue was caused by some of the new sensor types we introduced over the last couple of PRTG versions, for example, DNS v2, AWS Cost, and MQTT sensors.

Geo Maps

We fixed an issue with the automatic resolution of geo locations when adding a new remote probe. Windows systems with a language setting that does not use a point as decimal separator (for example, comma in German) resulted in an invalid format of the coordinates.

Improved

Various


Languages

We updated the German and Dutch language files, as well as we improved translations for Spanish, French, Russian, and Simplified Chinese in several places.

The new Dell EMC Unity Storage LUN v2 BETA sensor monitors a LUN on a Dell EMC Unity storage system. It shows the health status of the LUN, as well as several size metrics.

This new Dell EMC storage sensor also supports Unity REST API version 5 and later, which the existing REST Dell EMC LUN BETA sensor is not capable of.

Microsoft 365 Service Status

The new Microsoft 365 Service Status BETA sensor monitors the overall status of all services of a Microsoft 365 subscription. It shows the total number of operational services, degraded services, interrupted services, and services in warning status.

With the help of this sensor type, you will always see the status of your Microsoft 365 services at a glance and can immediately step in before the workflow of your entire company is affected if there is an issue.

See also the Knowledge Base articles How and where do I obtain credentials for Azure AD? and How do I set permissions for the Office 365 Management APIs? for more information on how to add the sensor.

Microsoft 365 Service Status Advanced

The new Microsoft 365 Service Status Advanced BETA sensor monitors the detailed status of all services of a Microsoft 365 subscription. With this sensor, you get a detailed status of all Microsoft 365 applications and products you are subscribed to like, for example, Microsoft Teams, Exchange Online, Skype for Business, OneDrive for Business, or Planner.

You can individually define in the Add Sensor dialog which Microsoft 365 services you want to monitor and create a sensor for.

See also the Knowledge Base articles How and where do I obtain credentials for Azure AD? and How do I set permissions for the Office 365 Management APIs? for more information on how to add the sensor.

MQTT Subscribe Custom

The new MQTT Subscribe Custom BETA sensor subscribes to an MQTT topic and monitors the returned values. It can show up to five numerical values from the received JSON data.

Together with the MQTT Round Trip BETA and MQTT Statistics BETA sensors that we released in previous versions, you are now perfectly equipped for MQTT monitoring with PRTG.

Zoom Service Status

The new Zoom Service Status BETA sensor monitors the global status of each Zoom service. It shows the operational states of the services and according error messages if something went wrong.

This new sensor type will help you to always know about the availability of Zoom to be able to immediately react if there is an issue, which is especially important if your company relies on remote work via Zoom.

Changed

Sensors


EXE/Script and EXE/Script Advanced

The EXE/Script sensor and the EXE/Script Advanced sensor now require PowerShell 3.0 on the probe and target system, as well as .NET 4.7.2 on the probe system.

MQTT Round Trip and MQTT Statistics

While implementing the new MQTT Subscribe Custom sensor, we also moved the Port setting for the connection to the MQTT broker from the sensor settings to the Credentials for MQTT settings on device, group, and probe level. This affects the existing MQTT Round Trip BETA and MQTT Statistics BETA sensors. Running instances of these sensor types will show a down status with error code PE270 after you have updated to PRTG 20.3.61.

If you use the default port 1883 for MQTT connections, please manually re-scan your MQTT sensors to bring them up again. If you use another port for MQTT connections, please change the port in the Credentials for MQTT settings of the MQTT sensors' parent device (or on group or probe level if you inherit the settings) and re-scan the sensors.

Improved

Sensors


Core Health

The Core Health sensor shows more information about the health of the PRTG core server. It now monitors the number of Notifications in Send Queue, the Number of State Objects, and the number of Probe Messages per Second in 3 new channels. The additional information will help us to better help you if you encounter issues with your PRTG installation.

DNS v2

The DNS v2 BETA sensor now fully supports devices with FQDN or host names. In previous versions, the sensor occasionally was only able to monitor devices that have an IP address defined in the settings.

MQTT sensors

  • We introduced connection sharing for MQTT sensors. The sensors now open only one connection per broker URL, so in general less clients will be connected to the broker.
  • We improved the error handling of MQTT sensors. For example, the MQTT Round Trip v2 BETA sensor now shows a down status if there are wrong or missing entries in the Client Authentication settings.

Improved

Server


Auto-Discovery

You can now see in the device tree if an auto-discovery for a device is in queue. In this case, the device will show the message Auto-Discovery pending, for example, when there already run auto-discoveries on 10 devices at the same time.

Notification Delivery

You can now also test the configuration of your fallback SMTP relay server in the Notification Delivery settings. PRTG will try to send a test e-mail to both SMTP relay servers if you click Test SMTP Settings and adds an according entry to Logs | System Events | Notification Related.

Fixed

Sensors


NetApp Volume

The NetApp Volume BETA sensor can now handle big return values. In previous versions, the sensor showed a down status because a conversion error if, for example, there were snapshots older than a few years on the volume.

SSH Meminfo

  • The SSH Meminfo sensor is now DASH compatible and can monitor Ubuntu devices again.
  • The SSH Meminfo sensor can now also monitor target systems where /proc/zoneinfo information is not available.

Fixed

Server


Pause

Sensors now resume monitoring after your defined timespan elapsed even if you paused them indefinitely first. In previous versions, the sensors indefinitely kept the paused by user status in such cases.

Reports

We fixed an issue where in rare cases historic data reports for Sensor Factory sensors still did not contain values if you selected No Interval (Display Raw Data) as Average Interval after the initial fix in the last PRTG version.

Time zones

Time zones that you individually define for reports or other PRTG user accounts are saved and correctly applied again.
