Sensors
DNS |
The DNS sensor query type Host address IPv6 (AAAA) works again. This option caused the error message “Record not found (PE112)” in some cases. We also improved IPv6 parsing in general. |
EXE/Script and EXE/Script Advanced |
The JSON result parser correctly evaluates the ShowChart and ShowTable values and sets these options as returned by your script. |
Oracle Tablespace |
The Oracle Tablespace sensor now uses the identifier you have set when adding the sensor. You can also define if you want to use SERVICE_NAME as sensor name prefix to distinguish sensors for several databases on the same server more easily. |
SNMP Printer |
On some HP printer types, adding SNMP Printer sensors could lead to null byte errors in rare cases. This should not happen again. |
SSL Certificate |
The SSL Certificate sensor can now evaluate Subject Alternative Names (SAN) additionally to the Common Name (CN). Just choose the new option Compare and show 'down' status if common name/alternative names and address/SNI do not match for the Certificate Name Validation sensor setting. |

Running sensors of this type will stop monitoring and show a down status as soon as you update to this version. Please see this article for details: The PRTG Sensor Cleanup Note: The deprecated sensor types ADO SQL, Microsoft SQL, MySQL, and Oracle SQL will continue monitoring (now using the new SQL engine in the background) and keep their configuration. Please see this article for details: Migration Path for Deprecated SQL Sensors |
Changed
Notifications
Notification Summarization |
PRTG collects up to 25 email notifications per defined gathering interval and sends the summarization as soon as this number is reached. Because of this, you may receive more than one summarization per gathering interval. The reason for this change is that some email clients have issues with long (HTML) emails. |
Improved
Sensors
HTTP Sensors |
HTTP sensors added by the auto-discovery are now named HTTP, HTTP (8080), or HTTPS depending on the connection to the target device. This helps to distinguish automatically added HTTP sensors at one look. |
Oracle Tablespace |
The Oracle Tablespace sensor includes new channels for “Database Size” (current size of the database) and “Database Size on Disk” (managed tablespace). |
SQL v2 Sensors |
You can now use placeholders in SQL query files of SQL v2 sensors (@prtg for Microsoft SQL, MySQL, PostgreSQL, :prtg for Oracle SQL, ? (question mark) for ADO SQL). Provide the input parameter in the sensor settings and PRTG will replace the placeholder in the SQL query. This is a great option if you use many SQL sensors where the queries differ in only one parameter! Furthermore, a change trigger is available for changing sensor messages of SQL v2 sensors. |
Windows Network Card |
The Windows Network Card sensor can show more data now, including 64-bit counters, virtual network interfaces, teamed adapters, and virtual connections (for example, VPN). |

System Information |
You can now view system information for all devices that PRTG monitors (when PRTG has the appropriate credentials). The devices can be either a supported Windows version or they have SNMP enabled to get information data. Open the "System Information" tab on a device overview page and see what hardware and software is installed, what processes and services run on this computer and which user accounts are logged in. Together with your day-to-day monitoring you get a really profound knowledge about your IT infrastructure by using only one source—your PRTG Network Monitor! |

SNMP Dell EqualLogic |
This version comes with three new sensor types for EqualLogic monitoring! Native support for EqualLogic monitoring has been demanded by many of our customers so we are glad that we can offer this feature to you now. You can monitor logical disks, physical disks, and the health of storage array members with three dedicated sensor types:
|
ADO SQL v2 |
The new ADO SQL v2 sensor can monitor any data source that is available via OLE DB or ODBC. It is the successor of the deprecated ADO SQL sensor. |
Windows Physical Disk I/O |
The new Windows Physical Disk I/O sensor monitors input/output operations on a disk. Important note: This sensor type supersedes the Windows Physical Disk sensor which is deprecated as of now and will be removed with the next PRTG version. Please replace the deprecated sensor with the new Windows Physical Disk I/O sensor! |
WMI Logical Disk I/O |
The new WMI Logical Disk I/O sensor monitors logical disks on a Windows device. Important note: This sensor type supersedes the WMI Logical Disk sensor which is deprecated as of now and will be removed with the next PRTG version. Please replace the deprecated sensor with the new WMI Logical Disk I/O sensor! |

Sensors
Sensor Channels |
You can now define a scaling factor (multiplication and division) for values of sensor channels with custom units. You can find this option in the respective channel settings. Note: Sensors with a scaling option in the sensor settings do not provide this option in channel settings. There are also some other sensors with custom units that do not support this feature. |
EXE/Script Advanced |
The EXE/Script Advanced sensor can now make use of a meta-scan functionality. For details please see this article: https://kb.paessler.com/en/topic/68109 |
HTTP Transaction |
HTTP Transaction sensor shows the URL of the page that provokes a warning or error status in the sensor message. |
SSL Certificate |
Newly added SSL Certificate sensors have limits for the “Days to Expiration” channel by default. This sensor type has also an improved logging (“Write result to disk”). With this option enabled certificates of the cert chain are additionally logged for better debugging possibilities, especially for the “Root Authority Trusted” channel. |
SNMP Cisco System Health |
Improved performance for the SNMP Cisco System Health sensor |
SNMP Sensors |
SNMP sensors now use paging for SNMP requests to improve their stability. |
Windows Updates Status (Powershell) |
You can define a custom port for the Windows Updates Status (Powershell) sensor. |
WMI/Windows Sensors |
All WMI/Windows sensors provide a debug option. |

Fixed
Sensors
SSH SAN System Health |
The SSH SAN System Health sensor adapts an HP firmware upgrade. After the firmware update, some sensor channels might show different data than before. Please try to add this sensor anew to get correct channel data. The corresponding error message is: The sensor encountered some problems. This might be caused by a firmware upgrade. Please try to recreate the sensor. |
SNMP Custom Advanced |
SNMP Custom Advanced and SNMP Custom Table sensors did not properly take the unit “BytesBandwidth” if you changed the configuration of this unit in a parent device or group. |
Dell PowerVault MDi Logical Disk |
Dell PowerVault MDi Logical Disk sensor now correctly recognizes disk with a minus (-) sign or an underscore (_) in the name. |
SSL Security Check |
SSL Security Check sensor prevents connection timeouts in a better way. |
SNMP Cisco System Health |
SNMP Cisco System Health sensor now shows correct memory utilization above 4 GB. |
SNMP Dell PowerEdge Physical Disk |
We fixed an issue that caused an “index out of bounds” error in some cases when adding the SNMP Dell PowerEdge Physical Disk sensor. |
NetApp cDOT sensors |
Fix for Int32 errors of NetApp cDOT sensors (support of Int64 values added). cDOT I/O and cDOT System Health sensors also perform a meta-scan when you add one of these sensor types, so you can create one sensor for one system node. This approach fixes wrong values for the "uptime" channel of the cDOT System Health sensor. Please add these sensors anew to apply the fixes. |
SCVMM sensors |
SCVMM sensors now show correct status values. |
Packet Sniffer |
Packet Sniffer sensor shows selected network adapter(s) again. |
Windows Network Card |
Windows Network Card sensor correctly shows 64 bit values. |
SNMP Printer |
Improved template handling of the SNMP Printer sensor |
SSL Certificate |
SSL Certificate sensor shows an "Unknown" status instead an error if the key length check fails. Adding the SSL Certificate sensor using a device template works correctly. |
SNMP Custom Advanced |
OIDs for the SNMP Custom Advanced sensor support can start with points (.) |
SNMP Cisco System Health |
SNMP Cisco System Health can show negative values. |
