PRTG Manual: Windows Updates Status (PowerShell) Sensor
<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Windows Updates Status (PowerShell) Sensor
The Windows Updates Status (PowerShell) sensor monitors the status of Windows updates on a computer and counts the available and installed Windows updates that are either from Microsoft or from the local Windows Server Update Services (WSUS) server.
You can find the updates that the sensor considers in the Server Manager (WSUS) under Roles | Windows Server Update Services | Update Services | Computers | Reports.

Remarks
Consider the following remarks and requirements for this sensor:
Remark
Description
Performance impact
This sensor has a very high performance impact. We recommend that you use no more than 50 of this sensor on each probe.
Remote PowerShell
This sensor requires that Remote PowerShell is enabled on the target system and PowerShell 3.0 on both the probe system and the target system.
Also make sure that you have at least PowerShell 3.0 installed on both the probe system and the target system.
If you receive an error message regarding issues with the WinRM connection, make sure that remote commands have been enabled in PowerShell. For more information, see the Knowledge Base: How do I enable and use remote commands in Windows PowerShell?
.NET 4.7.2 or later
This sensor requires .NET 4.7.2 or later from Microsoft on the probe system. In a cluster, install it on every cluster node.
If the framework is missing, you cannot create this sensor.
This sensor requires credentials for Windows systems.
Scanning interval
This sensor has a fixed minimum scanning interval for performance reasons. You cannot use a shorter scanning interval. Consequently, shorter scanning intervals in the Monitoring settings are not available for this sensor.
The minimum scanning interval of this sensor is 1 hour.
The recommended scanning interval of this sensor is 12 hours. We recommend this scanning interval to limit the load on the server that this sensor monitors.
IPv6
This sensor supports IPv6.
Limits
This sensor has predefined limits for several metrics.
Initial data
In certain cases, it might take some time until the sensor receives data for the first time.
Time Since Last Update channel
If the sensor cannot determine any values for the Time Since Last Update channel (for example, because the list of updates is empty), it shows the value -1s and changes to the Warningstatus.
Roaming Profiles
When monitoring a Remote Desktop Server (RDS) system with the option Roaming Profiles enabled, this sensor creates a temporary user profile folder for each scanning interval. To minimize this effect, we recommend that you set the sensor's scanning interval to at least 7 days.
You cannot add this sensor to the hosted probe of a PRTG Hosted Monitor instance. If you want to use this sensor, add it to a remote probe device.
Basic Sensor Settings
Basic Sensor Settings
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

Setting
Description
Port
Enter the number of the port to which this sensor connects. Enter an integer. The default port is 5985.
Port in SPN
Define whether to include the port number in the Service Principal Name (SPN) used for Kerberos authentication, for example, on devices where Microsoft Internet Information Services (IIS) or similar services are installed:
Exclude port in SPN (default): Do not include the port number in the SPN.
Include port in SPN: Include the port number in the SPN.
With this option, a client that uses a non-default SPN can authenticate against a remote computer that uses Kerberos authentication.
Authentication Method
Select the authentication method for the connection to the host via PowerShell:
Kerberos authentication (default): The sensor uses Kerberos authentication.
Discard result (default): Do not store the sensor result.
Store result: Store the last sensor result in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file names are Result of Sensor [ID].txt, Result of Sensor [ID].Data.txt, and Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval.
In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Description
Primary Channel
Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.
You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.
Graph Type
Define how this sensor shows different channels:
Show channels independently (default): Show a graph for each channel.
Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic. You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).
Stack Unit
This setting is only visible if you select Stack channels on top of each other above.
Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.
Inherited Settings
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
Channel
Description
Downtime
In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status
Time Since Last Update
The time passed since the last update
This channel is the primary channel by default.
The sensor always creates the channel Time Since Last Update. All other channels are optional and only show up if the sensor can retrieve respective data.
