PRTG Manual: Windows Updates Status (PowerShell) Sensor

Remote PowerShell

This sensor uses PowerShell commands. This sensor requires that Remote PowerShell access is enabled on 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 to be installed on the probe system (on every cluster node, if on a cluster probe).

If the framework is missing, you cannot create this sensor.

For more information, see the Knowledge Base: Which .NET version does PRTG require?

Sensor Name

Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.

If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?

Parent Tags

The tags that the sensor inherits from its parent device, parent group, and parent probe.

This setting is for your information only. You cannot change it.

Tags

Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.

It is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).

For performance reasons, it can take some minutes until you can filter for new tags that you added.

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

• windowsupdatesstatus

Priority

Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority () to the highest priority ().

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. Choose between:

• Kerberos authentication (default): The sensor uses Kerberos authentication.
• Negotiate authentication: The sensor uses Negotiate authentication.
  For more information about Negotiate authentication, see the Knowledge Base: Facing issues with the Windows Updates Status (PowerShell) sensor - can you help me?

Result Handling

Define what PRTG does with the sensor result:

• Discard result: 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.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed 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 different channels are shown for this sensor:

• 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 enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are stacked 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.

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.
