Remarks

  • The parent device of this sensor must be a Windows server that runs Hyper-V.
  • This sensor requires Remote PowerShell on the target device.
  • This sensor requires WSFC PowerShell Interface on the target device.
  • This sensor requires .NET 4.7.2 or later from Microsoft on the probe system.
  • This sensor requires credentials for Windows systems in the settings of the parent device.
  • This sensor supports the IPv6 protocol.
  • This sensor has a medium performance impact.

i_podYou 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.

Detailed Requirements

Requirement

Description

Remote PowerShell

This sensor uses PowerShell commands. To monitor devices with this sensor, Remote PowerShell must be enabled.

i_round_blueIn larger environments, the default memory limit for the remote shell might be insufficient. This might result in the error message The WSMan provider host process did not return a proper response. In this case, increase the memory limit for Remote PowerShell.

i_square_cyanFor more information, see the Knowledge Base: How do I enable and use remote commands in Windows PowerShell? and How can I increase memory for Remote PowerShell?

WSFC PowerShell Interface

This sensor requires the WSFC (Windows Server Failover Clustering) PowerShell Interface to be installed on the target machine. You can list all modules in the PowerShell console with the command Get-Module -ListAvailable. Here, FailoverClusters has to appear. Under Windows Server 2008 (not officially supported) and Windows Server 2012, the interface is part of the VMM Administrator Console, or the VMM 2012 Management Console.

The interface is available everywhere the WSFC feature is installed: Windows Server 2008 R2 (SP1) Full and Core (not installed by default), Microsoft Hyper-V Server 2008 R2 (SP1), and Remote Server Administration Tools (RSAT) for Windows 10, Windows 8.1, Windows 8, and Windows 7 (SP1).

.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).

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

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

Add Sensor

The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the settings that are required to create the sensor. You can change nearly all settings on the sensor's Settings tab after creation.

i_round_blueThe settings that you select in the Add Sensor dialog are valid for all sensors that you create when you finish the dialog.

Disk Free Settings

Setting

Description

Disk

Select the disks that you want to monitor. PRTG creates one sensor for each disk that you select.

i_round_blueEnable check boxes in front of the respective lines to select the items. Use the check box in the table header to select all items or to cancel the selection. In large tables, use the search function in the upper-right corner.

i_round_redMake sure that the resource names of your disks do not contain unsupported characters, especially avoid the number sign (#). In general, the sensor supports UTF-8 characters. We recommend that you do not rename resource disk names once you have set up monitoring. For detailed information, see the Knowledge Base: Why don't my Hyper-V sensors work after changing names?

Basic Sensor Settings

Click the Settings tab of a sensor to change its settings.

Setting

Description

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.

i_round_blueIf 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

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

i_round_blueThis 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.

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

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

  • hyperv
  • powershell
  • diskfree

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 (i_priority_1) to the highest priority (i_priority_5).

i_round_blueUsually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.

Description

Disks

Shows the name of the disk that this sensor monitors.

i_round_bluePRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

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 and Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval.

i_round_blueIn 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, 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.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary 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.
    i_round_redYou 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.

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 b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

Schedules, Dependencies, and Maintenance Window

i_round_blueYou cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
