PRTG Manual: Hyper-V Cluster Shared Volume Disk Free Sensor

The Hyper-V Cluster Shared Volume Disk Free sensor monitors free space on the disks of a Microsoft Hyper-V cluster shared volume via PowerShell.

For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
.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. For more information, see the Knowledge Base: Which .NET version does PRTG require?
Remote PowerShell	This sensor requires Remote PowerShell on the target system. In 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. For 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 WSFC PowerShell Interface on the target system. You can list all modules in the PowerShell console with the command Get-Module -ListAvailable. Here, FailoverClusters must appear. Under Windows Server 2008 (not officially supported) and Windows Server 2012 (not officially supported), 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).
Parent device	This sensor requires that the parent device is a Windows server that runs Hyper-V.
Credentials	This sensor requires credentials for Windows systems.
Unsupported characters	Make 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 more information, see the Knowledge Base: Why don't my Hyper-V sensors work after changing names?
IPv6	This sensor supports IPv6.
Performance impact	This sensor has a medium performance impact.
Knowledge Base	Knowledge Base: Why don't my Hyper-V sensors work after changing names? Knowledge Base: Where can I find more information about PowerShell sensors?
Hosted probe	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

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

diskfree
hyperv
powershell

For more information about basic sensor settings, see section Sensor Settings.

Specific Sensor Settings

Setting	Description
Disks	The name of the disk that this sensor monitors.
Result Handling	Define what PRTG does with the sensor result: Discard result (default): Do not store the sensor result. Store result: Store the sensor result and the last response 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. In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Setting

Description

Disks

The name of the disk that this sensor monitors.

Result Handling

Define what PRTG does with the sensor result:

Discard result (default): Do not store the sensor result.
Store result: Store the sensor result and the last response 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.

In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Sensor Display

Setting	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.

Setting

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.

For more information, see section Inheritance of Settings.

Channel List

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.
Free Bytes	The free space
Free Space	The free space (%) This channel is the primary channel by default.
Total	The total space
