PRTG Manual: Citrix XenServer Virtual Machine Sensor
The Citrix XenServer Virtual Machine sensor monitors a virtual machine (VM) on a XenServer via HTTP.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
Performance impact |
This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe. |
.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? |
Parent device |
|
Credentials |
This sensor requires credentials for VMware/XenServer. |
TLS 1.2 |
This sensor does not fully support Transport Layer Security (TLS) 1.2 connections. You cannot add it to XenServers with the security protocol setting "TLS 1.2 only". |
IPv4 |
This sensor only supports IPv4. |
Add Sensor dialog |
PRTG requests a full list of all VMs that are configured on the Citrix XenServer, including VMs that do not run. Therefore, it might take a few seconds before the Add Sensor dialog loads. |
In a XenServer pool, there is one "pool master" that manages the pool. Incoming queries on any host are automatically forwarded to the pool master. If you want to monitor your VMs or host servers, create respective sensors on a device that represents one host server of your pool. Internal processes make sure that monitoring takes place and continues independently from the physical host.
In the device tree, the sensors for VMs always remain on the host you originally created them on, also if they are currently running on a different host.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- xenvmsensor
For more information about basic sensor settings, see section Sensor Settings.
Setting |
Description |
---|---|
UUID |
The universally unique identifier (UUID) of the VM that this sensor monitors. PRTG shows this value for reference purposes only. We strongly recommend that you only change it if the Paessler support team explicitly asks you to do so. Wrong usage can result in incorrect monitoring data. |
Name |
The name of the VM that this sensor monitors. |
Setting |
Description |
---|---|
Result Handling |
Define what PRTG does with the sensor result:
This option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance. In a cluster, PRTG stores the result in the PRTG data directory of the master node. |
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:
|
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. |
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.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

CPU [Value] Usage |
The CPU usage This channel is the primary channel by default. |
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 |
Memory Available |
