QVD Desktop Information Test

When users complain that they are unable to access their virtual desktops, administrators would want to know the reason for the anomaly - is it because the virtual desktop is powered-off? Is it because the virtual desktop is blocked? or is it because the desktop is in a zombie state? Besides desktop status, time and again, administrators may also want to know which desktops are powered-on, but are not effectively used by users – such desktops can be marked for deletion or can at least be powered-off, so as to prevent unnecessary resource consumption. In the same manner, administrators may also want to isolate unregistered desktops, so that they can be registered with the Server Node soon. The QVD Desktop Information test provides the inputs administrators require to take these critical decisions! This test reports the number and names of registered desktops on a Server Node, thus indirectly pointing administrators to those desktops that are yet to be registered! In addition, the test indicates the current status of the desktops, so that administrators know which desktops are usable and which are not. Moreover, the test leads administrators to powered-on desktops that have no users logged in, thus revealing idle desktops that can be removed. 

Target of the test : A Quality Virtual Desktop Node

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every QVD being monitored.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Registered desktops

Indicates the number of virtual desktops that are registered with the QVD Server Node.

Number

The detailed diagnosis of this measure if enabled, provides the details of each registered desktop – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Powered on desktops

Indicates the number of virtual desktops that are currently powered on.

Number

The detailed diagnosis of this measure if enabled, provides the details of each powered-on desktop – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Powered off desktops

Indicates the number of virtual desktops that are currently powered off.

Number

The detailed diagnosis of this measure if enabled, provides the details of each powered-off desktop – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Starting desktops

Indicates the number of virtual desktops that are currently in the Starting state.

Number

If a desktop is in the Starting state, it could mean either of the following:

  • That the HKD (House Keeping Daemon) has received the start command but is waiting until it has the resources available to move to the next machine state
  • That the VM has been started but the boot process has not yet completed

The detailed diagnosis of this measure if enabled, provides the details of each desktop in the Starting state – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Stopping desktops

Indicates the number of virtual desktops that are currently in the Stopping state.

Number

If a desktop is said to be in the Stopping state, it could mean either of the following:

  • That the HKD (House Keeping Daemon) received the stop command but is waiting for the VMA (Virtual Machine Agent) within the VM to respond to the request
  • That the VMA has responded to the stop request and the VM is in the process of shutting down

The detailed diagnosis of this measure if enabled, provides the details of each desktop in the Stopping state – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Desktops in zombie state

Indicates the number of virtual desktops that are currently in the zombie state.

Number

If a desktop is said to be in the Zombie state, it could mean either of the following:

  • That the VM is running but is not responding, and a TERM signal has been sent to the process
  • That the VM is running but is not responding, and a KILL signal has been sent to the process

The detailed diagnosis of this measure if enabled, provides the details of each desktop in the Zombie state – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Desktops in debugging state

Indicates the number of virtual desktops that are currently in debugging state.

Number

The detailed diagnosis of this measure if enabled, provides the details of each desktop in the debugging state – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Blocked desktops

Indicates the number of virtual desktops that have been blocked by the administrator.

Number

Virtual machines can enter a Blocked state automatically if they fail to start correctly or if there is some problem with their network configuration or with the QVD-VMA that should be running on each virtual machine. However, it is also possible to force the Blocked state using the QVD-WAT. This is usually done if an administrative task needs to be performed on the Virtual Machine, and the administrator does not want anybody to be accessing the virtual machine at the same time.

The detailed diagnosis of this measure if enabled, provides details of each blocked desktop – these details include the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.

Desktops with users

Indicates the number of powered on virtual desktops with users logged in.

Number

The detailed diagnosis of this measure if enabled, provides the details of each desktop with a user – these details include, the desktop ID, name of the desktop, the user who is logged into the desktop, IP address, the OSF associated with the desktop, the DI tag of the desktop, the disk image using which the desktop was created and the connection status of the desktop.

Desktops without users

Indicates the number of powered on virtual desktops without any users logged in.

Number

The detailed diagnosis of this measure if enabled, provides the details of desktops to which no user is currently logged in – such details include, the desktop ID, name of the desktop, the user who is registered with the desktop during desktop creation, IP address, the OSF associated with the desktop, the DI tag of the desktop, the disk image using which the desktop was created and the connection status of the desktop.

 

The detailed diagnosis of the Registered desktops measure (see Figure 1), lists the details of each registered desktop such as the desktop ID, name of the desktop, the IP address, the OSF associated with the desktop, the DI tag of the desktop and the disk image using which the desktop was created.
