Templates Details Test

Templates are the molds from which desktops are created. You can use templates to create uniform virtual desktops that meet your specifications. Templates consist of an image and policies. The image contains the operating systems and applications that run on the desktop. Policies, which you set while creating the template, are characteristics such as how many desktops to create and how much RAM to allocate to the desktops. Using the Templates Details test, you can determine the current status of the desktops created using each template configured using the vdimanager. This way, you can figure out how many desktops are currently in use and how many are broken.

Target of the test : A VDI-in-a-Box Manager

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each template.

Configurable parameters for the test
Parameters Description

Test period

This indicates how often should the test be executed.

Host

The host for which this test is to be configured.

Port

The port at which the specified host listens to.

VDI in a Box Host

The IP address of the vdimanager that is being monitored.

VDI in a Box Username, VDI in a Box Password, and Confirm Password

The test needs to log on to the VDI-in-a-Box appliance to pull out the metrics of interest. For this purpose, you need to configure the test with the credentials of a user with login rights to the appliance. By default, the appliance supports a root user named root (with the default password root) and a Read-only user named kvm (with the default password kaviza123). If you prefer not to expose the credentials of the root user, then you can configure the VDI in a Box Username and VDI in a Box Password parameters with the credentials of the user kvm. Confirm the password of this user by retyping it in the Confirm Password text box.

Note:

The default password of user kvm is kaviza123. If this is changed, then make sure you configure the VDI in a box password parameter with the new password.

SSH Port

Specify the SSH port number of the vdimanager. By default, this is 22.

Detailed Diagnosis

To make diagnosis more efficient and accurate, eG Enterprise 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 abnormalfrequencies configured for the detailed diagnosis measures should not be 0. 
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Desktops in use

Indicates the number of desktops created from this template that are currently in use.

Number

This refers to the number of desktops to which a user is currently logged into.

The detailed diagnosis of this measure will list the names of desktops that are currently in use.

Desktops not in use

Indicates the number of desktops created from this template that are currently not in use.

Number

 

Desktops utilization

Indicates the percentage of desktops created from this template that are currently in use.

Percent

A high value for this measure indicates that too many desktops are in use. This in turn implies that very few desktops are currently available for usage.

Desktops pre-started for instant login

Indicates the number of desktops created from this template that are ready for login – i.e., the number of new desktops.

Number

 

Desktops preserved for subsequent use

Indicates the number of desktops created from this template that were in use in the past, but the user has currently logged out.

Number

This refers to the number of desktops that are ‘on hold’.

You can use the detailed diagnosis of this measure to know which desktops are on hold currently.

Broken desktops

Indicates the number of desktops created from this template that are broken.

Number

A desktop in an unknown state has the status "Broken" and is not available to users. Causes for broken desktops are as follows:

  • Desktops are getting stuck in startup within Windows due to missing or incorrect startup configuration, e.g., a bad product key or incorrectly specified domain credentials. This can be diagnosed by using a console client to directly look at the console of the broken desktop to see if it is waiting on user input. This is the most common reason desktops are broken, and this cause can be mitigated by thoroughly testing working desktops before saving them as templates.
  • The server is too heavily loaded to start new desktops.
  • The disk space on the datastore is exhausted.
  • The computer name allocation system has been exhausted.
  • The MAC address allocation system has been exhausted.
  • The template image has been lost.

To know which desktops are broken, use the detailed diagnosis of this measure.

Desktops being pre-started for instant login

Indicates the number of desktops created from this template that are being pre-started for instant login.

Number

 

To know which desktops are currently in use for a template, use the detailed diagnosis of the Desktops in use measure.
