VDI Desktop Information Test

Virtual machines are used to run the operating systems which render the desktops. They are controlled by a hypervisor, such as Oracle VDI Hypervisor, Microsoft Hyper-V, and VMware Infrastructure. They cycle through traditional machine states such as powered off and running. This test auto-discovers the desktops configured on all desktop providers managed by the broker and reports the current 'machine state' of each desktop. This way, you can quickly isolate powered-off desktops and unknown desktops. In addition, the test captures the 'desktop state' for each desktop. Desktop states are used to accomplish the following:

  • Implement the desktop lifecycle
  • Synchronize Oracle VDI Core hosts and virtualization platform
  • Serve as a tool for monitoring and analyzing the system state

Knowledge of desktop states enables you to determine which desktops are available, which ones are idle, and which are being used currently. Besides the above, the test also reveals the amount of memory and disk space that each desktop has been configured with.

Target of the test : An Oracle VDI Broker

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for each desktop managed by the Oracle VDI broker being monitored.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured.

Port

The port number at which the specified Host listens to.

SudoPath

This test executes certain privileged VDA (Virtual Desktop Access) commands to pull out the desired metrics from the broker. To enable the test to run these commands, you first need to install a sudo package on the broker host. The procedure for installing this package is detailed in Pre-requisites for Monitoring the Oracle VDI Broker in an Agent-based Manner. Once the package is installed, you need to specify the full path to the install directory of the sudo package in the SudoPath text box.

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

Machine state

Indicates the current 'machine state' of this desktop.

 

 

This measure reports one of the states listed below:

  • Powered off
  • Running
  • Suspended
  • Unknown

The table below discusses the numeric values that correspond to each of the states mentioned above:

State Numeric Value
Powered off 0
Running 1
Suspended 2
Unknown 3

Note:

Typically, this measure will report the States indicated in the table above. However, in the graph of this measure, the machine state will be represented using the numeric equivalents only - i.e., 0 to 3.

Use the detailed diagnosis of this measure for complete details of the desktop such as the user assigned to the desktop, the assignment type, the operating system and IP address of the desktop, the storage server name, the ZFS volume used by the desktop..

Desktop state

Indicates the current 'desktop state' of this desktop.

Number

This measure reports one of the states listed below:

  • Used
  • Available
  • Idle
  • Unresponsive
  • Reserved

The table below discusses the numeric values that correspond to each of the states mentioned above:

State Numeric Value
Used 1
Available 2
Idle 3
Unresponsive 4
Reserved 5

Note:

Typically, this measure will report the States indicated in the table above. However, in the graph of this measure, the machine state will be represented using the numeric equivalents only - i.e., 1 to 5.

Ram allocated

Indicates the total amount of memory allocated to this desktop.

MB

 

Disk capacity

Indicates the total amount of disk space allocated to this desktop.

Number

 

Total video memory

Indicates the total amount of video memory allocated to this desktop.

Number

Video memory is a term generally used in computers to describe some form of writable memory, usually RAM, dedicated to the purpose of holding the information necessary for a graphics card to drive a display device.
