Measures reported by OraVdiDesktopTest

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.

The measures made by this test are as follows:

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.
Vm_memory Indicates the total amount of memory allocated to this desktop. MB  
Disk_space Indicates the total amount of disk space allocated to this desktop. MB  
Video_memory Indicates the total amount of video memory allocated to this desktop. MB 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.
