Measures reported by VDIBoxImageTest
An image includes a desktop operating system (such as Windows 7 or Windows XP), a set of applications, and the VDI-in-a-Box Desktop Agent; without this agent, the vdimanager will not be able to receive updates on user sessions and desktop health. The vdimanager creates desktops from templates that consist of an image. A single image can be used by more than one template. Once an image is created, you can distribute that image to all the other servers in a grid. This test not only reports the distribution status (whether the image is successfully distributed or not) of an image, but also periodically checks the configuration of an image and reports whether the Desktop Agent is installed on the image or not. This way, the test promptly alerts you to distribution failures, points you to the reason why the vdimanager has not been receiving updates on user sessions and desktop health, and also leads you to the specific templates that have been affected by such incomplete (i.e., images without desktop agent) images.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| State |
Indicates the current status of this image. |
Number |
The values that this measure can take and their corresponding numeric values are discussed in the table below:
| Measure Value |
Description |
Numeric Value |
| Green |
Image is distributed throughout the grid or fully distributed. |
1 |
| Yellow |
Image distribution is ongoing. |
2 |
| Red |
Image distribution is complete. |
3 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating the distribution state of an image. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
|
| Image_dis |
Indicates whether this image has been distributed or is being distributed to the servers in a grid. |
|
The values that this measure can take and their corresponding numeric values are discussed in the table below:
| Measure Value |
Description |
Numeric Value |
| Published |
The image is fully distributed throughout the grid. |
1 |
| Distributing |
The image is being distributed throughout the grid. |
2 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating the distribution state of an image. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only. |
| Tot_templates |
Indicates the number of templates using this image. |
Number |
If the desktop agent is not installed on an image, then using this measure, you can easily assess the extent of the damage - this is because, this measure reports the total number of templates that will be affected by the non-availability of the desktop agent in the underlying image. To know which templates will be affected, use the detailed diagnosis of this measure. |
| HDX_avail |
Indicates whether the HDX protocol is enabled for this image or not. |
|
HDX is the default protocol that user devices use to communicate with virtual desktops provisioned by the VDI-in-a-Box appliance. HDX technology is a set of capabilities that deliver a “high definition” experience to end users of any application, on any device and over any network. This protocol provides multi-media support while using less bandwidth. It is suitable for remote access over a WAN.
The values that this measure can take and their corresponding numeric values are discussed in the table below:
| Measure Value |
Numeric Value |
| Yes |
1 |
| No |
0 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating the state of the HDX protocol. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
|
| Is_agent_installed |
Indicates whether the Desktop Agent has been installed on this image or not. |
|
If the value of this measure is No, it indicates that the desktop agent has not been installed on the image. This implies that the vdimanager will not be able to receive any communication related to user connections or desktop health from the desktops created using this image. If the value of this measure is Yes, it indicates that the desktop agent has been installed.
The numeric values that correspond to the measure values discussed above are as follows:
| Measure Value |
Numeric Value |
| Yes |
1 |
| No |
0 |
Note:
By default, this measure reports the above-mentioned Measure Values while indicating the state of the HDX protocol. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
