Measures reported by FarmDesktopsTest
Typically, a DDC manages virtual desktops as desktop groups, with each group containing virtual desktops of a particular type - a group therefore, can include desktops that are of type pooled, pre-assigned, or assigned on first use.
Virtual desktops in pooled groups are allocated to users on a per-session, first-come-first-served basis. You can configure pools of VMs so that any change that the user makes to the desktop during a session is lost when the user logs off from the desktop. Virtual desktops in pre-assigned groups are permanently assigned to an individual user as soon as the group is created. Whenever a user requests a desktop, they are always connected to the same one. As a result, the user can safely customize the desktop to suit his or her own needs. Virtual desktops in assigned-on-first-use groups are permanently assigned to the first user to connect to them. As with pre-assigned desktops, the user can then safely customize the desktop.
For each such desktop type in a farm, this test reports the number of desktops of that type managed by the DDC, and monitors how effectively these desktops have been utilized. Note that the Assigned descriptor of this test reports measures for both the pre-assigned and assigned-on-first-use desktops. In addition, this test reports a set of measures for a Total descriptor, which reveals the availability and usage of desktops across types.
Note that this test will work only if the DDC being monitored is the 'master' in a DDC farm. If not, this test will not work.
The measures
made by this test are as
follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Powered_On_VDs |
Indicates the number of virtual desktops of this type that are currently powered on.
|
Number |
To know the details of the powered-on desktops, use the detailed diagnosis of this measure. The detailed diagnosis will reveal the name of the powered-on desktops, the desktop group to which they belong, and the user to whom they have been assigned (in case of the Assigned descriptor; for Pooled desktops the Assigned User column will typically be empty).
|
| Powered_Off_VDs |
Indicates the number of virtual desktops of this type that are currently powered off.
|
Number |
To know the details of the powered-off desktops, use the detailed diagnosis of this measure.
|
| Vds_With_Users |
Indicates the number of virtual desktops of this type that are currently in use.
|
Number |
To know the details of the desktops that are in use, use the detailed diagnosis of this measure. The detailed diagnosis will reveal the name of the desktops that are being used, the desktop group to which they belong, the user to whom they have been assigned (in case of the Assigned descriptor; for Pooled desktops, the Assigned User column will typically be empty), the user who is currently logged in to the desktop, and current status of the desktop.
|
| Idle_VDs |
| Number |
To know the details of the desktops that are free, use the detailed diagnosis of this measure.
|
| Not_Registered_VDs |
Indicates the number of virtual desktops that are currently unregistered.
|
Number |
To know the details of the unregistered desktops, use the detailed diagnosis of this measure. The detailed diagnosis will reveal the name of the desktops that are unregistered, the desktop group to which they belong, and the user to whom they have been assigned (in case of the Assigned descriptor; for Pooled desktops, the Assigned User column will typically be empty.
|
| Per_VDs_With_Users |
Indicates the percentage of virtual desktops that are currently in use.
|
Percent |
A high value for this measure is a cause for concern, as it indicates that the virtual desktops of this type have been utilized excessively. This can degrade the performance of the host on which the desktops are operating.
|
| Total_VDs
|
Indicates the total number of virtual desktops of this type.
|
Number |
|
| Unknown_VDs
|
Indicates the number of virtual desktops that are currently in an 'Unknown' powerstate.
|
