Delivery Groups Test
With the help of this test, you can determine the maintenance mode of each delivery group managed by the monitored broker, and track the usage of desktops within each group. Unregistered desktops, CPU-intensive desktops, disconnected desktops, and desktops available to users, which are managed by this broker, can thus be quickly and accurately isolated.
Target of the test : Citrix Delivery Controller 7.x
Agent deploying the test : An internal agent
Outputs of the test : One set of results for each delivery group that is configured with the Delivery Controller 7.

Report by Machine Type |
By default, this flag is set to Yes indicating that the individual descriptors of this test - i.e., the delivery groups- are classified based on their machine type; in other words, the delivery groups will be listed either under Server OS Machines or Desktop OS Machines based on their machine type. If you do not want to group the delivery groups based on their machine types, set this flag to No. |
|
Show Available Machines DD |
By default, this flag is set to No. This implies that by default, detailed metrics will not be available for the Available machines measure of this test. To enable detailed diagnosis for this measure, you can set this flag to Yes. In this case, you will be able to view the complete details of all machines that are currently available in each delivery group managed by the broker. |
|
Show Registered Machines DD |
By default, this flag is set to No. This implies that by default, detailed metrics will not be available for Registered machines measure of this test. To enable detailed diagnosis for this measure, you can set this flag to Yes. In this case, you will be able to view the complete details of the machines (in each delivery group) that are currently registered with the broker being monitored. |
|
Show Powered On Machines DD |
By default, this flag is set to No. This implies that by default, detailed metrics will not be available for Powered on machines measure of this test. To enable detailed diagnosis for this measure, you can set this flag to Yes. In this case, you will be able to view the complete details of the powered on machines in each delivery group that is managed by the broker. |
|
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the 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:

| Measurement | Description | Measurement Unit | Interpretation | ||||||
|---|---|---|---|---|---|---|---|---|---|
|
Is delivery group available? |
Indicates whether this delivery group is available or not. |
|
This measure reports the value Yes if a delivery group is available, and reports No if it is not available. The numeric values that correspond to the above-mentioned measure values are as follows:
Note: By default, this measure reports the above-mentioned Measure Values while indicating the availability of the delivery group. However, in the graph of this measure, the same will be represented using the numeric equivalents – 1 and 0 only. The detailed diagnosis of this measure if enabled, lists the name of the delivery group, the description, the zone to which the group belongs, the desktop kind, whether Secure ICA is required, the number of sessions supported, whether the machine needs to be shut down after use, Powered on status of the machine if user is assigned, Powered on status of the machine during peak period if user is assigned , the published name of the machine, the delivery type, and the AppDisk name. |
||||||
|
Is delivery group in maintenance mode? |
Indicates whether this delivery group is in a maintenance mode or not. |
|
Delivery groups are typically put on maintenance mode, if the connections to the machines within the group are to be temporarily stopped so that maintenance tasks are carried out. XenDesktop has no control over delivery groups that are in maintenance mode. No user can log on to a machine in this state. This measure reports the value Yes if a delivery group is in the maintenance mode, and reports No if it is not. The numeric values that correspond to the above-mentioned Measure Values are as follows:
Note: By default, this measure reports the above-mentioned Measure Values while indicating the maintenance status of the desktop group. However, in the graph of this measure, the same will represent the maintenance modes using the numeric equivalents – 1 and 0 only. |
||||||
|

The Power management feature of Citrix allows you to only start and stop certain machines during certain periods. For example, you may have a delivery group of desktops for users that work normal business hours. After 5pm, and as long as the user has been disconnected for a short period of time, the machine could be powered off automatically to reduce resource cost. If this measure reports a non-zero value, then you can use the detailed diagnosis of the measure to know which machines do not have the Power management feature enabled. |
