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.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the host for which this test is to be configured.

Port

Refers to the port at which the specified host listens to. By default, this is 80.

Username

In order to monitor the target Delivery Controller 7, eG requires a special user with the following privileges;

  • The All scope and read-only privileges
  • The Allow log on locally security privilege on the Delivery Controller host

The steps for assigning such privileges to a user are discussed in the Pre-requisites for monitoring the Citrix Delivery Controller 7.x. Specify the name of such a user, here.

Password

Specify the password for the user specified in the Username text box, here.

Confirm Password

Confirm the Password by retyping it here.

Domain

Here, specify the domain to which the user specified in the Username text box belongs to.

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:

  • 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

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:

Measure Value Numeric Value
Yes 1
No 0

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:

Measure Value Numeric Value
Yes 1
No 0

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.

Total machines

Indicates the total number of machines in this group.

Number

 

Available machines

Indicates the number of machines in this delivery group that are available for a new user to connect to.

Number

Ideally, this value should be high. The detailed diagnosis of this measure if enabled, will reveal the complete details of the available desktops, such as, the desktop name, IP address, the desktop type, the catalog to which the desktop belongs, the hosting server on which the desktop operates, etc.

Percentage of used machines

Indicates the percentage of machines in this group that are currently in use by users.

Percent

Ideally, the value of this measure should be low. A value close to 100% indicates that the delivery group is about to run out of free machines. Owing to the absence of unused machines, other users who have been assigned to this delivery group will be denied access to the group upon login.
