Measures reported by CtxXcXDCatalogTest

In XenDesktop, collections of virtual machines (VMs) or physical computers of the same type are managed as a single entity called a catalog. To deliver desktops to users, the machine administrator creates a catalog of machines and the assignment administrator allocates machines from the catalog to users by creating delivery groups.

This test auto-discovers the catalogs managed by the XenDesktop site being monitored, and reports useful statistics related to each catalog, which reveal:

  • The catalog type;

  • The type of desktops allocated to each catalog;

  • The availability, usage, and assignment of desktops in each catalog

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Allocation_type Indicates the allocation type of the machines available in this catalog. Number This measure can report any one of the following values:

  • Static

  • Permanent

  • Random

  • Unknown

The table below provides the numeric values that correspond to the allocation types listed above, and a brief description of each type:

Allocation Type Numeric Value Description
Static 1 Indicates that the machines in this catalog are either assigned by the administrator or assigned on first use to users. This assignment will change only when the administrator explicitly changes the assignments.
Permanent 2 Indicates that the machines in this catalog are permanently assigned to the user.
Random 3 Indicates that the machines in this catalog are picked in random and are temporarily assigned to the user.

Note:

By default, this measure reports the Allocation Types listed in the table above. However, the graph of this measure will represent the allocation types using their corresponding numeric equivalents – i.e., 1 to 3.

The detailed diagnosis of this measure if enabled, lists the catalog to which the machine belongs, the zone to which the machine catalog belongs, the machine type, the number of sessions supported by the machine i.e, either Single session or Multi session, the location used for storing user data, the provisioning type and the scopes associated with the chosen catalog.
Is_machines_physical Indicates whether/not the machines in this catalog are power managed by the broker. Number This measure reports a value Yes if the machines are power managed by the broker and No, if otherwise.

The table below provides the numeric values that correspond to the above mentioned values:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports whether the machines are power managed by the broker or not. However, the graph of this measure will be represented using their corresponding numeric equivalents – i.e., 0 or 1.
Assigned_desktops Indicates the number of assigned machines (to users) in this catalog that are within delivery groups. Number  
Avail_assigned_desktops Indicates the number of machines in this catalog that are available to users within delivery groups. Number  
Avail_unassign_desktops Indicates the number of machines within the delivery groups that are not yet assigned to users. Number  
Unassigned_desktops Indicates the number of unassigned machines in this catalog within the delivery groups but are still used in the pool. Number  
Used_desktops Indicates the number of machines in this catalog that are within delivery groups. Number  
Number_of_machines Indicates the total number of machines in this catalog. Number  
Available_desktops Indicates the number of machines from this catalog that are made available for the delivery groups. Number  
Available_machines Indicates the number of machines available in this catalog. Number  
Used_machines Indicates the number of machines that are already in use in this catalog. Number A value close to the value reported by the Available_machines measure indicates that the catalog is being over-utilized. Administrators may need to add additional machines to the catalog.
Percentage_of_machines Indicates the percentage of machines that were already in use in this catalog. Percent A high value for this measure is a cause of concern.
Disconnected_machines Indicates the number of machines that were disconnected from this catalog. Number
