Hypervisor Test

This test reports the status of the connection between the delivery controller and each server that hosts the machines. In the absence of a healthy connection between the two, the controller may not be able to provision machines on-demand.

If users complaint of any delay in the servicing of their machine requests, you may want to use this test to check the connection status between the controller and the server hosting that machine, so that connection errors (if any) can be promptly detected.

Target of the test : A controller in a Citrix XA/XD Site 7.x

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each hypervisor with which the target controller communicates.

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 the test is being configured.

Port

The port number at which the specified Host listens to. By default, this is 80.

Domain, Username
and Password

To connect to a delivery controller in a site and pull out metrics from it, the eG agent requires Farm Administrator rights. In order to configure the eG agent with Farm Administrator privileges, specify the Domain to which the target controller belongs and enter the credentials of a user who has the Farm Administrator rights in the Username and Password text boxes. This user should also be assigned the Allow log on locally privilege on the Citrix XA/XD Site 7.x host. The steps for assigning the Allow log on locally privilege are explained in the Monitoring the Citrix XA/XD Site 7.x topic.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite 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

State of controller’s connection to hypervisor

Indicates the status of the connection between the controller and this hosting server.

 

This test reports one of the following values to indicate the status of the connection between the controller and a hosting server:

  • On
  • InMaintenanceMode
  • Unavailable

The numeric values that correspond to the above-mentioned states are as follows:

State Numeric Value Description
On 1 Indicates that the controller is in contact with the hypervisor
InMaintenanceMode 2 Indicates that the hosting server (e.g., XenServer, Hyper-V) through which machines are managed, is under maintenance
Unavailable 3 Indicates that the controller is unable to contact the hypervisor

Note:

By default, this measure reports the above-mentioned States while indicating the connection status of the controller and the hypervisor. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents - 1 to 3 – only.

The detailed diagnosis capability of this measure if enabled, reveals the connection name, connection type, Hypervisor address, the preferred controller, the zone to which the controller belongs, and the user who is accessing the hypervisor.

Is controller’s connection to hypervisor in maintenance mode?

Indicates whether the connection between the controller and the hosting server is in maintenance mode.

 

This measure reports a value Yes if the connection between the controller and the hosting server is in maintenance mode and No if otherwise.

The numeric values corresponding 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 whether the connection between the controller and the hosting server is in maintenance mode. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 0 or 1 only.

Is controller’s connection to hypervisor in persistent?

Indicates whether/not the connection is persistent between the controller and the hosting server.

 

This measure reports a value Yes if the connection between the controller and the hosting server is persistent and No if otherwise.

The numeric values corresponding 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 whether the connection between the controller and the hosting server is persistent. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 0 or 1 only.

Is local storage caching enabled?

Indicates whether the local storage caching is enabled or not.

 

This measure reports a value Yes if the local storage caching capability is enabled and No if otherwise.

The numeric values corresponding 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 whether the local storage caching capability is enabled. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 0 or 1 only.

Is provisioning service used to create VMs?

Indicates whether/not the provisioning service is used to create provisioned machines.

 

This measure reports a value Yes if the provisioning service is used to create provisioned machines and No if otherwise.

The numeric values corresponding 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 whether the provisioning service is used to create provisioned machines. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents i.e., 0 or 1 only.

The detailed diagnosis of the State of the controller’s connection to Hypervisor measure reveals the connection name, connection type, Hypervisor address, the preferred controller, the zone to which the controller belongs, and the user who is accessing the hypervisor.
