Hypervisor Details 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 broker 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 broker and the server hosting that machine, so that connection errors (if any) can be promptly detected.

Target of the test : A Citrix Delivery Controller 7.x

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each broker that is to be monitored.

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.
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.
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.

Description

Measurement Unit

Interpretation

Broker’s connection state to hypervisor

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

This test reports one of the following values to indicate the status of the connection between the broker 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 broker 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 broker is unable to contact the hypervisor

Note:

By default, this measure reports the above-mentioned States while indicating the connection status of the broker 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 controller and the user who is accessing the hypervisor.

Is Broker’s connection to hypervisor in maintenance mode?

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

This measure reports a value Yes if the connection between the broker 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 broker 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 Broker’s connection to hypervisor in persistent?

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

This measure reports a value Yes if the connection between the broker 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 broker 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.

Is hypervisor connection in ready state?

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

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 is ready between the hosting server and the delivery controller. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.

Machines associated with this hypervisor connection

Indicates the number of machines associated with the connection between the hosting server and the delivery controller.

Number

The detailed diagnosis of the Broker’s connection state to hypervisor measure reveals the connection name, connection type, Hypervisor address, the controller and the user who is accessing the hypervisor.
