Delivery Groups - Cloud Test

With the help of this test, you can determine the maintenance mode of each delivery group managed by the cloud delivery controller, 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 controller, can thus be quickly and accurately isolated.

Target of the test : Citrix Cloud Control Plane

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each delivery group that is configured with the target Citrix Cloud Control Plane

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.
Customer ID	When configuring the Citrix Cloud service, you should have created an API client on the cloud, so that any external program can communicate with the cloud. This API client is tied to a customer ID. The Citrix Cloud API requires this customer ID, when calling REST APIs. To determine the customer ID that is mapped to the API client you created, refer to Determining the Customer ID Mapped to an API Client.
Secure Client File Path	When creating the API client on the cloud, you will be provided with an ID and a Secret for your client. Downloading this information saves a file named secureclient.csv. The eG agent uses the ID and Secret stored in this file to connect to the Citrix Cloud API. This is why, you will have to configure the Citrix Cloud Connectivity test with the full path to the secureclient.csv. Note: Before specifying the path of the secureclient.csv file, make sure that the API client is created and this file downloaded by a valid Citrix cloud user with Read-only administrator rights to virtual apps/desktops. To know how to create this user on the cloud, refer to theCreating a New Citrix Cloud User for Monitoring PurposestopicTo know how this user can create an API client on the cloud, refer to Creating API Client on the Citrix Cloud.
Proxy Host and Proxy Port	If the Citrix Cloud Connector communicates with the Citrix Cloud via a proxy, then, you also need to configure the eG agent on the connector with the proxy server details. This will enable the eG agent to connect to the Citrix cloud without a glitch, and pull metrics. To facilitate this communication. do the following: Specify the IP address/fully-qualified host name of the proxy server, against PROXY HOST. Specify the port at which the Proxy server listens for requests from the eG agent, against PROXY PORT. By default, both these parameters are set to none, indicating that the eG agent does not communicate with the Citrix Cloud via a proxy. Note: Before configuring these test parameters, make sure that the proxy server settings are imported to the eG agent side from the connector. To know how to achieve this, refer to Configuring the eG Agent with Proxy Server Settings. To know what values you should configure these parameters with, do the following: Login to the system hosting the Citrix Cloud Connector being monitored. Open the Internet Explorer browser on that system, and click on the icon provided at the right corner of that browser. Clicking the icon will invoke a menu. Choose Internet Optionsfrom the menu. Then, select the Connections tab in the Internet Options window that appears. Now, click the LAN Settings button. This will open the Local Area Network (LAN) Settings window. In the Proxy Server section of this window, you will find that the Use a proxy server for your LAN check box is enabled. Configure the PROXY HOST and PROXY PORT parameters with the IP address and port numbers displayed in the Address and Port text boxes (respectively) under that check box. If the Use a proxy server for your LAN check box is not enabled, then it means that the connector is not communicating with the cloud via a proxy. In this case, you need not change the default configuration for these parameters.

Unused Machines In Days	In some environments, a few machines in the delivery groups may not be logged in by any user for long period of time. Even if users are not logged on, the machines continued to consume resources unnecessarily leading to resource wastage. The resources used by those machines cannot be released or allocated to other machines until the resources are properly released. Therefore, it is necessary for administrators to identify the machines that are not used for long period of time to avoid unnecessary resource wastage. To achieve this, administrators can use the Unused Machines In Days parameter. Administrators can specify the number of days against this parameter beyond which this test should count the machines as "unused". By default, this parameter is set to 30 days. However, administrators can override this default value depending upon their need.
Region Endpoint	By default, US is chosen from this list indicating that this test will report metrics for those organizations whose users and resources are located in the United States region. Sometimes, the eG agent may collect the required metrics with a minor time delay due to the users and resources being monitored are in a different region. To avoid such time delays and to ensure end-user proximity and offer the best user experience, administrators are allowed to change the region based on where most of the users and resources are located. For instance, if the users and resources are located in the Asia-Pacific South region or approximately nearer to the Asia-Pacific South region, then, administrators need to choose 'AP-S' from this list. However, from this list, administrators are required to choose only the region that they had chosen when they signed in for the first time after onboarding their organization to the target Citrix Cloud.
DD Frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.
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.

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.
