Hypervisor Details - Cloud Test

This test reports the status of the connection between the cloud delivery controller in the target Citrix Cloud Control Plane 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 : Citrix Cloud Control Plane

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each hypervisor with which the target Citrix Cloud Control Plane 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 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.

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.

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

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
