Horizon Desktop Pools Test

This test monitors the status and usage of each desktop pool configured on a VMware Horizon Connection Server.

Target of the test : A VMware Horizon Connection server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each desktop pool configured on the VMware Horizon Connection Server being monitored

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed

Host

The host for which the test is to be configured

Port

Refers to the port used by VMware Horizon Connection Server. The default port number is NULL.

Connection Server name

Specify the name of the target VMware Horizon Connection Server that is to be monitored.

User name

By default, eG Enterprise uses a dual approach i.e., uses VMware PowerCLI and LDAP queries to collect metrics from the target VMware Horizon Connection Server 7 (or above). This dual approach ensures that the metrics are collected more faster than the LDAP query-only approach used for the prior versions of the VMware Horizon Connection Server. Administrators need to install the VMware PowerCLI on the target VMware Horizon Connection server and configure the eG agent to communicate with that CLI to pull the metrics. PowerCLI is a command-line and scripting tool built on Windows PowerShell, which enables easy management, configuration, and automation of vSphere and vCloud environments. With the help of this CLI, the eG agent collects metrics from the target server more quickly than the LDAP approach that was used to collect metrics from VMware Horizon Connection Server version 6 and below. In order to collect metrics using VMware PowerCLI, administrators need to specify the name of the user possessing read-only administrator role in the VMware Horizon Management Console.

Password

Specify the password corresponding to the user here.

Confirm Password

Confirm the password by retyping it here.

Domain Name

  • Specify the name of the domain to which the VMware Horizon Connection Server belongs to. If the target VMware Horizon Connection Server does not belong to any domain, specify none here.
  • Report Total

    By default, this flag is set to false. In this case therefore, the test will only report metrics for every desktop pool of the VMware Horizon Connection Server. If this flag is set to true, then the test will report metrics for a Total descriptor – the metrics reported by this descriptor will be aggregated across all desktop pools of the target VMware Horizon Connection Server. This way, administrators will receive in-depth insights into the functioning of the desktop pools.

    Show Total Desktop DD

    By default, this flag is set to No, indicating that this test will not report detailed diagnostics for the Total desktops measure. This means that the test, by default, will not capture and store the details of every desktop in a pool, in the eG database. This default setting is ideal for large VDI infrastructures, where a single pool can contain hundreds of desktops, as it can help conserve space in the eG database and reduce the strain on the database. However, if your eG database is well-sized and you want to view the complete list of desktops in a pool, enable the detailed diagnosis capability of the Total desktops measure by setting this flag to Yes.

    Remote Session DD

    By default, this flag is set to No, indicating that this test will not report detailed diagnostics for the Remote Sessions measure. This means that the test, by default, will not capture and store the details of the remote sessions to each desktop in a desktop pool, in the eG database. This default setting is ideal for large VDI infrastructures, where a single pool can contain hundreds of desktops, as it can help conserve space in the eG database and reduce the strain on the database. However, if your eG database is well-sized and you want to view the complete list of remote sessions to the desktops in a pool, enable the detailed diagnosis capability of the Remote Sessions measure by setting this flag to Yes.

    Disconnected Desktop DD

    By default, this flag is set to No, indicating that this test will not report detailed diagnostics for the Disconnected Desktops measure. This means that the test, by default, will not capture and store the details of the desktops that were disconnected from a desktop pool, in the eG database. This default setting is ideal for large VDI infrastructures, where a single pool can contain hundreds of desktops, as it can help conserve space in the eG database and reduce the strain on the database. However, if your eG database is well-sized and you want to view the complete list of desktops that were disconnected from a pool, enable the detailed diagnosis capability of the Disconnected Desktops measure by setting this flag to Yes.

    Disconnected Application DD

    By default, this flag is set to No, indicating that this test will not report detailed diagnostics for the Disconnected Applications measure. This means that the test, by default, will not capture and store the details of the applications (in each desktop pool) that were disconnected from the View Client, in the eG database. This default setting is ideal for large VDI infrastructures, where a single pool can contain hundreds of desktops, as it can help conserve space in the eG database and reduce the strain on the database. However, if your eG database is well-sized and you want to view the complete list of applications that were disconnected from the View Client, enable the detailed diagnosis capability of the Disconnected Applications measure by setting this flag to Yes.

    Maintenance Desktop DD

    By default, this flag is set to No, indicating that this test will not report detailed diagnostics for the Maintenance Desktops measure. This means that the test, by default, will not capture and store the details of the desktops that were in Maintenance mode in a desktop pool, in the eG database. This default setting is ideal for large VDI infrastructures, where a single pool can contain hundreds of desktops, as it can help conserve space in the eG database and reduce the strain on the database. However, if your eG database is well-sized and you want to view the complete list of desktops that were in Maintenance mode in a desktop pool, enable the detailed diagnosis capability of the Maintenance Desktops measure by setting this flag to Yes.

    DD Frequency

    Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 3:1. This indicates that, by default, detailed measures will be generated every third 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 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.
