AVD Host Pools - Overview Test

Use the AVD Host Pools test to know the constitution of every host pool managed by your AVD broker. Be instantaneously alerted to changes in a pool's constitution/configuration.

For each host pool, this test reports the number and names of applications, application groups, desktops, and session hosts in that pool. Alerts are sent out if session hosts are added to or removed from any pool. The status of every host pool is also tracked, and the unavailability of a pool is promptly reported.

Target of the Test: A Microsoft AVD Broker

Agent deploying the test: A remote agent

Output of the test: One set of results for each AVD host pool managed by the target AVD broker, in each resource group of the configured subscription

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Subscription ID

Specify the GUID which uniquely identifies the Microsoft Azure Subscription to be monitored. To know the ID that maps to the target subscription, do the following:

  1. Login to the Microsoft Azure Portal.

  2. When the portal opens, click on the Subscriptions option (as indicated by Figure 1).

    Figure 1 : Clicking on the Subscriptions option

  3. Figure 2 that appears next will list all the subscriptions that have been configured for the target Azure AD tenant. Locate the subscription that is being monitored in the list, and check the value displayed for that subscription in the Subscription ID column.

    Figure 2 : Determining the Subscription ID

  4. Copy the Subscription ID in Figure 2 to the text box corresponding to the SUBSCRIPTION ID parameter in the test configuration page.

Tenant ID

Specify the Directory ID of the Azure AD tenant to which the target subscription belongs. To know how to determine the Directory ID, refer to Configuring the eG Agent to Monitor the Microsoft Azure App Service

Client ID and Client Password

The eG agent communicates with the target Microsoft Azure Subscription using Java API calls. To collect the required metrics, the eG agent requires an Access token in the form of an Application ID and the client secret value. To know how to determine the Application ID and the key, refer to Configuring the eG Agent to Monitor the Microsoft Azure App Service. Specify the Application ID of the created Application in the Client ID text box and the client secret value in the Client Password text box.

Proxy Host

In some environments, all communication with the Azure cloud be routed through a proxy server. In such environments, you should make sure that the eG agent connects to the cloud via the proxy server and collects metrics. To enable metrics collection via a proxy, specify the IP address of the proxy server and the port at which the server listens against the Proxy Host and Proxy Port parameters. By default, these parameters are set to none, indicating that the eG agent is not configured to communicate via a proxy, by default.

Proxy Username, Proxy Password and Confirm Password

If the proxy server requires authentication, then, specify a valid proxy user name and password in the Proxy Username and Proxy Password parameters, respectively. Then, confirm the password by retyping it in the Confirm Password text box.

Detailed Diagnosis

To make diagnosis more efficient and accurate, 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.
Measures made by the test:
Measurement Description Measurement Unit Interpretation

Status

Indicates whether/not this host pool is available currently.

 

The values that this measure reports and their corresponding numeric values are listed in the table below:

Measure Value Numeric Value
Unavailable 0
Available 1

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current status of the host pool. In the graph of this measure however, the same is represented using the numeric equivalents only.

Use the detailed diagnosis of this measure to view the friendly name of the host pool, host pool type, load balancer type, and maximum number of sessions allowed on the host pool.

Total application groups

Indicates the number of application groups installed on the session hosts in this pool.

Number

An app group is a logical grouping of applications installed on session hosts in the host pool.

Use the detailed diagnosis of this measure to know which application groups are managed by the host pool.

Total applications

Indicates the total number of RemoteApps individually selected and published to all the RemoteApp application groups in this host pool.

Number

Use the detailed diagnosis of this measure to know which RemoteApps are published to which application group in the host pool.

Total desktops

Indicates the total number of full desktops grouped into desktop application groups in this host pool.

Number

Use the detailed diagnosis of this measure to know which desktops are published to which application group in the host pool.

Total session hosts

Indicates the total number of session hosts in this host pool.

Number

The detailed diagnosis of this measure reveals the names of the session hosts in the host pool, and their current status. For each session host, the detailed metrics further reveals whether new sessions are allowed or not in the session host, when the last heart beat was sent by the session host, the total number of sessions on the host, and whether update succeeded/failed on the host. From this, you can quickly identify the session hosts that have been down - i.e., that have not sent heart beats - for a long time. The hosts on which upgrade failed can also be pinpointed.

Session hosts added

Indicates the number of session hosts that were newly added to this host pool.

Number

Use the detailed diagnosis of this measure to know which session hosts were added recently.

Session hosts removed

Indicates the number of session hosts that were recently removed from this host pool.

Number

Use the detailed diagnosis of this measure to know which session hosts were removed recently.

Use the detailed diagnosis of the Status measure to view the friendly name of the host pool, host pool type, load balancer type, and maximum number of sessions allowed on the host pool.

Use the detailed diagnosis of the Total application groups measure to know which application groups are managed by the host pool, and how many applications / desktops each group contains.
