AVD Feeds By Workspaces Test
Users can connect to Azure Virtual Desktop resources using any type of client that Azure provides/supports. This can be:
-
A web client that lets you access AVD resources from a web browser
-
A Windows Desktop client that let you access AVD resources from devices running Windows operating systems
-
An Android / Mac OS / iOS client using which you can access virtual desktops from devices running the corresponding operating systems;
-
A Microsoft Store client that allows users on Windows 10 devices access to Azure virtual desktops;
-
A host of partner-approved clients using for 'thin client devices'
After installing a client on a connecting device, you need to configure which AVD resources that client has access to. One of the ways in which this can be configured is by subscribing to a workspace. You can subscribe to a workspace by specifying the workspace URL, so that the client has access to all the RemoteApp / Desktop application groups contained within that workspace.
When the client requests access to an app/desktop, they will have to provide this workspace URL as the Feed URL at the Azure control panel and retrieve the RDP file required to launch that app/desktop. If the files and icons required for launching an app/desktop cannot be retrieved, then the target app/desktop cannot be launched. This can scar the user experience with the AVD service. To avoid this, administrators should keep an eye on AVD feeds used by clients to launch desktops in AVD host pools, instantly capture failed attempts at retrieving RDP files/icons for launching, investigate the reasons for the failures, and rapidly eliminate them. This is where the AVD Feeds by Workspaces test helps!
This test monitors the feeds using which clients access session hosts/desktops in every AVD host pool. In the process, the test instantly alerts administrators to failed attempts at retrieving RDP files and/or icons. This way, the test warns administrators of probable issues in accessing/launching desktops, and also points you to host pools where such issues may be occurring frequently.
Note:
Typically, to consolidate log entries, correlate log data, and perform complex analysis, a host pool's logs are often sent to one/more Log Analytics Workspaces. This test reports valid metrics on workspace feeds by reading data from these Log Analytics Workspaces only. If the host pool's logs are not sent to any Log Analytics Workspace, then this test will only report the value 0 for most of its measures. To avoid this, before configuring this test, make sure that the host pool's logs are configured to be sent to at least one Log Analytics Workspace. Follow the steps discussed in Configuring the Host Pool Logs to be Sent to a Log Analytics Workspace to achieve this.
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
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:
|
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 a Microsoft AVD Broker Using Azure ARM REST API |
Client ID and Client Password |
To collect the required metrics, the eG agent requires an Access token in the form of an Application ID and the client secret value. If a Microsoft Azure Subscription component or a Microsoft Azure Active Directory component is already being monitored, then an Application would have already been created for monitoring purposes. The Application ID and Client Secret of such an application can be specified here. However, if no such application exists, then you will have to create one for monitoring the AVD broker. To know how to create such an application and determine its Application ID and Client Secret, refer to Configuring the eG Agent to Monitor a Microsoft AVD Broker Using Azure ARM REST API. 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. |
Log Analytics Workspace Name |
Typically, to consolidate log entries, correlate log data, and perform complex analysis, a host pool's logs are often sent to one/more Log Analytics Workspaces. By default, the Log Analytics Workspace Name parameter is set to All. This indicates that the test reads log data from all Log Analytics Workspaces configured for the target subscription, by default. However, if you want the test to use only those Log Analytics Workspaces to which a host pool's logs are sent, then provide the names of these workspaces here as a comma-separated list. To determine the names of the workspaces, do the following:
|
Show Total Feeds DD |
By default, this test does not report detailed diagnostics for the Total RDP feeds and Total icon feeds measures. Accordingly, this parameter is set to No by default. Typically, in large AVD roll-outs, these two measures can report numerous records as part of detailed diagnostics. In such environments therefore, the detailed statistics for these measures can consume excessive space in the eG database. This default setting conserves valuable database space by ensuring that the test does not collect detailed metrics for the Total RDP feeds and Total icon feeds measures. However, If you have a well-sized and well-tuned eG database, you can configure the test to capture detailed metrics for these two measures. To achieve this, set 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 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, 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:
|
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Total RDP feeds |
Indicates the total number of RDP files that the client attempted to retrieve when accessing the session hosts in this host pool during the last measurement period. |
Number |
Use the detailed diagnosis of this measure to know which user connecting from which client IP addresses attempted to retrieve how many RDP files. |
Failed RDP feeds |
Indicates the total number of RDP files that the client failed to retrieve when attempting to access the session hosts in this host pool during the last measurement period. |
Number |
Ideally, the value of this measure should be 0. If this measure reports a non-zero value, then use the detailed diagnosis of this measure to know the details of the users whose access requests failed because one/more RDP files could not be retrieved. |
Total icon feeds |
Indicates the total number of icon files (PNG, ICO) that the client attempted to retrieve when accessing the session hosts in this host pool during the last measurement period. |
Number |
Use the detailed diagnosis of this measure to know which user connecting from which client IP addresses attempted to retrieve how many icon files. |
Failed icon feeds |
Indicates the total number of icon files (PNG, ICO) that the client failed to retrieve when attempting to access the session hosts in this host pool during the last measurement period. |
Number |
Ideally, the value of this measure should be 0. If this measure reports a non-zero value, then use the detailed diagnosis of this measure to know the details of the users whose access requests failed because one/more icon files could not be retrieved. |
