Identify and diagnose issues in Azure Virtual Desktop (classic)
Important
This content applies to Azure Virtual Desktop (classic), which doesn't support Azure Resource Manager Azure Virtual Desktop objects. If you're trying to manage Azure Resource Manager Azure Virtual Desktop objects, see this article.
Azure Virtual Desktop offers a diagnostics feature that allows the administrator to identify issues through a single interface. The Azure Virtual Desktop roles log a diagnostic activity whenever a user interacts with the system. Each log contains relevant information such as the Azure Virtual Desktop roles involved in the transaction, error messages, tenant information, and user information. Diagnostic activities are created by both end-user and administrative actions, and can be categorized into three main buckets:
- Feed subscription activities: the end-user triggers these activities whenever they try to connect to their feed through Microsoft Remote Desktop applications.
- Connection activities: the end-user triggers these activities whenever they try to connect to a desktop or RemoteApp through Microsoft Remote Desktop applications.
- Management activities: the administrator triggers these activities whenever they perform management operations on the system, such as creating host pools, assigning users to application groups, and creating role assignments.
Connections that don't reach Azure Virtual Desktop won't show up in diagnostics results because the diagnostics role service itself is part of Azure Virtual Desktop. Azure Virtual Desktop connection issues can happen when the end-user is experiencing network connectivity issues.
To get started, download and import the Azure Virtual Desktop PowerShell module to use in your PowerShell session if you haven't already. After that, run the following cmdlet to sign in to your account:
Add-RdsAccount -DeploymentUrl "https://rdbroker.wvd.microsoft.com"
Diagnose issues with PowerShell
Azure Virtual Desktop Diagnostics uses just one PowerShell cmdlet but contains many optional parameters to help narrow down and isolate issues. The following sections list the cmdlets you can run to diagnose issues. Most filters can be applied together. Values listed in brackets, such as <tenantName>, should be replaced with the values that apply to your situation.
Important
The diagnostics feature is for single-user troubleshooting. All queries using PowerShell must include either the -UserName or -ActivityID parameters. For monitoring capabilities, use Log Analytics. See Use Log Analytics for the diagnostics feature for more information about how to send diagnostics data to your workspace.
Filter diagnostic activities by user
The -UserName parameter returns a list of diagnostic activities initiated by the specified user, as shown in the following example cmdlet.
Get-RdsDiagnosticActivities -TenantName <tenantName> -UserName <UserUPN>
The -UserName parameter can also be combined with other optional filtering parameters.
Filter diagnostic activities by time
You can filter the returned diagnostic activity list with the -StartTime and -EndTime parameters. The -StartTime parameter will return a diagnostic activity list starting from a specific date, as shown in the following example.
Get-RdsDiagnosticActivities -TenantName <tenantName> -UserName <UserUPN> -StartTime "08/01/2018"
The -EndTime parameter can be added to a cmdlet with the -StartTime parameter to specify a specific period of time you want to receive results for. The following example cmdlet will return a list of diagnostic activities from between August 1 and August 10.
Get-RdsDiagnosticActivities -TenantName <tenantName> -UserName <UserUPN> -StartTime "08/01/2018" -EndTime "08/10/2018"
The -StartTime and -EndTime parameters can also be combined with other optional filtering parameters.
Filter diagnostic activities by activity type
You can also filter diagnostic activities by activity type with the -ActivityType parameter. The following cmdlet will return a list of end-user connections:
Get-RdsDiagnosticActivities -TenantName <tenantName> -UserName <UserUPN> -ActivityType Connection
The following cmdlet will return a list of administrator management tasks:
Get-RdsDiagnosticActivities -TenantName <tenantName> -ActivityType Management
The Get-RdsDiagnosticActivities cmdlet doesn't currently support specifying Feed as the ActivityType.
Filter diagnostic activities by outcome
You can filter the returned diagnostic activity list by outcome with the -Outcome parameter. The following example cmdlet will return a list of successful diagnostic activities.
Get-RdsDiagnosticActivities -TenantName <tenantName> -UserName <UserUPN> -Outcome Success
The following example cmdlet will return a list of failed diagnostic activities.
Get-RdsDiagnosticActivities -TenantName <tenantName> -Outcome Failure
The -Outcome parameter can also be combined with other optional filtering parameters.
Retrieve a specific diagnostic activity by activity ID
The -ActivityId parameter returns a specific diagnostic activity if it exists, as shown in the following example cmdlet.
Get-RdsDiagnosticActivities -TenantName <tenantName> -ActivityId <ActivityIdGuid>
View error messages for a failed activity by activity ID
To view the error messages for a failed activity, you must run the cmdlet with the -Detailed parameter. You can view the list of errors by running the Select-Object cmdlet.
Get-RdsDiagnosticActivities -TenantName <tenantname> -ActivityId <ActivityGuid> -Detailed | Select-Object -ExpandProperty Errors
Retrieve detailed diagnostic activities
The -Detailed parameter provides additional details for each diagnostic activity returned. The format for each activity varies depending on its activity type. The -Detailed parameter can be added to any Get-RdsDiagnosticActivities query, as shown in the following example.
Get-RdsDiagnosticActivities -TenantName <tenantName> -ActivityId <ActivityGuid> -Detailed
Common error scenarios
Error scenarios are categorized in internal to the service and external to Azure Virtual Desktop.
- Internal Issue: specifies scenarios that can't be mitigated by the tenant administrator and need to be resolved as a support issue. When providing feedback through the Azure Virtual Desktop Tech Community, include the activity ID and approximate time frame of when the issue occurred.
- External Issue: relate to scenarios which can be mitigated by the system administrator. These are external to Azure Virtual Desktop.
The following table lists common errors your admins might run into.
Note
This list includes most common errors and is updated on a regular cadence. To ensure you have the most up-to-date information, be sure to check back on this article at least once a month.
