Cloud error object properties.

Name	Type	Description
code	string	Error code
message	string	Error message indicating why the operation failed.

The type of identity that created the resource.

Name	Type	Description
Application	string
Key	string
ManagedIdentity	string
User	string

HealthCheckName

Represents the name of the health check operation performed.

Name	Type	Description
AppAttachHealthCheck	string	Verifies that the AppAttachService is healthy (there were no issues during package staging). The AppAttachService is used to enable the staging/registration (and eventual deregistration/destaging) of MSIX apps that have been set up by the tenant admin. This checks whether the component had any failures during package staging. Failures in staging will prevent some MSIX apps from working properly for the end user. If this check fails, it is non fatal and the machine still can service connections, main issue may be certain apps will not work for end-users.
DomainJoinedCheck	string	Verifies the SessionHost is joined to a domain. If this check fails is classified as fatal as no connection can succeed if the SessionHost is not joined to the domain.
DomainReachable	string	Verifies the domain the SessionHost is joined to is still reachable. If this check fails is classified as fatal as no connection can succeed if the domain the SessionHost is joined is not reachable at the time of connection.
DomainTrustCheck	string	Verifies the SessionHost is not experiencing domain trust issues that will prevent authentication on SessionHost at connection time when session is created. If this check fails is classified as fatal as no connection can succeed if we cannot reach the domain for authentication on the SessionHost.
FSLogixHealthCheck	string	Verifies the FSLogix service is up and running to make sure users' profiles are loaded in the session. If this check fails is classified as fatal as even if the connection can succeed, user experience is bad as the user profile cannot be loaded and user will get a temporary profile in the session.
MetaDataServiceCheck	string	Verifies the metadata service is accessible and return compute properties.
MonitoringAgentCheck	string	Verifies that the required Geneva agent is running. If this check fails, it is non fatal and the machine still can service connections, main issue may be that monitoring agent is missing or running (possibly) older version.
SupportedEncryptionCheck	string	Verifies the value of SecurityLayer registration key. If the value is 0 (SecurityLayer.RDP) this check fails with Error code = NativeMethodErrorCode.E_FAIL and is fatal. If the value is 1 (SecurityLayer.Negotiate) this check fails with Error code = NativeMethodErrorCode.ERROR_SUCCESS and is non fatal.
SxSStackListenerCheck	string	Verifies that the SxS stack is up and running so connections can succeed. If this check fails is classified as fatal as no connection can succeed if the SxS stack is not ready.
UrlsAccessibleCheck	string	Verifies that the required WVD service and Geneva URLs are reachable from the SessionHost. These URLs are: RdTokenUri, RdBrokerURI, RdDiagnosticsUri and storage blob URLs for agent monitoring (geneva). If this check fails, it is non fatal and the machine still can service connections, main issue may be that monitoring agent is unable to store warm path data (logs, operations ...).
WebRTCRedirectorCheck	string	Verifies whether the WebRTCRedirector component is healthy. The WebRTCRedirector component is used to optimize video and audio performance in Microsoft Teams. This checks whether the component is still running, and whether there is a higher version available. If this check fails, it is non fatal and the machine still can service connections, main issue may be the WebRTCRedirector component has to be restarted or updated.
