Description
The Test-SqlAvailabilityGroup cmdlet evaluates the health of an availability group.
This cmdlet evaluates SQL Server policy-based management policies.
To run this cmdlet, you must have CONNECT
, VIEW SERVER STATE
, and VIEW ANY DEFINITION
user rights.
Module requirements: version 21+ on PowerShell 5.1; version 22+ on PowerShell 7.x.
Examples
Example 1: Evaluate the health of an availability group
PS C:\> Test-SqlAvailabilityGroup -Path "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups\MainAG"
This command evaluates the health of the availability group named MainAG
.
The command returns a summary.
Example 2: Evaluate the health of all availability group
PS C:\> Get-ChildItem "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups" | Test-SqlAvailabilityGroup
This command gets all availability groups that have availability replicas in the specified location in the SQLSERVER: provider. The command passes them to the current cmdlet by using the pipeline operator. That cmdlet evaluates the health of each availability group.
Example 3: Display results for each policy of an availability group
PS C:\> Test-SqlAvailabilityGroup -Path "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups\MainAG" -ShowPolicyDetails
This command evaluates the health of the availability group named MainAG
.
This command specifies the ShowPolicyDetails parameter.
Therefore, it displays the evaluation results for each policy-based management policy that ran.
Example 4: Display results for userdefined policies of an availability group
PS C:\> Test-SqlAvailabilityGroup -Path "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups\MainAG" -AllowUserPolicies
This command evaluates the health of the availability group named MainAG
.
The command includes user-defined policies in this evaluation.
Example 5: Get groups that have an error state
PS C:\> Get-ChildItem "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups" | Test-SqlAvailabilityGroup | Where-Object { $_.HealthState -eq "Error" }
This command gets all availability groups that have availability replicas in the specified location in the SQLSERVER: provider. The command passes them to the current cmdlet by using the pipeline operator. That cmdlet evaluates the health of each availability group. The command passes those results to the Where-Object cmdlet, which returns results based on the HealthState property.
Parameters
-AccessToken
The access token used to authenticate to SQL Server, as an alternative to user/password or Windows Authentication.
This can be used, for example, to connect to SQL Azure DB
and SQL Azure Managed Instance
using a Service Principal
or a Managed Identity
(see references at the bottom of this page)
In common scenarios, this parameter is obtained with something like (Get-AzAccessToken -ResourceUrl https://database.windows.net).Token
(requires the Az.Accounts module)
The type of the parameter can be either string
(clear text token) or SecureString
(encrypted token, as returned by newer version of the Get-AzAccessToken cmdlet.)
Type: | PSObject |
Position: | Named |

-AllowUserPolicies
Indicates that this cmdlet tests user policies found in the policy categories of Always On Availability Groups.
Type: | SwitchParameter |

-Encrypt
The encryption type to use when connecting to SQL Server.
This value maps to the Encrypt
property SqlConnectionEncryptOption
on the SqlConnection object of the Microsoft.Data.SqlClient driver.
In v22 of the module, the default is Optional
(for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.
This parameter is new in v22 of the module.
Type: | String |
Accepted values: | Mandatory, Optional, Strict |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-HostNameInCertificate
The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.
This parameter is new in v22 of the module.
Type: | String |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-InputObject
Specifies an array of availability group, as AvailabilityGroup objects. This cmdlet evaluates the health of the availability groups that this parameter specifies.
Type: | AvailabilityGroup[] |
Position: | 1 |
Default value: | None |
Required: | True |
Accept pipeline input: | True |
Accept wildcard characters: | False |
-NoRefresh
Indicates that will not refresh the objects specified by the Path or InputObject parameter.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-Path
Specifies the path of the availability group that this cmdlet evaluates. If you do not specify this parameter, this cmdlet uses current working location.
Type: | String[] |
Position: | 1 |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-ShowPolicyDetails
Indicates that this cmdlet displays the result of each policy evaluation that it performs. The cmdlet returns one object per policy evaluation. Each policy object includes the results of evaluation. This information includes whether the policy passed or not, the policy name, and policy category.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-TrustServerCertificate
Indicates whether the channel will be encrypted while bypassing walking the certificate chain to validate trust.
In v22 of the module, the default is $true
(for compatibility with v21). In v23+ of the module, the default value will be '$false', which may create a breaking change for existing scripts.
This parameter is new in v22 of the module.
