说明
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.
示例
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 user-defined 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.
