Parameter	Type	What it controls
-Identity	ServerIdParameter	The Identity parameter specifies the Mailbox server that you want to test. You can use any value that uniquely identifies the server. For example:
-ActiveDirectoryTimeout	Int32	The ActiveDirectoryTimeout parameter specifies the time interval in seconds that's allowed for each directory service operation before the operation times out. The default value is 15 seconds.
-Confirm	SwitchParameter	The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on whether the cmdlet requires confirmation before proceeding.
-DatabaseAvailabilityGroup	DatabaseAvailabilityGroupIdParameter	The DatabaseAvailabilityGroup parameter specifies whether to test all servers in the specified DAG. You can use any value that uniquely identifies the DAG. For example:
-DomainController	Fqdn	The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name...
-MonitoringContext	Boolean	The MonitoringContext parameter specifies whether to include the associated monitoring events and performance counters in the results. Valid values are:
-OutputObjects	SwitchParameter	The OutputObjects switch specifies whether to output an array of information regarding failures. You don't need to specify a value with this switch.
-TransientEventSuppressionWindow	UInt32	The TransientEventSuppressionWindow parameter specifies the number of minutes that the queue lengths can be exceeded before the queue length tests are considered to have failed. This parameter is used to reduce the...
