Parameters

-Confirm: Prompts you for confirmation before running the cmdlet.
-CountFiles: Indicates that the cmdlet counts the number of files present in the replicated content folders. By default, the cmdlet does not count files, in order to save time while generating a report.
-DomainName: Specifies the NetBIOS name or fully qualified domain name (FQDN) for the Active Directory Domain Service (AD DS) domain that contains a replication group. If you do not specify this parameter, the cmdlet uses the current domain of the user.
-GroupName (required): Specifies an array of names of replication groups. If you do not specify this parameter, the cmdlet queries for all participating replication groups. You can use a comma separated list and the wildcard character (*).
-MemberComputerName: Specifies an array of DFS Replication members to analyze in comparison to a server specified by the *ReferenceComputerName* parameter. If you do not specify this parameter, the cmdlet includes all members of the replication group. You can specify multiple computer names, separated by commas, as well as wildcard characters (*).
-Path: Specifies the folder path for the report file. If you do not specify this parameter, the cmdlet uses the current working directory. The cmdlet names each report in the format Health-\-\-\ with HTML and XML extensions.
-ReferenceComputerName: Specifies the name of a reference computer in the replication group. The replication backlog from this server is compared to all other members specified in the *MemberComputerName* parameter. If you do not specify this parameter, the cmdlet uses the local computer.
-WhatIf: Shows what would happen if the cmdlet runs. The cmdlet is not run.
