Active Directory replication monitoring tools

The Active Directory database is replicated between domain controllers. Only the changes are replicated, once a domain controller has been established. Active Directory uses a multimaster model which means changes can be made on any controller and the changes are sent to all other controllers.

The replication path in Active Directory forms a ring which adds reliability to the replication. I am sure all of us agree – this is important and we should check and monitor health of Active Directoryand replication among our AD servers.

For those Administrators who do not want to spend time to have fun with command line tools – you can use last year released GUI tool – Active Directory Replication Status Tool – aka ADREPLSTATUS.

The Active Directory Replication Status Tool (ADREPLSTATUS) analyzes the replication status for domain controllers in an Active Directory domain or forest.

For those of us with more experience we can use simply built in tools or PowerShell:

Show AD Replication with output to Grid-View

 repadmin /showrepl * /csv | ConvertFrom-Csv | Out-GridView

Show AD Replication partner and out-put into Grid-View

Get-ADReplicationPartnerMetadata -Target * -Partition * | Select-Object Server,Partition,Partner,ConsecutiveReplicationFailures,LastReplicationSuccess,LastRepicationResult | Out-GridView

Very nice PowerShell Script with output to HTML => Script Center
Show AD Replication and print details for each replication link

repadmin /showrepl *

Show AD Replication Errors only

repadmin /showrepl * /csv | ConvertFrom-Csv | ?{$_.'Number Of Failures'}

As you can see there is many ways to get the good details on your Active Directory replication.
