Replication Health (AD_AD_REPLICATION)
This application class monitors the performance of Active Directory replication for the local server. The single instance is named Replication.
The Replication Health monitor type in BMC ProactiveNet Performance Management is referred as the AD_AD_REPLICATION application class in BMC PATROL.
To access the AD_AD_REPLICATION application class, double-click the Active Directory Server icon.
Application class or Monitor type details
Did you know?
Monitor types in the TrueSight console and Central Monitoring Administration are known as application classes in the PATROL consoles.
Attributes in Central Monitoring Administration are known as parameters in the PATROL consoles.
Parameter Reference Database (PRD)
The attribute information is also available in downloadable format in the
The PRD contains reports of the parameters available from the KMs and solutions in the extensive Knowledge Module (KM) library.
You can access these reports in CSV, PDF, or HTML format.
The following attributes are available for this monitor type:
|Name||Description||Unit||Default Performance Key Indicator (KPI)|
Duplicate Object Error (AdRpDuplicateObject)
|Monitors directory replication to report duplicate object errors.|
This parameter monitors the warning Event ID 1083 in the directory service event log. The event source is NTDS replication.
Active Directory is unable to update an object in replication if a duplicate object exists. This problem could be caused by lost objects, lingering objects, or object name conflicts.
|Enabled Inbound Connection Count (AdRpInboundConnectionCount)||Reports the number of inbound replication connections. The number should not exceed the user-defined threshold.||Number of connections||No|
|Failed Synchronization Requests (AdRpFailedSyncRequests)||Reports the number of unsuccessful synchronization requests processed since the last collection cycle.||Number of requests||Yes|
|Inbound Byte Rate (AdRpInboundByteRate)||Reports the rate at which bytes of data are arriving at the Active Directory server.||Bytes per second||No|
|Inbound Object Rate (AdRpInboundObjectRate)||Reports the rate at which objects are arriving that need to be added to the current Active Directory server.||Objects per second||No|
Inbound Property Rate (AdRpInboundPropertyRate)
|Reports the rate at which property changes are arriving at the Active Directory server.||Properties per second||No|
|Inbound Value Rate (AdRpInboundValueRate)||Reports the rate at which values are arriving at the Active Directory server.||Values per second||No|
|Lingering Object Error (AdRpLingeringObject)||Monitors for the occurrence of lingering objects.|
This parameter monitors the error Event ID 1388 in the directory service event log. The event source is NTDS replicator.
When a domain controller is reconnected to the replication topology, any objects that were deleted from Active Directory while the domain controller was offline can remain on the domain controller as lingering objects.
|Outbound Byte Rate (AdRpOutboundByteRate)|
Reports the rate at which bytes of data are leaving the Active Directory server.
|Bytes per second||No|
|Outbound Object Rate (AdRpOutboundObjectRate)||Reports the rate at which objects that need to be added to other Active Directory servers have left the current Active Directory server since the last collection cycle.||Objects per second||No|
|Outbound Property Rate (AdRpOutboundPropertyRate)||Reports the rate at which property changes have left the Active Directory server since the last collection cycle.||Properties per second||No|
Outbound Value Rate (AdRpOutboundValueRate)
|Reports the rate that values are leaving the Active Directory server.||Values per second||No|
|Pending Synchronization Requests (AdRpPendingSyncRepl)||Reports the number of directory synchronization requests that are queued for this server but have not yet been processed.||Number of requests||No|
|Replication Failed (AdRpFailed)||Reports replication failures. This parameter monitors the warning Event ID 1265 in the directory service event log. The event source is NTDS Knowledge Consistency Checker (KCC).||No|
|Service Principal Name Mismatch (AdRpSpnMismatch)|
Reports errors that occur when the NT Directory Service (NTDS) received a failure while trying to perform an authenticated RPC call to another Domain Controller due to a service principal name (SPN) mismatch.
This parameter monitors the error Event ID 1645 in the directory service event log. The event source is NTDS replication. This failure can occur if the desired SPN is not registered on the target server.
|Successful Synchronization Requests (AdRpSuccessSyncRequests)||Reports the number of synchronization requests that were successfully processed since the last collection cycle.||Number of requests||No|
|Synchronization Requests (AdRpSyncRequests)||Reports the number of synchronization requests processed since the last collection cycle.||Number of requests||No|
|Topology Mismatch (AdRpTopologyMismatch)|
Reports a topology mismatch, which occurs when replication configuration information in Active Directory Sites and Services does not reflect the physical topology of the network.
This parameter monitors the error Event ID 1311 in the directory service event log. The event source is NTDS Knowledge Consistency Checker (KCC).
