DFSRS private bytes

Indicates that the virtual memory allocated to the Distributed File System Replication (DFSR) service is too high.

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

Tests the DFSRS private bytes performance counter on the domain controller for the DFSR service to see if the value in the performance counter goes above the configured threshold for a period exceeding the configured duration.

Review the system configuration and tune the environment to optimize DFSRS performance as described in these references:

DFSRS RDC is not enabled

Indicates that any of Distributed File System Replication (DFSR) connections have the Remote Differential Compression (RDC) option disabled.

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

Remote Differential Compression (RDC) only updates changes to files, which is useful when replicating across a wide area network.

Enable Remote Differential Compression.

DFSRS sharing violation

Indicates that a sharing violation exists for a period greater than or equal to the specified threshold.

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

The Active Directory Health Analyzer agent monitors the DFRS debug log for reports of sharing violations. If the sharing violation exists for a period exceeding the configured duration, the agent sets this alert condition.

One possibility for the sharing violation is that other sources may have opened the file to be replicated on the target machine.

Another possibility for a sharing violation is that other sources have open handles to the file to be replicated. Typically, programs that can instigate sharing violations are:

FRS Encounters "ERROR_SHARING_VIOLATION" Errors When It Tries to Replicate Data That Is Still in Use

DFSRS staged file age

Indicates that the age of files in the Distributed File System Replication (DFSR) staging folder is greater than or equal to the specified threshold.

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: When monitored locally and remotely, only domain user privilege is required and the user must be a part of the Performance Logs user group.

This situation could be caused by the following factors:

If a D2 was not performed on a downstream partner, look for failure indicators at either the upstream or downstream partners. If you cannot find failure indicators, re-examine the schedule and network bandwidth on this connection to ensure that enough replication time is scheduled to allow the data to replicate.
