DFS service is not running

Indicates the Distributed File System (DFS) Namespace Service is stopped.

Category: Windows Services
Name: DFS Namespace Service
Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
Required permissions: When monitored locally, only domain user privilege is required. When monitored remotely, domain administrator privilege is required.

The Directory Analyzer agent periodically checks to ensure the DFS Namespace Service is running.

Use the Services MCC snap-in or another SCP application to restart the DFS Namespace Service.

DFSR conflict area disk space

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.

If the ConflictAndDeleted folder runs out of space, DFS Replication removes older conflicting or deleted files to free up disk space, which might temporarily decrease replication performance.

If a staging folder quota is configured to be too small, DFS Replication might consume additional CPU and disk resources to regenerate the staged files. Replication might also slow down because the lack of staging space can limit the number of concurrent transfers with partners. Increasing the size of the staging folder and the ConflictAndDeleted folder can increase replication performance and the number of recoverable conflicting and deleted files.

Delete files from the ConflictAndDeleted folder or increase the quota of the ConflictandDeleted folder for the appropriate replicated folder(s).

DFSR conflict files generated

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.
Description

Monitoring this performance counter enables administrators to keep track of the number of replication conflicts generated for replicated folders on the monitored computer. Monitoring the space utilization of the Conflict and Deleted area helps ensure that there is enough space to store replication conflicts and files deleted from replicated folders on the monitored computer. You can view a log of conflict files and their original file names by viewing the ConflictandDeletedManifest.xml file in the DfsrPrivate folder.

Frequent conflicts indicate that files in a replicated folder are frequently being modified on multiple servers in a short period.

Resolution

In general, resolution of this alert condition involves deciding whether a conflict object contains useful information, moving that information into a different directory object, and then deleting the object. Determining whether the conflict object has any useful information is up to you, the administrator.

DFSRS CPU load

Indicates that the CPU for the Distributed File System Replication (DFSR) service is too busy.

Data collector
Category: Performance Counters
Name: DFSRS % processor time
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.
Description

The Active Administrator Foundation Service (AFS) periodically checks the CPU utilization by the DFSR service. If the utilization is above the configured threshold, an alert is generated.

Resolution

Wait for a while to see if the error clears itself. For example, a high CPU utilization that occurs during an initial replication is transitory in nature.

Review the system configuration and tune the environment to optimize DFSRS performance.
