DFSRS staging area disk space

Indicates that the amount of disk space allocated for staging files during replication is less 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.

If the File Replication Service (FRS) runs out of staging disk space, replication will stop. The size of the contents of the staging areas for all active replication sets are subtracted from the user controlled size.

A low disk space condition can be due to many different things. Some possibilities are: the size of the data to be replicated is larger than the staging area, there are too many replica sets active at once, or there are files destined for one or more out-bound partners that have not been connected for a while.

DFSRS USN records accepted

Detects that there is heavy file replication traffic.

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 DFSR USN records accepted performance counter on a domain controller to see if the value of this performance counter goes above the configured threshold for a period exceeding the configured duration.

Replication is triggered by entries to the NTFS update sequence number (USN) change journal. A high value on this counter, such as one every five seconds, indicates heavy replication traffic and may result in replication latency.

None.

DFSRS working set

Indicates that the working set allocated to the DFS Replication 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 working set 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:

Domain controller relative identifier (RID)

Indicates that the available pool of relative identifiers (RIDs) on the selected domain controller is less than or equal to the configured 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.

Tests the RID pool assigned to the domain controller to see if the number of RIDs available to the server goes below the threshold.

All security principals in the Windows® NT Security Architecture are assigned a unique security ID (SID). The SID is made up of a domain identifier and a RID. RIDs are sequential numbers issued by the domain each time a new security principal (for instance a user object) is created in that domain.

Because each domain controller can create security principals, Active Directory® breaks the available range of RIDs into allocation pools that it assigns to each domain controller. Active Directory assigns one domain controller in each domain to be responsible for allocating RID pools to all of the other domain controllers in the domain; this is the RID Operations Master. When a domain controller uses up its allocation, it requests a new range from the RID Operations Master.

If a domain controller has a problem contacting the RID Operations Master, the domain controller can actually use up its entire allocation of RIDs, and be unable to create new security principals, which can result in failures when adding new users, services, and domain controllers to the domain.
