Active Directory Performance
The System Monitor object NTDS is useful for monitoring domain controller performance. The below counters in the Performance Monitor tool show replication traffic information.
- DRA Inbound Bytes Total/sec
- DRA Outbound Bytes Total/sec
- DRA Inbound Bytes Not Compressed - Replicated uncompressed bytes that are probably from a Directory Services Agent (another controller sending data) in the same site.
- DRA Inbound Bytes Compressed (Before Compression) - Replicated bytes received (as though in uncompressed form).
- DRA Inbound Bytes Not Compressed (After Compression) - Replicated bytes received (as in compressed form).
- DRA Inbound Bytes Total The sum of the DRA Inbound Bytes Not Compressed plus the DRA Inbound Bytes Not Compressed (After Compression).
- DRA Outbound Bytes Not Compressed - Replicated uncompressed bytes that are being sent to another domain controller in the same site.
Active Directory Replication Monitor
The Active Directory Replication Monitor is used to monitor Active Directory database replication between domain controllers.
