LSASS components

To see a definition, click the component to open a help box. From the help box, you can open a drilldown to view the associated statistics. See Using drilldowns.

Table 127. LSASS Components

CPU Usage

The total amount of CPU used by the LSASS process. This component opens the LSASS drilldown.

Memory Usage

The total amount of physical memory (RAM) available and the total amount used by the LSASS process. This component opens the All Processes tab on the Performance drilldown.

Replication Queue (DRA)

The number of directory synchronizations queued for this server but not yet processed. This component opens the Replication Queues drilldown.

File Replication components

To see a definition, click the component to open a help box. From the help box, you can open a drilldown to view the associated statistics. See Using drilldowns.

CPU Usage

The total amount of CPU used by the NTFRS or DFSR process (depending on the type of replication service used). If you are using NTFRS and are migrating to DFSR file replication, this counter shows CPU usage for both NTFRS and DFSR services.

Memory Usage

The total amount of physical memory used by the NTFRS or DFSR process (depending on the type of replication service used). If you are using NTFRS and are migrating to DFSR file replication, this counter shows CPU usage for both NTFRS and DFSR services.

Replication Queue

The number of changes to files detected on this domain controller that have not yet been processed for replication. This component opens the Queues tab on the Replication drilldown.

AD Store components

To see a definition, click the component to open a help box. From the help box, you can open a drilldown to view the associated statistics. See Using drilldowns.

Database Size

The total size in megabytes of the file that stores Active Directory®. This file represents all of the data in the Active Directory and will grow as new objects are added.

Free Space

Total drive space available.

Total Space

The total drive space in use where Active Directory is stored.

Objects Applied/Second

The rate at which objects are being applied to the Active Directory database. This component opens the Replication drilldown.

Remaining Objects

The number of object updates remaining in the current replication update packet that have not yet been applied on the local domain controller. This component opens the Replication drilldown.

Active Directory components

The following table describes the Active Directory® components:

Replication Links

The number of active replication links for the target domain controller. This component opens the Directory Partners tab on the Replication drilldown.

DNS Entries

Shows whether or not the domain controller has registered the proper DNS entries with its DNS server. The component is running the DNS check from the computer where the Diagnostic Console is running on and not the domain controller to which it is connected. This component opens the DNS drilldown.

Schema Mismatches

The number of replication errors that have occurred as a result of a schema mismatch since the last refresh of the Diagnostic Console.

DRA Errors

The number of replication errors that have occurred since the last refresh of the Diagnostic Console.
