Table 145. LSASS drilldown

LSASS CPU Usage

The percentage of the CPU used by the LSASS process.

LSASS I/O Activity

How many bytes have been read from or written to the Active Directory database by the LSASS process. Read activity is shown in orange. Write activity is shown in blue.

The number of NTLM NT Lan Manager Authentications and Kerberos Authentications per second being handled by the currently connected domain controller. NTLM Authentications are shown in orange and Kerberos Authentications are shown in blue.

Directory Activity

The number of directory read and write operations per second occurring on this domain controller. Read activity is shown in orange, and write activity is shown in blue.

FSMO Roles drilldown

The Flexible Single-Master Operation (FSMO) Roles drilldown indicates which domain controller owns each FSMO role. It also indicates which domain controller is the Global Catalog (GC) server.

NOTE: By default, the FSMO Roles drilldown collects only the FSMO roles for the domain where the domain controller is located. Select Collect FSMO role holders from other domains to collect all FSMO roles in the forest. If selected, this check box is applied to all current connections as well as new future connections.

The FSMO Roles drilldown displays the following information.

FSMO Role

The five main roles a server can fulfill. These include Domain Naming Master, Schema Master, Infrastructure Master, PDC Emulator, and RID Server.

Global Catalog and Intersite Topology Generator are not FSMO roles; they are listed here as extra information.

Domain Controller

The network name of the computer that fulfills the associated FSMO role.

Domain

The name of the domain to which the computer belongs.

Site
