Monitoring Active Directory Health

This is part of the Microsoft Active Directory Management Pack Technical Reference guide
Active Directory Management Pack monitors Active Directory, and the external components related to Active Directory, to ensure that their ongoing behavior falls within the bounds of normal, healthy Active Directory behavior. The ADMP definitions for the health of Active Directory and its related component are contained in the more than 400 ready-to-run processing rules that are included with Active Directory Management Pack. After MOM and ADMP are installed, these rules begin to monitor Active Directory and related component behavior immediately and automatically, and they alert you whenever unexpected behavior occurs.
Processing Rules and Operating System Versions
Monitoring Active Directory Components
Monitoring External Components
Client-Side Monitoring
Microsoft Operations Manager 2000 can be used to monitor domain controllers running Windows 2000 Server and domain controllers running Windows Server 2003. Active Directory Management Pack includes processing rules that apply to both Windows 2000 Server and Windows Server 2003, as well as processing rules that apply only to one or the other. ADMP processing rules in rule groups that contain “(Shared)” in the name of the group apply to both operating systems. Processing rules in rule groups that do not contain “(Shared)” in their name, and that reside within the Active Directory Windows .NET (enabled) processing rule group, apply only to domain controllers running Windows Server 2003. Processing rules in rule groups that do not contain “(Shared)” in their name, and that reside within the Active Directory Windows 2000 (enabled) processing rule group, apply only to domain controllers running Windows 2000 Server. MOM applies the appropriate ADMP rules to the appropriate domain controllers automatically, based on the operating system running on each domain controller. No manual configuration is required.
Note: In the MOM console, ADMP refers to “Windows Server 2003” as “Windows .NET.”
The following sections provide an overview of the Active Directory Management Pack processing rules that are used to monitor each of the Active Directory components, as well as the external components on which Active Directory depends.
Note In addition to the processing rules that are listed in the tables in this section, Active Directory Management Pack includes processing rules that perform ADMP-specific functions. For example, ADMP includes several “Miscellaneous componentname error” processing rules that are designed to monitor for event numbers that are not generated by current operating system versions but may be introduced by future product updates and service packs. In addition, ADMP also includes several “Reportname report available” processing rules that are designed to notify administrators when data collected by ADMP is available for viewing.
Interfaces
This section describes Active Directory Management Pack monitoring of the Active Directory protocol interfaces, which are sometimes referred to as protocol heads.
LDAP and Global Catalog
The LDAP and global catalog protocol interfaces provide the mechanism for communicating with Active Directory, and they are also indicators of Active Directory health. By performing LDAP global catalog binds and searches against a domain controller, Active Directory Management Pack can take a basic measure of Active Directory health. The LDAP and global catalog response time requirements vary by directory-enabled applications, but they are generally on the order of one second.
In addition to monitoring for specific events, ADMP monitors the general responsiveness of the LDAP protocol interface with the AD General Response monitoring script. For more information about this script, see “Appendix A: Active Directory Management Pack Scripts.”
The following table lists the processing rules that ADMP uses to monitor the LDAP protocol interface, as well as the events, thresholds, and alert levels that are associated with those rules.

MAPI
No specific health measurements exist for the MAPI interface, and Active Directory Management Pack does not currently include any monitoring rules that are specific to MAPI.
Replication Subsystem
Replication is one of the most important processes in Active Directory; therefore, it is monitored regularly by Active Directory Management Pack. ADMP monitors replication with several monitoring scripts, including AD Replication Monitoring, AD Replication Partner Count, and AD Replication. For more information about these scripts, see “Appendix A: Active Directory Management Pack Scripts.”
In addition, ADMP monitors for specific replication-related events, and it collects replication performance data for several replication-related ADMP reports. The following table lists the processing rules that ADMP uses to monitor replication, as well as the events, thresholds, and alert levels that are associated with those rules.

DIT
Active Directory Management Pack contains processing rules for monitoring database and log files in the DIT and for monitoring the quantity of lost and found objects on a domain controller.
Database and Log Files
By default, Active Directory Management Pack monitors the Active Directory database files and log files every 15 minutes for file size, and it monitors free disk space on the hosting volume, using the AD Database and Log File script:
If the database file or log file grows between measurements by more than 20 percent, which represents a fixed percentage in ADMP that cannot be modified, ADMP generates a warning alert.
If the free space on the volume hosting the Active Directory database is not at least 500 megabytes (MB) or 20 percent of current database size, whichever is greater, ADMP generates an error alert.
If the free space on the volume hosting the Active Directory log files is not at least 200 MB or 5 percent of current database size, whichever is greater, ADMP generates an error alert.

Lost and Found Objects
On a domain controller, the Lost and Found container contains Active Directory objects that have been orphaned. Orphaned objects create administrative overhead, because administrators must manually determine what to do with them. The AD Lost and Found Object Count script in Active Directory Management Pack monitors the number of orphaned objects on a domain controller every two hours.
The script generates a warning alert if more than 10 objects exist in the Lost and Found container. The script generates an error alert if more than 100 objects exist in the Lost and Found container.

Operations Masters (FSMOs)
Much of the monitoring of the operations master roles (also known as flexible single master operations (FSMO)) in Active Directory Management Pack occurs in the AD Op Master Response script. By default, this script runs every five minutes to determine if the operations master role holders are responding, and it reports alerts at various levels, depending on whether the role holders are reachable and how quickly they respond.
ADMP also includes the AD Replication Partner Op Master Consistency script for operation master monitoring. This script runs every hour to determine if domain controller replication partners agree on the identity of the role holders, and it generates alerts if domain controllers disagree on the current role holders.

In addition to monitoring from the perspective of domain controllers, Active Directory Management Pack also monitors from the perspective of directory clients. The goal of client-side monitoring is to provide a client perspective on the health of Active Directory. ADMP implements client-side monitoring by using workstations or servers in strategic physical locations as “probes,” or ADMP agents. These monitoring agents perform scripted directory tasks that mimic common actions performed by typical directory clients. The directory service results that are experienced by the ADMP agents are reported through ADMP alerts and performance, just as they are with monitored domain controllers.
You determine which computers on your network to use for client-side monitoring by simply adding those computers to the Active Directory Client Side Monitoring computer group. It is recommended that you have a computer for client-side monitoring physically near each of your directory-enabled application servers.
Active Directory Management Pack includes the processing rules in the following table for monitoring Active Directory health from the perspective of the client, as well as the events, thresholds, and alert levels that are associated with those rules.
