Daily Monitoring Tasks

Table 1.5 Daily Tasks and Their Importance

Tasks Importance

Verify that all domain controllers are

communicating with the central monitoringconsole or collector.

Communication failure between the domaincontroller and the monitoring infrastructure

prevents you from receiving alerts so you can

examine and resolve them.

View and examine all new alerts on each domaincontroller, resolving them in a timely fashion.

This precaution helps you avoid serviceoutages.

Resolve alerts indicating the following services

are not running: FRS, Net Logon, KDC,

W32Time, ISMSERV. MOM reports these as

Active Directory Essential Services.

Active Directory depends on these services.They must be running on every domain

controller.

Resolve alerts indicating SYSVOL is not shared. Active Directory cannot apply Group Policyunless SYSVOL is shared.

Resolve alerts indicating that the domain

controller is not advertising itself.

Domain controllers must register DNS records

to be able to respond to LDAP and otherservice requests.

Resolve alerts indicating time synchronization

problems.

The Kerberos authentication protocol requires

that time be synchronized between all domaincontrollers and clients that use it.

Resolve all other alerts in order of severity. If

alerts are given error, warning, and information

status similar to the event log, resolve alertsmarked error first.

The highest priority alerts indicate the most

serious risk to your service level..

Weekly Monitoring Tasks

Table 1.6 Weekly Tasks and Their Importance

Tasks Importance

Review the Time Synchronization Report todetect intermittent problems and resolve time-

related alerts.

The Kerberos authentication protocol requiresthat time be synchronized between all domain

controllers and clients that use it.Review the Authentication Report to help

resolve problems generated by computeraccounts with expired passwords.

Expired passwords must be reset to allow the

computers to authenticate and participate in thedomain.

Review the Duplicate Service Principal Name

Report to list all security principals that have aservice principal name conflict.

User or computer accounts cannot be

authenticated or log on if they share an SPNwith another account.

Review a report of the top alerts generated by

the Active Directory monitoring indicators and

resolve those items that occur most frequently.

Report shows alerts that occur most often.Focusing on the top alert generatorssignificantly reduces the number of alerts seen

by the operator.

Review the report that lists all trust relationships

in the forest and check for obsolete, unintended,or broken trusts.

Authentication between domains or forests

requires trust relationships.

Monthly Monitoring Tasks

Table 1.7 Monthly Tasks and Their Importance

Tasks Importance

Verify that all domain controllers are running with

the same service pack and hot fix patches.

Potential issues can arise if distributed

services are running with different versionsof software.

Review all Active Directory reports and adjustthresholds as needed. Examine each report and

determine which reports, data, and alerts are

important for your environment and service level

agreement.

Examining the data that is relevant to your

environment allows you to determine thethresholds that trigger the alerts to your

service level delivery.

Review the Replication Monitoring Report to

verify that replication throughout the forest occurs

within acceptable limits

Timely replication helps assure that youmeet your service level agreements.

Review the Active Directory response time reports.

Services must respond quickly for the

system to function properly and applicationssuch as e-mail to work properly.

Review the domain controller disk space reports.

The drives containing the Active Directory

database and log files must have sufficientfree space to accommodate growth and

routine processing.

Review all performance-related reports. Thesereports are called Health Monitoring reports in

MOM.

These reports can help you determine thebaseline for your environment and adjust

thresholds.

Review all performance-related reports for

capacity planning purposes to ensure that you haveenough capacity for current and expected growth.These reports are called Health Monitoring reports

in MOM.

These reports help you track growth trendsin your environment and plan for futurehardware and software needs.

Adjust performance counter thresholds or disablerules that are not applicable to your environment or

that generate irrelevant alerts.

Monitoring indicators must be adjusted tosuit your environment. The goal is to

provide alerts that are concise, highly

relevant, and lead an operator to resolve the
