MICROSOFT OPERATIONS MANAGER
Microsoft Operations Manager is the most recent of the optional management suites offered to support Windows 2000 and Windows 2003 servers. The focus of MOM is to provide event and performance monitoring. This product is particularly useful for administrators charged with monitoring Active Directory, Exchange Server, and SQL Server. The relatively open API has also permitted third parties to develop add-ons for cross-platform monitoring from within MOM. The primary architectural features touted by Microsoft include:
Enterprise-class scalability.
MOM uses a three-tier architecture designed to handle hundreds of millions of fully redundant and load-balanced events per day.
Intelligent agents.
MOM's agents are based on the rule sets defined by the administrators at a central console. The local agents filter, aggregate, and consolidate event streams. They will also trigger local actions.
Automated agents and rule deployment.
MOM monitors Active Directory and Windows NT domains to automatically detect and report new servers, applications, and services. MOM loads only appropriate rule sets. Deployment of agents and rule sets can then be set to occur automatically. MOM updates local rule sets as applications are installed and removed.
Interoperability.
The integration of Windows Management Instrumentation (WMI) and MOM allows the intake of a wide range of events and performance data from Windows Server 2003, Windows 2000, or Windows NT systems. Additionally, MOM can monitor SNMP event data (traps) for any specified devices. These SNMP trap messages can be generated as part of any defined rule and then delivered to a third-party SNMP management products like HP OpenView. Through the Syslog protocol, MOM can even monitor live events from UNIX systems and many network devices.
NOTEIt is important that administrators understand the relationship of the Microsoft optional management tools. Application Center 2000 performs the classic role of managing software applications and licenses. It is targeted at enterprises that manage Web-based and component-based applications. As described in the previous section, SMS provides change and configuration management. By contrast, MOM delivers operational management functions for servers and applications. These products are designed to work in tandem and are generally a good investment for medium to large enterprises.
Microsoft Operations Manager Features
MOM uses the Microsoft Management Console by default to provide a consistent administrative interface. Through the MMC, status and configuration nodes should be snapped in along with other related management tools and applications. This allows administrators to move through the hierarchical tree to access events, rules, reports, and configuration activities. Additionally, MOM's MMC snap-in supports context-sensitive tasks directly from the Alert box or event being viewed. This means that tasks such as Terminal Services sessions or command-line functions can be launched directly from MOM.
DISTRIBUTE EVENT MANAGEMENT
MOM captures system and applications events from Windows-based systems distributed throughout the enterprise and aggregates them into a central event repository. This allows the administrator to consolidate events so that a view of server and service availability can be reviewed easily. In addition to event summaries, a detailed event stream can be obtained for specific troubleshooting activities.
ADMINISTRATIVE DEFINED RULES MANAGEMENT
Once established by the administrator, MOM reacts automatically to incoming message streams. The system can be configured to respond with a predefined action to a specific fault scenario. Alternatively, MOM will consolidate messages so the analysis can be made of broader based events. MOM's rules can be made to react intelligently to anticipated event patterns. These patterns trigger actions including sending alerts to the administrator. Rules may be linked to an event sequence of the Microsoft Knowledge Base articles, thereby providing guidance on probable causes and approved responses to a specific problem.
ALERT MANAGEMENT
Any MOM rule can be configured to generate specific alerts that are associated with severity levels. An alert can represent a single event or multiple events from many sources. One of the nicer features is the ability to trace the history of a given alert. The events can be associated and then used to consult related Knowledge Base articles. Functionally, alerts can trigger e-mail messages, pages, and Simple Network Management Protocol traps. Scripts can even be used to notify administrators of emerging problems.
PERFORMANCE MONITORING
MOM monitors key performance thresholds. Administrators customize and add rules that allow them to monitor trends of system and application performance. These reports are useful for historical reporting and capacity planning. Local and aggregated thresholds are also used to generate alerts and actions. As system changes occur or application behavior demands intervention, the appropriate alerts are broadcast.
GRAPHICAL REPORTING TOOLS AND WEB REPORTING
MOM provides access to a broad range of preconfigured reports and charts. This allows administrators to review at a glance the status of systems and services on the network. By quickly reviewing clean graphical output, the administrator can plan changes to the infrastructure. Alternatively, MOM can generate HTML-based snapshots of all generated reports. Instead of using MMC, these reports can be exported to a Web server to provide access from Web browsers.
OPTIONAL MANAGEMENT PACKS
To reduce an administrator's burden, Microsoft offers management packs that consist of preconfigured MOM rule sets and Knowledge Base articles. Each pack provides rules for a specific range of applications or services. Developed and refined by experts, the management packs provide an off-the-shelf solution plus a strong foundation for advanced administrators to customize and extend basic MOM functionality.Most management packs are optional, but several are included with MOM including one that enables management of critical Windows services such as Active Directory service and Internet Information Services. Additional management packs are available from Microsoft and third-party vendors. Among the products and services optionally supported are BackOffice and Windows Server 2003 enterprise applications, plus a wide range of enterprise applications.
