This section is an introduction to the logical architecture of Microsoft Operations Manager (MOM) and the recommended network architecture for implementing MOM to monitor the Hosted Messaging and Collaboration infrastructure.
Microsoft Operations Manager is a 32-bit application designed for the Windows Server 2003 R2 operating system platform. To perform effective monitoring and management, MOM is based on the Microsoft distributed multi-tier architecture:
- Presentation - The presentation layer consists of the MOM Administrator Microsoft Management Console (MMC), the Web console, and MOM Reporting.
- Business logic - The business logic layer consists of agents, Consolidators, associated Agent Managers, and the Data Access Server (DAS). The DAS provides centralized database access and query logic, and communications between the interfaces in the presentation layer and the components in the data layer.
- Data - The various Windows Server 2003 R2 data sources and the repository database make up the data layer.
The following figure illustrates the Microsoft Operations Manager architecture.

Administrators access the information in MOM and configure their rules and policies using one of two Microsoft Management Consoles (MMC): Operations Console or Administrators Console. To view Alerts, a service provider uses the Operations Console in MOM 2005. To configure the monitoring system, a service provider uses the Administrators Console. These administrative utilities use the DAS as the intermediary to the Microsoft Operations Manager database, just like the Consolidator and agents. A Web interface for the Operations Console is available.
The architecture of MOM consists of product components and interfaces. Components provide functionality, and interfaces provide access to the collected data and configuration functionality.
MOM consists of the following components and interfaces:
A service that runs on each computer that you want to monitor. An agent captures information from a remote computer, applies processing rules to the collected information, and sends the processed information to a Consolidator.
|Data Access Server (DAS)|
A service that runs on a select number of computers in your enterprise. The DAS controls the flow of data between the database, Consolidators, the Microsoft Operations Manager Administrator console, and the Web console.
A repository for configuration information and collected data for a configuration group.
|Web Console Server|
A component installed on a computer running Microsoft Internet Information Services (IIS) that hosts the Web console.
|Microsoft Operations Manager Administrator Console|
A component installed on a computer running IIS that hosts the Web console.
In addition to the core components of MOM, Hosted Messaging and Collaboration provides:
|Hosted Exchange Management Pack|
The Hosted Exchange Management Pack contains over 100 rules organized within a comprehensive set of rule groups for monitoring critical aspects of your Hosted Exchange service. The parameters of each rule have been optimized to meet typical service provider needs.
The best way to view all available rules and up-to-date knowledge base content for any management pack, including any custom rules you may have chosen to add, is to view the Knowledge Base content through the MOM Administration Console. Note that the Hosted Messaging and Collaboration infrastructure, including MOM, must be in place before this Management Pack can be imported.
