History
The product began as a network management system called SeNTry ELM, which was developed by the British company Serverware Group plc. In June 1998 the intellectual property rights were bought by Mission Critical Software, inc who renamed the product Enterprise Event Manager. Mission Critical undertook a complete rewrite of the product, naming the new version OnePoint Operations Manager (OOM). Mission Critical Software merged with NetIQ in early 2000, and sold the rights of the product to Microsoft in October 2000. It was renamed Microsoft Operations Manager (MOM) and had another release as Microsoft Operations Manager 2005. Microsoft renamed the product System Center Operations Manager and released System Center Operations Manager 2007. System Center Operations Manager 2007 was designed from a fresh code base, and although sharing similarities to Microsoft Operations Manager, is not an upgrade from the previous versions.

The Operations Manager Infrastructure
Management Servers
The role of the management server is to administer the management group configuration, administer and communicate with agents, and communicate with the databases in the management group. When two or more management servers are added to a management group, the management servers become part of a resource pool and work is spread across the members of the pool. When a member of the resource pool fails, other members in the resource pool will pick up that member’s workload.
Agents
An Operations Manager agent is a service that is installed on a computer. The agent collects data, compares sampled data to predefined values, creates alerts, and runs responses. A management server receives and distributes configurations to agents on monitored computers.
Services
- System Center Management Health service sends collected data and events to the management server
- Management servers also run the System Center Data Access service and the System Center Management Configuration service.
- The System Center Data Access service provides access for the Operations console to the operational database and writes data to the database.
- The System Center Management Configuration service manages the relationships and topology of the management group. It also distributes management packs to monitored objects.
Management Packs
The workflows that the System Center Management service runs are defined by management packs. Management Pack contains rules and monitors that collect and evaluate events and operations that are important to ensuring the health and efficiency. A rule defines the events and performance data to collect from computers and what to do with the information after it is collected. A simple way to think about rules is as an If/Then statement. Rules can also run scripts, such as allowing a rule to attempt to restart a failed application.
