The Operations Manager Infrastructure

Installing Operations Manager creates a management group. The management group is the basic unit of functionality in operations manager and it consist of a management server, the operational database, and the reporting data warehouse database.

  • The management server is the central point for administering the management group and communicating with the database. When you open the Operations console and connect to a management group, you connect to a management server for that management group. Depending on the size of your computing environment, a management group can contain a single management server or multiple management servers.
  • The operational database is a SQL Server database that contains all configuration data for the management group and stores all monitoring data that is collected and processed for the management group. The operational database retains short-term data, by default 7 days.
  • The data warehouse database is a SQL Server database that stores monitoring and alerting data for historical purposes. Data that is written to the Operations Manager database is also written to the data warehouse database, so reports always contain current data. The data warehouse database retains long-term data.

When Operations Manager reporting functionality is installed, the management group also contains a Reporting server which builds and presents reports from data in the data warehouse database.

These core components of a management group can exist on a single server, or they can be distributed across multiple servers, as shown in the following image.

Operations Manager Terminologies

SCOM Agent
This is the service installed on a system, which collects data, compare sample data with predefined values, create alerts and runs responses. Basically this is the software that you deploy to monitored systems in your environment. This collect data based on management packs you load on operations manager server.

Management Packs
Define the information that the agent you deploy to servers collects and return to the management server for specific application or technology. Once you deploy agent to machine, id does not do anything.
For an example, if you deploy agent right now from brand new operations manager server to exchange box, nothing going happen you can get only up down monitoring of that server which means operation manager server tell you that server is up or down you will not get exchange statistics, will not get windows statistics. The reason is because you haven’t add any management packs in order to tell operations manager what kind of information you want to monitor from operations manager framework. When you add exchange management packs to your operations manager server for example, thus all kind of metrics watched on exchange server discovered environment.
