What is SCOM (System Center Operations Manager)?

SCOM (System Center Operation Manager), in its shortest term, is a product of the System Center family that is customized to monitor and report our company. It is a product in our company where you can monitor almost all services, client computers, server systems, website contents, Linux and Windows systems, and you can get performance, accessibility reports at the end of the day and increase your awareness about your systems.

Operation Manager is a monitoring product that identifies the problem that sends warnings in case of a possible problem by collecting information about the status of the services and applications and devices it monitors, and also provides information about the solution, and also automates the solution of repetitive problems and minimizes the time spent on the solution of the problem. It provides management of Windows Linux and Unix servers on a single console. It can be integrated with System Center Virtual Machine Manager and System Center Orchestrator products, which are other System Center family products, and helps workflow management.

Operation Manager Architecture

When installing Operation Manager, we specify a management group. Each management group is formed depending on a management server, operational database and reporting data warehouse database.

The Management Server enables the information received by the management group to communicate with the database. The management server is managed by Operation Console and Web Console. A management group can contain one or more management servers and share its data.

An operational database is a database where data collected by the management group and configuration information of management groups are kept. The number of days that the data on this database will be kept by default is 7 days.

Data warehouse database

Data warehouse database aims to keep tracked objects and warnings longer. As soon as the data is written on the Operations Manager database, the data begins to be written on the warehouse database. It is recommended to be used in 10,000+ client designs.

SCOM Agent

Scom’s Opsmgr is the service that provides communication between the client. Using the management pack over the client, it gets the desired information. It collects data for the Agent Management group and reports it on the management server. In addition, the monitored computer sends the health status of the objects to the management server thanks to the agent.

Management Pack structure

It is the component that runs on Scom and transfers the information about the state of the compatible component to the management server. The agent manages the agent to send its own information from the installed computers. In order to monitor any application, it is necessary to have and install the management pack for that application. It contains more than one file in a management pack.
Management Pack gets its function from the .xml file inside.
Some XML files can be edited, while others come sealed in the .mp extension and cannot be changed.

The Management Pack of SCOM 2007 works on SCOM 2012 and above systems. However, although Custom Management Packs run on SCOM 2012 and above systems, editing cannot be made. The Shema used when creating the Management Pack with SCOM 2012 has changed. Therefore, Management Packs created with SCOM 2012 do not work in SCOM 2007.
