Object: YesA computer, a DNS region, an instance, And A Logical Disk are basic units of management, and objects all have their own attributes.

Class:The abbreviation of a class object, or a group of objects with the same attributes constitute a class. An object is also called a class instance. The class contains several types of objects (for example, there are several objects in the Windows 2003 computer class). You can monitor the same type of computers in a unified manner.

Object discovery:Registry, WMI, script, ole db, LDAP, and custom Management Code.

Displays the relationships between objects, classes, and attributes.

Monitor:Used to monitor whether something is good or bad. In operations manager, a monitor is an element in the management package that defines the logic used to determine the object's running status. The monitor can set the running status.

The basic health model of an object is divided into four aspects.: Availability (the server service is running), performance status (CPU Io, etc.), security and health, and configuration check (check the configuration through best practices ). For example.

Rules:Using rules to collect data of an object does not affect the object's health. More information is collected (such as Performance Logs and system logs) and displayed to the scom server. In operations manager, rules are the elements in the management package that define the event and performance data to be collected from the computer and how to process the collected information. The running status cannot be set for the rule.

Alert: used for event management and issue tracking.Do not close alert. If the problem persists but is disabled, alert will not be generated when the script is executed again. Some alarms do not have the automatic repair function and need to be reset manually.

When an alarm is created by a monitor or rule, the action of the alarm is different ,.

Knowledge Base:All monitors have a knowledge base to tell the problem's situation, cause, and solution. When creating a monitor, you can write or modify the knowledge base. The knowledge base of an existing Official Monitor cannot be changed.

Task:Two types: console and agent. A predefined workflow is used to capture or represent a common operation. You can view the results in the console.

Tasks that can be executed by the console and tasks that can be executed by the agent (using the default agent account ).

For example, if the service is stopped and the problem is diagnosed, the service is automatically started.

Override:The thresholds defined in the product package are preset and may not be suitable for all enterprises. Therefore, they can be modified according to the actual situation of the enterprise. If the value of override is not too sure, it is best to test it in the test environment first.

For example, some default monitoring threshold settings may be inappropriate. You can modify the override management package to the appropriate value.

When managing an override management package, it is best not to modify it on the default management package. You can create a new management package.

Advantages of override:Management packages released by Microsoft are encapsulated and cannot be modified. management packages after override in the test environment can be imported to the production environment;

Default MP is a management package that is not encapsulated. The modified package is saved to this management package by default. We recommend that you do not save the override package to this management package, we recommend that you store it in a new management package.

Four types of override:

1. All objects of the class

2. Class-specific objects

3. All objects other than the specified object of the class

4. Target group

GROUP: YesGrouping based on logic, scom automatically groups some management packages, such as IIS and servers. You can subscribe to notifications based on different groups.

View:You can customize or use the default view. In the operation console, the view displays the filtered dataset in the operationsmanagerdb database.

Management package:A group of files you have installed that must be used with Operations Manager. These files allow you to monitor applications and add features to operations manager. The settings in the management package allow the agent to monitor specific services or applications in system center 2012-operations manager. These settings include allowing the Management Server to automatically detect and start monitoring object discovery information, a knowledge base containing error and troubleshooting information, alarm generation rules and monitors, and reports.

The management package may also contain tasks, diagnostic and recovery tools, and instructions to help solve problems.

New and updated management packages will be released continuously.

Management packages are encapsulated and not encapsulated.

Sealed:Binary. MP File

Unsealed:XML file, which can be encapsulated by Microsoft tools

Most of Microsoft's management packages are encapsulated.

Each management package may contain one or all of the following components:

1. Monitor, targeted proxy to track the status of different parts of the management component.

2. Rules, targeted proxy to collect performance and discover data, send alerts and events, and so on.

3. Task, which defines the activities that can be executed by the proxy or console.

4. Knowledge, provide text suggestions to help operators diagnose and solve problems.

5. View, which provides a Custom User Interface for monitoring and managing this component.

6. Report: defines the specific way to report information about this management component.

7. Object discovery: identifies the object to be monitored.

8. The running mode configuration file allows you to use different accounts on different computers to run different rules, tasks, monitors, or discoveries.
