Understanding Management Pack Operations

適用於: Operations Manager 2007

This section provides information about the types of objects the Windows Server Internet Information Services 2000 and 2003 Management Packs for Operations Manager 2007 discover, how health rolls up, the key scenarios, and a discussion of how you can view your monitoring information in the Operations Manager 2007 Operations Console.

Objects the Windows Server Internet Information Services 2000 and 2003 Management Packs Discover

The Windows Server Internet Information Services 2000 and 2003 Management Packs provide the object discovery rules listed in the following table. For more information about an object discovery rule, view the properties of the rule, and then click Product Knowledge. To access object discovery rules, go to the Object Discoveries node under the Management Pack Objects node in the Operations Console Authoring pane.

How Health Rolls Up

The Windows Server Internet Information Services 2000 and 2003 Management Packs monitor the IIS Server as a hierarchy of related components. The following illustration is a diagram view of an IIS 2003 Server object and all objects that have relationships with it. The top level of the hierarchy is the IIS Server object, at the lowest level are the Web Sites, Application Pools (IIS 2003 only), FTP Sites, NNTP Virtual Servers, and SMTP Virtual Servers.

The health of the IIS Server is dependent on the health of the objects at the next lower level, the IIS Web, FTP, NNTP, and SMTP Servers. When any one of these servers is in a critical health state, by default, the IIS Server is in a critical health state. This action is called "rolling up health."

The health of the IIS FTP, NNTP, SMTP, and Web Servers are not, by default, dependent on the health of the objects at the next lower level. If, for example, one or more Web Sites are in a critical state, the Web Server object will not change state. A Web Server is not necessarily having problems if one or more of its Web Sites are in a critical health state.

Key Monitoring Scenarios

The Windows Server Internet Information Services 2000 and 2003 Management Packs include monitors, rules, alerts, views, and reports to help manage the availability, configuration, performance, and security of IIS 2000 and 2003.

A monitor can change the health state of an object, such as from Healthy to Critical, but a rule cannot; both can generate alerts. Views can be looked at in the Operations Manager 2007 Operations Console and the Web Console. The monitors, rules, and alerts can be enabled, configured, and disabled through overrides, according to your requirements.

It is recommended that you create Management Packs exclusively for containing the overrides you create for the Windows Server Internet Information Services 2000 and 2003 Management Packs. These Management Packs enable you to verify your overrides in a test environment, export the Management Packs you created, and then import the Management Packs to your production environment.

Notifications can be configured for an alert so that the appropriate people are notified when a specific alert occurs. This enables the IT team to quickly respond to issues, helping to prevent an interruption of service. For more information about configuring notifications, see the About Notifications in Operations Manager 2007 topic in the Operations Manager 2007 Help.

The following sections describe key scenarios for managing Internet Information Services 2000 and 2003 with Operations Manager 2007.

Is My IIS Web-Based Application Healthy?

Operations Manager 2007 shifts the paradigm from managing individual computers to defining and managing the distributed applications you provide, such as Web-based applications. Managing applications, not just the computers they run on, enables you to more effectively and efficiently identify, analyze, and resolve issues related to these applications. This paradigm shift helps ensure that you are able to meet the applications' service level agreements you have agreed to with your customers.

Many objects that you can monitor, such as Web-based applications, are similar to each other. Operations Manager 2007 provides the Distributed Application Designer and templates for similar objects, much like Microsoft Word provides templates for common document types. These templates make it easier for you to accurately and quickly define and, subsequently, monitor the distributed applications you are responsible for.

Your customers' ability to access and use a Web site, for example, depends on more than just the health of the Web site. It may depend on components, such as a SQL Server 2005 database.

The Operations Manager 2007 Distributed Application Designer and Line of Business Application template allow you to more easily and accurately define, and therefore monitor, the end-to-end health of your Web-based applications. The health and relationships of individual components can be defined, monitored, and rolled up to the overall health of your application.

The Windows Server Internet Information Services 2000 and 2003 Management Packs discover and monitor the health of IIS 2000 and 2003 servers and related components. In conjunction with other Management Packs, such as Windows Server 2003 Operating System and SQL Server 2005, you can get a clear understanding of the health of your distributed Web-based application, and thereby also understand your customers' ability to access and use the application.

To fully utilize the Distributed Application Designer, it is recommended that you at least import the applicable Windows Server Operating System and Microsoft SQL Server Management Packs and add the relevant components to the Distributed Application Definition. The latest versions of the Management Packs can be found at https://go.microsoft.com/fwlink/?LinkId=82105. The versions of the Management Packs that shipped with Operations Manager 2007 are in the ManagementPacks directory of the installation media.

To create a distributed application definition for a Web-based application

1. Open the Operations Manager 2007 Operations Console.

2. In the navigation pane, click Authoring.

3. In the Authoring pane, right-click Distributed Applications, and then click Create new distributed application.

4. When the Distributed Application Designer displays, do the following:

   1. Type a Name, such as LOBWebApp1.

   2. Select the Line of Business Web Application in the Template list.

   3. Save the Distributed Application Definition to a Management Pack, such as LOBWebApp1MP.

      注意

      It is a best practice to save a distributed application definition to a Management Pack specifically for the application.

   4. Click OK.

5. On the Distributed Application Designer menu, click Save.

To add Web sites and databases to the distributed application definition

1. In the navigation pane of the Distributed Application Designer, click Web Site.

2. Select the Web sites for this application, and then drag them to the LOBWebApp1 Web Application Web Sites box.

3. In the navigation pane, click Database.

4. Select the databases for this application, and then drag them to the LOBWebApp1 Web Application Database box.

5. On the Distributed Application Designer menu, click Save.

Add components, such as Information Worker Windows Internet Explorer Clients, and create relationships between them until the distributed application definition accurately reflects your Web-based application and its clients. For more information about the Distributed Application Designer and templates, see https://go.microsoft.com/fwlink/?LinkId=86800.
