Chapter 15 Managing Objects Using the Web Console

The Sun Management Center web console provides many of the same host management functions as the Sun Management Center Java Console provides. You can use the web console to monitor and manage alarms and modules. You can also use the web console to navigate the managed object topology. This chapter covers the following topics:

• Web Console Features and Functions

• Overview of Main Web Console Page

• To Start the Sun Management Center Web Console

• To View Detailed Information About a Host

• To Load a Module

• To View a Specific Log File

• Host Details Browser Page

• Attribute Editor in the Web Console

Web Console Features and Functions

The Sun Management Center web console is a web-based management interface for the Sun Management Center platform. This host management system uses the secure HTTPS protocol to provide easy access to Sun Management Center management information. You can access the web console across the firewall to monitor and manage Sun Management Center information from any location. You can use widely available browsers, such as Mozilla^TM1.4 or higher, Netscape Navigator^TM 4.5.1 or higher, and Internet Explorer 5.0 or higher.

The web console is an optional Sun Management Center component. The web console depends on the Sun Management Center server for retrieving and manipulating managed objects. For information about configuring the web server, see Sun Management Center 3.6.1 Installation and Configuration Guide.

The following table identifies the functions that the web console provides and relates the functions to the Java Console.

Overview of Main Web Console Page

The main web console page provides similar features to the main Java Console window. The left side of the page provides the hierarchy (tree) view for the current administrative domain. The right side of the page provides additional details about the item that is selected in the tree view.

From the main console page, you can perform the following tasks:

• Select another administrative domain to monitor or manage by choosing a domain from the Domain pop-up menu.

• View a summary of current alarms in the Status Summary section of the page.

• Expand the hierarchy to view additional levels of information within the current domain. For more information, see To View and Expand the Topology Hierarchy.

• Access detailed information about the currently selected managed object. For more information, see To View Detailed Information About a Host.

• Set options for automatically updating the contents of the main page by choosing from the Auto Refresh pop-up menu.

• Manually update the contents of the main console page by clicking the Refresh button.

• Exit from the web console by clicking the Logout button.

• View online information about the web console by clicking the Help button.

• Define and access alarms for a specific managed object. For more information, see Chapter 16, Managing Alarms Using the Web Console.

• View and edit attributes for a specific data property. For more information, see Chapter 17, Managing Data Property Attributes Using the Web Console.

By default, the object hierarchy tree for the Default Domain is displayed. Each tree node represents a managed object in the topology. All tree nodes are displayed with their associated icons, such as a topology type icon, an alarm icon, or an expansion icon for a group object. A triangle next to a node indicates that the managed object contains additional child objects. To view those child objects, click the triangle.

If any alarms apply to the domain, a status icon for the domain alarm state is displayed next to the domain icon. A timestamp display above the domain name shows when the current page was loaded from the server.

When you select a host object in the hierarchy view, information about that object appears in the right side of the page. The right side of the page displays general information about the selected host, including the state of the machine and a timestamp. To view additional information about the host object, click the Go to Details link. The Host Details page provides additional object and module monitoring information and management capabilities. For more information, see Host Details Browser Page.

The following table lists the buttons on the main console and Host Details pages and describes their functions.

Table 15–2 Buttons on the Main Console and Host Details Windows

Button	Function
Auto Refresh	Disables and enables the auto refresh feature. The Auto Refresh menu contains the following choices:  Disable 1 Minute 2 Minutes 3 Minutes 5 Minutes 10 Minutes The display refreshes according to the item that is selected. These options can be configured on the server through a configuration file.

Status Summary

The status summary displays the number of managed objects that have unacknowledged open alarms, by level of severity, in the selected administrative domain.

If a host has multiple alarms at several different severity levels, the host is represented at only the highest severity level for that host.

For more information about he status summary, see To View Alarms From the Main Console Window.
