Sun Management Center Web Interface |
Note - This feature may or may not be available on your system, depending on your licensing agreement.
This chapter covers the following topics:
The Sun Management Center Web Interface is a web-based management interface for the Sun Management Center platform. It is a host management system that uses HTTP protocol to provide easy access to Sun Management Center management information. Sun Management Center users can access the Web Interface across the firewall to monitor and manage Sun Management Center information from any location using widely-available web browers, such as Netscape Navigator and Internet Explorer.
The Sun Management Center Web Interface provides most of functions of the Sun Management Center Java Console for host management. It allows users to monitor and manage alarms and modules, and rapidly navigate the managed objects.
TABLE 18-1 lists the functions that are provided by the Web Interface and the chapters in which the corresponding Java-based functions are described. This chapter describes the Web-based functions and use.
The Sun Management Center Web Interface is an optional Sun Management Center component. It depends on the Sun Management Center Server for retrieving and manipulating managed objects.

To Start the Sun Management Center Web Interface |
| 1. | Start your web browser. |
Note - You do not have to be superuser to run the Sun Management Center from your web browser.
| 2. | Enter the Sun Management Center web location URL:
|
| 3. | The Sun Management Center Login page (FIGURE 18-1) is displayed. |
| This Login Page is for entering your user ID and password. The Sun Management Center server and web server are on the same host. |
| 4. | Log in using a valid UNIX account. |
| This account must be listed in the /var/opt/SUNWsymon/cfg/esusers file on the Sun Management Center server. |
| After you log in successfully, the Main Console (FIGURE 18-2) is displayed. |
All available domains are displayed in a drop-down Domain options menu. You can select one domain at a time to monitor or manage objects that are under the selected domain.
When you select a domain (FIGURE 18-2), the object hierarchy tree is displayed. Each tree node represents a topology object. If the there are child objects under the node, the tree node can expand or collapse. All tree nodes are displayed along with their associated icons, such as topology type icon, alarm icon, and expandable (or collapsible) icons for group objects.
A domain alarm state status icon for the selected domain is displayed next to the domain icon. A time stamp display above the domain name shows when the current page was loaded from the server.
Selecting a domain splits the page in two. The contents view (right side) of the screen displays the details about the selected host, including the state of the machine and a time stamp. A hyper-link enables you to display the Host Details page, which provides additional object/module monitoring information and management capabilities. Only host objects can be selected.

The Web Interface Alarms Manager is almost identical to the Sun Management Center 3.0 Alarms Manager described in Chapter 12. For Web Interface Alarm Manager details, see Chapter 19. When Auto refresh is enabled, all operation buttons and the selection column (column one) are disabled.
The Alarms page is similar to the Sun Management Center 3.0 Alarms Details window. Auto Refresh Disable enables all of the operation buttons, except the Filter button, and disables the selection column (column one).
View Alarms in the Options menu enables you to filter the alarms table by severity, open or closed alarms, and/or acknowledged or unacknowledged alarms. FIGURE 18-8 shows the View Specific Alarms dialog. For details, see Chapter 19.

The alarms table is filtered and redisplayed to reflect your selections.
The Modules page displays all available modules and their status (that is, whether they loaded or unloaded, and for the loaded modules, whether they are enabled or disabled). Modules can be loaded, unloaded, enabled, and disabled by an authorized user only.
Note - To load or unload and enable or disable a module you must have the appropriate security permission. For more information, see Chapter 14.
The Host Details Modules page is similar to the Module Loader window described in Chapter 6. In some cases editing can be done on the Host Details Modules Page. TABLE 18-3 lists the Host Details Modules page hyperlinks.

For more detailed information about web server administration, refer to the FastTrack Online Help.
Note - The Web Console runs under your Web Browser. Thus, you can change the font size. If you select a very large font, some pop-up windows may be too small to display all contents correctly. You can enlarge the windows to display them properly. All pop-up windows sizes are based on a 12-pixel font, so we suggest using this size font for the Web Console.
