Monitoring the Server System Using the Web GUI |
This chapter provides information about how to use the web GUI and the Sun Blade X6250 server module software to monitor your server.
It includes the following sections:
The web GUI allows you monitor and manage local and remote systems, using a standard browser.
You can also monitor the server remotely by redirecting the server’s console to a remote workstation or laptop. This requires configuring the remote system's keyboard and mouse to act as the server's keyboard and mouse. You can configure the diskette drive or CD-ROM drive on the remote system as if it were connected to the Sun server. You can also redirect diskette images (.img) and CD-ROM images (.is) for remote access. Remote configuration issues are covered in Chapter 5.
The web GUI has been tested successfully with recently released Mozilla
Firefox, and Internet Explorer browsers, and may be compatible with other browsers.
The ELOM product is preinstalled on the Sun server. However, you need Java software on the client to perform redirection as described in Chapter 10.
After you log in to the web GUI, you can perform management, basic software tasks, Intelligent Platform Management Interface (IPMI) tasks, and system monitoring.
ELOM permissions for user accounts define user limitations. For example:
administrator - Enables full (unlimited) read and write access to all ELOM software features, functions, and commands.
operator - Enables read-only access to a limited number of ELOM software features, functions, and commands, plus management access to Indicator and Fault LEDs.
user and callback- Enables read-only access to a limited number of ELOM software features, functions, and commands.
For more information about user accounts, including setting permissions and changing passwords using the web GUI, see Managing User Accounts.
Some of the common tasks you can perform using the web GUI include:
Monitor and manage system status
Manage and modify system variables
The ELOM boots automatically when the server module is inserted into a powered chassis. This usually occurs within one minute. However, if the management Ethernet is not connected, or if the ELOM's Dynamic Host Configuration Protocol (DHCP) process fails due to the absence of a DHCP server on the management network, the ELOM might take a few minutes longer to boot.
| Note - Disabling the use of the browser proxy server (if one is used) for access to the management network might speed up the response time. |
|
1. To access the web GUI, enter the IP address of the ELOM in your browser.
2. Type a user name and password.
To configure and manage the server use a user account with administrator privileges.
The Log Out button is located at the top right of the interface screen.
Your server is equipped with a number of sensors that measure component voltages, temperatures, and fan speed. The System Information tab reflects the current system status.

The following section describes how to monitor the server using the browser and the ELOM software.
The System Information tab provides information about server board and system components, such as the service processor (SP), the CPU, the memory, and the network interface cards (NIC). Details are found in the Versions and Components submenu tabs.
| Note - The service processor (SP) is also referred to as the BMC. Wherever BMC is mentioned, consider it different terminology for the SP. |
|
On the main menu, click the System Information tab.
The System Information submenu appears, allowing you to view the Versions, Session Time-Out, and Components submenu tabs.
|
From the Versions submenu, select the Server Board Version tab.

|
From the Versions submenu, select the BMC Version tab.
The BMC Version screen appears. It displays information about the BMC installed in the system, and presents the information in a tabular format. For example:
|
From the System Information menu, click the Components submenu tab, and then select CPU.
The CPU information screen appears. The CPU information is presented in a tabular format (see TABLE 3-4). A separate table of information is available for each of the server’s CPU, regardless if a CPU is installed or not.
|
From the System Information menu, click the Components submenu tab, and then select Memory.
The Memory submenu screen appears. It displays information about each of the DIMMs installed in your server. The CPU information is presented in a tabular format (see TABLE 3-5).
|
From the System Information menu, click the Components submenu tab, and then select NIC.
The NIC submenu screen appears. It displays information about the network interface card installed in your server. The NIC information is presented in a tabular format (see TABLE 3-6).
Sensors placed throughout the system provide information about the state of critical server hardware. The sensors allow the system to monitor temperature, voltage, and operational status. Using the System Monitoring submenu screens you can view the these sensors, and monitor the health of your server’s critical components. For example, you can check the temperature of each CPU and the voltage level of the system’s DC voltage lines. The System Monitoring submenu screens also allow you to view and manage the system log, the System Indicator LED, and the Fault LED. For information about the System Indicator LED and the Fault LED, see Chapter 4.
|
On the main menu, click System Monitoring.
The System Monitoring submenu appears, allowing you to view the Sensor Reading, Event Logs, System Indicator, and Fault LED tabs.
The Sensor Reading Tab provides access to the Sensor Summary, the Temperature, Voltage, and Chassis Status screens.
|
From the System Monitoring tab, click the Sensor Reading Tab.
The Sensor Reading tab allows you to select the Summary, Temperature, Voltage, and Chassis Status tabs.
|
From the Sensor Reading submenu tab, select the Summary tab.
The Summary screen appears. It provides an overview of the status of the system sensors. The screen provides the status of the Fault LED, the server’s power status, the temperature status of all critical components, and the status of each of the monitored voltage lines.
|
From the Sensor Reading submenu tab, select the Temperature tab.
The Temperature screen appears. It provides the status, the actual temperature, and the upper critical and non-critical temperature thresholds for each system-critical component. The Temperature submenu screen displays the information in a tabular format. It provides a separate table for each component. TABLE 3-7 shows a sample of the temperature monitoring readings for CPU 0.
A similar panel is repeated for each monitored entity.
