Monitoring the Server System Using the Web GUI
This chapter provides information about how to use the web GUI and the Sun Fire X4150 server software to monitor your server.
It includes the following sections:
|Note - You can monitor the rudimentary state of the server using the LED fault light. A solidly lit amber LED indicates critical error. Further details about the fault light can be found in your Service Manual. For information about controlling the state of the fault LEDs see To Manage the State of the System Locator Indicator LED.|
The web-based graphical user interface (GUI) allows you to use a standard web browser to monitor and manage local and remote systems.
You can redirect the server’s console to a remote workstation or laptop system. 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 files) and CD-ROM images (.iso files) 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 web browsers, and might be compatible with other web 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 5.
After you log in to the web GUI, you can perform basic software tasks, Intelligent Platform Management Interface (IPMI) tasks, and system monitoring.
ELOM user accounts define what you can do by roles:
For more information about users, including how to manage user accounts using the web GUI, see Chapter 4.
Some of the common tasks you can perform using the web GUI include:
Configuring connection methods:
Monitoring and managing system status:
Managing and modifying system variables:
The ELOM boots automatically when a Sun server is cabled appropriately and plugged in to an AC power supply. 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 the browser response time.|
1. To log in to the web GUI, type the IP address of the ELOM in your web browser.
The login screen appears.
2. In the login screen that appears, type the default user name and password.
3. Click Log In.
The web GUI appears.

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 tabs.
From the Versions submenu, select the SP Version tab.
The SP Version screen appears, displaying information about the server board installed in the system. It presents the information in a tabular format. For example, TABLE 3-2 shows a sample of the SP information as it is displayed in the SP Version screen:
From the Versions submenu, select the Server Board Information tab.
The Server Board Information screen appears, displaying information such as the BIOS version and the serial number. It presents the information in a tabular format. TABLE 3-3 show a sample of the server board information as it is displayed:
The CPU menu selection provides information about the processor.
From the System Information menu, click the Components submenu tab, then select CPU.
The CPU information screen appears. The CPU information is presented in a tabular format. A separate table of information is available for each of the server’s CPUs, whether a CPU is installed or not. TABLE 3-4 shows a sample of the CPU information for CPU0:
From the System menu, select Components, and then select Memory.
The Memory screen appears. It displays information about total memory installed in your server; see TABLE 3-5.
The Memory screen also displays information about each DIMM installed in your system, presenting it in a tabular format that includes such information as the memory module number, the status, and module size; see TABLE 3-6 for a sample of the memory information for DIMM_A0.
Sensors placed throughout the system provide information about the state of critical server components. The sensors read temperature and voltage and report on 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 or DIMM and read the actual DC voltage of each of the system’s power supply lines. The System Monitoring submenu screens also allows you to view and manage the system log, the Locator Indicator LED, and the Fault LED. For information about the Locator Indicator LED and the Fault LED, see Managing the State of the System Locator Indicator LED.
On the main menu, click System Monitoring.
The System Monitoring submenu appears, allowing you to view the Sensor Reading, Event Logs, Locator Indicator, and Fault LED tabs.
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 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 power, the temperature of all critical components, and each of the monitored voltage lines. For example, TABLE 3-7 shows the top portion of the summary table summarizing the status of the Fault LED and the system power.
TABLE 3-8 shows a detail of the Summary table that summarizes the status of each of the system fans.
TABLE 3-9 shows a detail of the Summary table that summarizes the status of the temperature sensors.
