Sun Management Center
This chapter describes SunMC. The chapter contains the sections:
Sun Management Center software provides enterprise-wide monitoring of Sun servers and workstations, including their subsystems, components, and peripheral devices. The system being monitored must be up and running, and you need to install all the proper software components on various systems in your network.
Sun Management Center lets you monitor the following items on the Sun Fire V125 server (TABLE 4-1).
Sun Management Center consists of three components:
You install agents on systems to be monitored. The agents collect system status information from log files, device trees, and platform-specific sources, and reports that data to the server component.
The server component maintains a large database of status information for a wide range of Sun platforms. This database is updated frequently, and includes information about boards, tapes, power supplies, and hard drives as well as operating system parameters like load, resource usage, and drive space. You can create alarm thresholds and be notified when these are exceeded.
The monitor components present the collected data to you in a standard format. Sun Management Center software provides both a standalone Java application and a browser-based interface. The Java interface affords physical and logical views of the system for highly-intuitable monitoring.
Sun Management Center software provides you with additional tools, which can operate with management utilities made by other companies.
The tools are an informal tracking mechanism and the optional add-on, Hardware Diagnostics Suite.
Sun Management Center agent software must be loaded on any system you want to monitor. However, the product enables you to informally track a supported platform even when the agent software has not been installed on it. In this case, you do not have full monitoring capability, but you can add the system to your browser, have Sun Management Center periodically check whether it is up and running, and notify you if it goes out of commission.
The Hardware Diagnostic Suite is a package which you can purchase as an add-on to Sun Management Center. The suite lets you exercise a system while it is still up and running in a production environment. See Hardware Diagnostic Suite for more information.
If you administer a heterogeneous network and use a third-party network-based system monitoring or management tool, you might be able to take advantage of Sun Management Center software's support for Tivoli Enterprise Console, BMC Patrol, and HP Openview.
Sun Management Center software is for system administrators who have large data centers to monitor or other installations that have many computer platforms to monitor. If you administer a smaller installation, you need to weigh Sun Management Center software's benefits against the requirement of maintaining a significant database (typically over 700 Mbytes) of system status information.
The servers to be monitored must be running, Sun Management Center relies on the Solaris OS for its operation.

Sun Management Center features an optional Hardware Diagnostic Suite, which you can purchase as an add-on. The Hardware Diagnostic Suite exercises a production system by running tests sequentially.
Sequential testing means the Hardware Diagnostic Suite has a low impact on the system. Unlike SunVTS, which stresses a system by consuming its resources with many parallel tests (see SunVTS), the Hardware Diagnostic Suite enables the server to run other applications while testing proceeds.
Use the Hardware Diagnostic Suite to identify a suspected or intermittent problem with a noncritical part on an otherwise functioning system. Examples might include questionable drives or memory modules on a server that has ample or redundant disk and memory resources.
In such cases, the Hardware Diagnostic Suite runs unobtrusively until it identifies the source of the problem. The machine under test can be kept in production mode until and unless it must be shut down for repair. If the faulty part is hot-pluggable or hot-swappable, the entire diagnose-and-repair cycle can be completed with minimal impact to system users.
Since it is a part of Sun Management Center, you can only run Hardware Diagnostic Suite if you have set up your data center to run Sun Management Center. You must dedicate a master server to run the Sun Management Center server software that supports Sun Management Center software's database of platform status information. In addition, you must install and set up Sun Management Center agent software on the systems to be monitored. Finally, you need to install the console portion of Sun Management Center software, which serves as your interface to the Hardware Diagnostic Suite.
Instructions for setting up Sun Management Center, as well as for using the Hardware Diagnostic Suite, can be found in the Sun Management Center Software User's Guide.
