This chapter discusses the following topics:
Sun Management Center Overview
Sun Management Center software is an open and extensible system management tool
that enables you to:
The Sun Management Center product is divided into a set of three base components.
This section discusses the following topics:
The installation and setup of all Sun Management Center software, including
add-on products, can be performed with a single installation command as described
briefly in Chapter 1, Installing Sun Management Center 4.0 and in greater detail in Chapter 6, Installing and Updating Agents and Installing on Microsoft Windows.
Sun Management Center Architecture and Base Components
The Sun Management Center software management
framework is based on a three-tier architecture consisting of the Sun Management Center console,
server, and agent components, which provide the core Sun Management Center functions.
Figure 2–1 Sun Management Center Basic Architecture
-
The Server
executes management tasks and sends requests to Sun Management Center agents to perform
management tasks. The server stores network hardware and software information
as well as network and Sun Management Center configuration in a database. The Sun Management Center server
is normally installed on a single dedicated machine, and only one Sun Management Center server
is required on a network.
-
The Agent responds to the Sun Management Center Server directives, accesses
management information on the local machine, provides alarm determination,
and monitors local resources. The agent is automatically installed on the Sun Management Center server
machine and must be separately installed on any machine that you wish to monitor.
-
The Java Console is the graphical user interface that you
use to monitor your network and run network management tasks.
-
The web console is an alternate user interface to the Java
Console and has a subset of the Java Console's features.
-
The Sun Management Center Web
server is installed with the server layer on the same host as the server layer.
The Web Server enables you to access the Sun Management Center web console
from any system that supports any one of the following Web browsers:
-
Internet Explorer 6.0
-
MozillaTM 1.7
-
Firefox 2.0
Sun Management Center initiates operations
by sending requests to the Sun Management Center agents installed on each system.
Based on SNMP technology, the agents process server requests. The agents also
act autonomously, collecting and processing data locally. Agents can act on
observed conditions to send SNMP traps (messages sent when errors or specific
events occur on the network) or execute management operations. The agents
can raise alarms or initiate specific actions through customized rules and
thresholds even when connection to the manager is severed. For further information
about SNMP, see Security Keys and SNMP Community String and SNMP Daemons and Legacy Agents.
Management and monitoring functions of the Sun Management Center agent are structured
into loadable modules. The agent modules provide flexibility, enabling you
to establish as little or as much monitoring and management as required on
a per system basis. Additional modules can be dynamically loaded into Sun Management Center agents
from the Sun Management Center console without disruption of the management or agent
systems. For further information about Sun Management Center modules, see Appendix
C, Sun Management Center Software Modules, in Sun Management Center 3.6.1 User’s Guide.
Sun Management Center Base Add-on Products
Sun Management Center provides four add-ons that are distributed as part
of the Sun Management Center distribution on the media or the Web download image:
-
Advanced System Monitoring - Provides full kernel reader functionality,
Solaris health monitoring, file system monitoring, directory size monitoring,
process monitoring, IPv6 protocol monitoring, MIB-II Instrumentation, and
log viewing.
-
Performance Reporting Manager - Adds analysis, reporting, and
graphing capabilities.
-
Service Availability Manager - Tests and measures the availability
of network services including DNS and NIS naming services, Web server, directory,
LDAP, Telnet, FTP, mail, and Solaris calendar services.
-
System Reliability Manager - Enhances reliability, helping to
increase service levels and decrease administrative costs.
For detailed information about base add-on and additional add-on products,
see the Sun Management Center Web site at http://www.sun.com/software/solaris/sunmanagementcenter/.
Additional Add-on Products
Depending on the hardware platform on which you are installing Sun Management Center software,
your system might require additional platform-specific add-ons. The add-on
products provide additional functionality such as additional support for specific
Sun hardware architectures, configuration readers, and new agent management.
For information about a specific hardware platform, see the Sun Management
Center supplement for your hardware platform. For information about additional
add-ons for Sun Management Center, see the http://www.sun.com/software/solaris/sunmanagementcenter/ Web site.
Note –
You should always read your Sun Management Center supplement for architecture-specific
installation instructions before installing Sun Management Center software on a particular
hardware platform.
Add-on products are released in one of the two ways:
Add-on products released as part of the Sun Management Center distribution are
installed during the installation process. The basic components are installed
first, followed by installation of the add-on products.
Many add-on products offer architecture-specific support. Therefore,
the installation checks your hardware. For example, if an add-on product
supports workstation systems, you are given the opportunity to install the
workstation add-on when you install Sun Management Center on a workstation host. In
most cases, user confirmation is required prior to installing an add-on product.
If the add-on product is released separately from the Sun Management Center distribution,
the add-on product includes its own installation instructions in the accompanying
supplement.
Sun Management Center Directories
After a successful installation and setup on the Solaris platform, directories
are created as shown in Table 2–1.
On Microsoft Windows, only the C:\Program
Files\SUNWsymon directory
is created.
Table 2–1 Sun Management Center Default
Solaris Directories

Sun Management Center System Files
This section describes the system files modified by installation of Sun Management Center,
and provides an overview of operating system patches.
/etc/group File
The Sun Management Center software installation program adds the groups esadm, esdomadm, and esops to the
local /etc/group file on the machine. A group entry is
created for the database group smcdbg in /etc/group on
the machine where the Sun Management Center server is installed.
The user specified as the administrator during Sun Management Center setup is
added to the esadm and esdomadm groups.
For example, if the root user account is specified as the Sun Management Center administrator,
the installation program appends the following lines to /etc/group:
smcdbg::98194049:
esadm::1000:root
esdomadm::1001:root
esops::1002:
/etc/passwd File
The Sun Management Center software installation adds the user smcdbu to the /etc/passwd file. The smcdbu user account is needed
to run the database on the Sun Management Center server layer.
/var/opt/SUNWsymon/cfg/esusers File
The /var/opt/SUNWsymon/cfg/esusers file is used
to define authorized Sun Management Center users. For further information, see Users, Groups, and Roles Overview.
Supported Platforms
For the latest information on supported hardware platforms, see the Sun Management Center Web
site at http://www.sun.com/sunmanagementcenter.
Sun Management Center uses modules to monitor and manage the resources of systems,
applications, and network devices. The module defines a collection of objects
to be monitored by the agent. The Config-Reader module is required for hardware
configuration information.

Provide a password to generate the security key.
The
password must be the same password you provided when you set up Sun Management Center 4.0 server.
-
Provide an SNMPv1 security string.
The security
string must be the same security string you provided when you set up Sun Management Center 4.0.
To Install the Sun Management Center Console on Microsoft
Windows
If a previous Sun Management Center console version is installed on the Microsoft
Windows machine, uninstall the console as described in Uninstalling Sun Management Center From the Microsoft Windows Platform.
To install the Sun Management Center 4.0 console, install the console
as described in Installing Sun Management Center 4.0 on Microsoft Windows.
Service
Tag Registration
Sun Management Center 4.0 registers its own service tag by using the
Solaris stclient interface. Information such as the product
name, product version, architecture, and zone name (if any) are registered.
Sun Management Center 4.0 also inserts its unique product identifier information
in the service tag registry, which identifies this product within Sun Microsystems.
However, sensitive information like the host name or hardware are not inserted.
Note –
Sun Management Center only inserts the information. You can send
this information back to Sun Microsystems using the Product Client Registration
mechanism of the Sun Connection product. Sun Management Center does not, in
any form, transmit this information back to Sun on its own.
When you invoke Sun Management Center, the installation performs the
following tasks:
-
Checks whether the registration is for an agent or a server.
-
Retrieves the unique resource identifier of the server for
an agent-only installation from the installation registry file.
-
Registers the agent in the server host's stclient registry
file. This parent-child relationship mapping enables the Sun Microsystems
Incorporation (SMI) central server or the registration tags central repository
to determine the number of nodes that a given registered Sun Management Center
server is managing.
Solaris Packages for Service Tags
For Solaris 8, 9, and 10 versions, service tags are available as Solaris
packages. You can download a service tag for the Solaris Operating System
from http://www.sun.com/download/. The Solaris
packages are as follows:
Sun Management Center Java Console Using
Java Web Start
Sun Management Center 4.0 supports the Java Web Start based console.
To start the Sun Management Center Java console through Java Web Start, you
must install both the server and the console layers. When the setup detects
that both the server and console layers are installed, the following tasks
are processed:
-
The client API JAR files in the BASEDIR/SUNWsymon/classes directory are copied and signed in BASEDIR/SUNWsymon/web/console/lib.
-
The localization messages files in the SUNWsymon/lib/locale directory are combined into a JAR file and signed.
-
The JAR files in the BASEDIR/SUNWsymon/apps/classes directory are combined into a JAR file and signed.
The BASEDIR/SUNWsymon/web/console/lib directory
forms the basis of the Java Web Start configuration for Sun Management Center.
A script creates the Java Network Launch Protocol (JNLP) file at runtime using
this directory as the web server's web application directory.
The setup uses the location and organization that you specify during
the web console setup to generate the keystore for authenticating the Java
Web Store based console certificates.
To Start the Java Web Start Based Sun Management Center
Console
-
Type http://server-name:webserver-port/smconsole.jnlp in your browser.
-
Type your login name and password.
