NAME
insight_manager - Web-based device status and configuration
DESCRIPTION
Insight Manager is a Web-based utility that enables you to look across a
heterogeneous computing environment and access information about any device
connected to the network. Devices can be computer systems, networked
printers, or network components such as routers. You can obtain information
about the configuration of systems and their components or peripherals and,
in some cases, perform certain administrative tasks such as asset
management, asset security, work load management, and event management.
Web-based enterprise management (WBEM) protocols are able to communicate
among the following operating environments in addition to Tru64 UNIX:
OpenVMS, IBM OS/2, Microsoft Windows 2000(TM), Windows NT(TM), Windows
98(TM), Windows 95(TM), Novell NetWare, SCO OpenServer Release 5, and SCO
UnixWare 7.
Insight Manager features are fully implemented in some operating
environments, but are not yet implemented in others. This means that you
can use many features on Windows NT(TM) systems, but you cannot use certain
features on Tru64 UNIX. On a Tru64 UNIX system, you can use the Management
Agents to monitor devices, but you must invoke the SysMan Menu or SysMan
Station to perform configuration tasks. Insight Manager provides a
consistent wrapper for SysMan, enabling you to manage supported systems
from a web browser.
Insight Manager XE is a software console that provides full administrative
services for Windows NT. It is a server that can communicate with other
devices in the local area network or domain that run the Management Agents
(daemons).
A device must have an operating environment that is recognized by Insight
Manager to be able to manage it using WBEM. Such an operating environment
must be able to communicate device information to the WBEM network, and to
receive and execute instructions sent from other (authorized) devices in
the WBEM network.
The operating environments must be able to run Management Agents, which
communicate with each other using a standard protocol. Devices, and their
operating environments, provide information about hardware and software
status using a data model, such as a Management Information Base (MIB) and
Simple Network Management Protocol (SNMP). These can be thought of as a
database of objects, with attributes and values, representing the
manageable components of a device.
You can configure a system to participate in auto-discovery, which allows
any Management Agent to discover any other Management Agent in the local
network domain. This feature is turned off by default. The system with the
lowest numerical value for its IP address is the master for the subnet.
Configuration
The Management agents (daemons) are configured by default when you install
the operating system and are started automatically when the system boots.
The Web and threshold agents are initialized during transition to run level
3; the initialization script is located in /sbin/rc3.d/S50insightd. This
script runs /usr/sbin/insightd, /usr/sbin/sysman_hmmod,
/usr/sbin/config_hmmod, and /usr/sbin/cpqthresh_mib and prints a boot-time
message at the console when the agent is started successfully.
The SNMP subagents /usr/sbin/os_mibs and /usr/sbin/cpq_mibs also are
invoked during transition to run level 3 and are invoked by the
/sbin/rc.3d/S49snmpd script. To test that the system is properly
configured, enter the following commands:
# ps agx | grep insight
487 ?? S 0:35.63 /usr/sbin/insightd
500 ?? S 0:35.63 /usr/sbin/sysman_hmmod
501 ?? S 0:35.63 /usr/sbin/config_hmmod
# ps agx | grep cpq
560 ?? S 0:00.36 /usr/sbin/cpq_mibs
583 ?? S 0:35.63 /usr/sbin/cpqthresh_mib
# ps agx | grep os_mibs
552 ?? S 0:00.36 /usr/sbin/os_mibs
You can disable the Management Web Agent through the Set Up Insight Manager
system management task, which can be launched through the SysMan Menu or
the SysMan Station. See sysman(8) for more information.
You should configure the password settings for the Insight Manager
administration account when you first use it. The procedure is described in
the section of this reference page titled "Account Login home page."
See the Best Practice document titled "Configuring SNMP for Threshhold Set
and Trap Operations for Insight Manager" on the Tru64 UNIX documentation
web site for information on configuring SNMP so that the administrator can
set thresholds.
Browser Requirements
The minimum browser requirements include support for tables, frames, Java,
JavaScript, and the Java Development Kit (JDK) 1.1. Additional browsers, or
the browsers mentioned, used with different operating systems, may or may
not work correctly, depending upon their specific implementations of the
required browser technologies.
The requirements are TCP/IP and one of the following browsers:
___________________________________________________________________________
For client systems running Browser Requirements
___________________________________________________________________________
Tru64 UNIX Version 4.0F or higher Netscape Communicator 4.5 or higher
Tru64 UNIX 3.2C through 4.0E
inclusive
Netscape Communicator 4.06 or
higher
Windows 95, Windows 98, or Windows NT
3.51/4.0
Microsoft Internet Explorer version
4.72.2106.8 or higher or Netscape
Communicator 4.04 or higher
___________________________________________________________________________
You must turn on the following options so that the Management Agents work
properly:
· Enable Java
· Enable JavaScript
· Accept all cookies or
Accept cookies originating from the same server as the page being
viewed
Configuring the Java Plug-in for Netscape
You must install the Java plug-in to invoke the SysMan Menu or SysMan
Station as Java applets using Netscape. If you attempt to run an applet
such as SysMan Menu before installing the Java plug-in, the browser opens a
new web page in a separate window but is not able to complete the
operation. Close the new window.
The Java plug-in shipped with the operating system is designed to work only
with Netscape on this release of Tru64 UNIX. If you are using Netscape on
another platform, other Java plug-ins might be available for the user
environment of your choice. See the home page for your browser. Only the
Netscape browser is identified as the supported browser and has been tested
for this release.
The procedure to install the Java plug-in is described in detail in the web
page at /usr/share/sysman/web/plugin.html, which is displayed automatically
when you first attempt to use the Java applets. Print the page as you will
need to restart your browser during the installation and configuration of
the plug-in.
Using Insight Manager
You may connect to the Management Agents of any system in the local network
domain that is running the Management Agents.
Connect your web browser to port 2301 on any such system in the local area
network as follows:
http://system_name:2301
You also can specify the TCP/IP address in place of a fully qualified host
name, as in the following example.
http://20.111.333.10:2301
Connecting your web browser to port 2301 launches the Device Home Page of
the specified system.
Device Home Page
Successfully connecting to port 2301 displays the Web-based Management
Device Home Page. This page provides links to available Web-enabled
services as well as a Refresh link that reloads the The Device Home page.
The Device Home page, and the links from it will differ in content from the
home page on other systems, such as a PC running Windows NT.
Anonymous access to Web-enabled services is available without logging in
when the Device Home Page is launched for the first time. To log in as a
different user, select the Anonymous link.
The Web-enabled services available from the Device Home Page include:
· Management Agents Home Page
· Access Home Page
· Tru64 UNIX Configuration Report
· Tru64 UNIX SysMan
· WBEM Login Home Page
· WBEM Device Options Home Page
· WBEM Active Devices home page
Each of these web pages are described in the following sections.
Online help is available for any Management Agents web page; select the
question mark (?) icon to invoke it. This icon is a question mark in a
triangle, located at the top of the page.
Management Agents Home Page
The Management Agents page provides detailed information on the status of a
device, its operating system, and any device subcomponents that can be seen
by the Insight Manager agent. If the device is a computer, a subcomponent
can be a mass storage peripheral, such as a hard disk. This web page is
divided into three frames:
1. The Title frame contains a legend of color-coded icons that describe
the device and component status and the following links that can be
selected to display more information in the Summary (main) page:
Agent Help
Invokes the web-based help page
Summary Returns to the Summary (main) frame
Device Home
Returns to the Device Home page
Options Enables you to configure the presentation of device data, and
set values such as the refresh interval
2. The Navigation Frame, located below the Title Frame on the left side
of the browser window, lists all of the subsystems with components
that are available for this device. The content of this frame is
dependent on what data can be provided by the device to Management
Agents. Typical contents for a device that is part of a computer
system are as follows:
Configuration
Provides links to information on the system type, the main CPU
board, and the operating system software.
Mass Storage
Provides links to information on the disk devices and current
allocations of disk space in use by file systems. Also
included is information on device controllers, such as SCSI
controllers. If you select a SCSI controller, you can display
the buses and any disk devices connected to a bus. In turn,
you can select an individual disk, tape, and CD-ROM, and
display properties of that device.
NIC (Network Interface Card)
Provides links to information on the network interfaces and
any other communications interfaces that are configured, such
as a serial line interface. You can obtain information about
the device, such as its device type, physical address,
settings, and network statistics.
Utilization
Provides links to information on the CPU utilization with
aggregate load for the past 1, 5, 30, and 60 minutes.
Recovery
Provides links to information on environmental conditions such
as the status of the environmental monitoring subsystem (if
configured on the host), including power supply, system
temperature, and fan status. You also can display the log of
start-up messages that was saved when the system was last
booted.
3. The Summary frame is the main frame. The information for any links
selected in the preceding frames will be displayed here. When you
first access the Management Agents page, this frame contains
information that enables you to identify the device type and model,
its physical and network locations, and its general status. Use the
Summary link in the Management Agents frame to display this default
information.
Use the question mark (?) icon in the frame's banner heading to access
the Management Agents web-based documentation to provide you with more
information on all the Insight Manager pages.
Tru64 UNIX Configuration Report Home Page
On Tru64 UNIX systems, the configuration report is created by the sys_check
utility, which provides a system census report for the local host. If a
report has not been created, you can choose to launch the utility and
create a first report. Note that the report can take up to an hour to
generate, and may affect system performance.
If an existing report is found, the Configuration Report page is displayed
and you can browse its content. The report is useful for detecting system
configuration and tuning problems, log file and event file settings, and
general configuration information. This report is also of use when
troubleshooting system problems and can be used with the Management Agents
Home Page to resolve such system problems.
See System Administration for information on the sys_check utility,
including information on how to set up a cron task to create regularly
updated system census reports. See sys_check(8) and cron(8) for more
information.
Tru64 UNIX SysMan Home Page
This provides links to the SysMan Menu and SysMan Station for managing
Tru64 UNIX systems.
You can opt to launch the SysMan Menu or the SysMan Station. When using
Netscape, you need the Java plug-in as described in the Browser
Requirements section of this reference page.
You are prompted for the name and password of an authorized account.
Because the SysMan suite is run as a Java applet, you cannot close or
otherwise use the associated browser window. If you attempt to do this, the
Java applet also will be closed.
You also can run any SysMan task from any networked PC using a browser
without the need to install the SysMan Menu and the SysMan Station client
PC software.
Access Home Page
The Access home page provides links to related web pages including the home
page.
You can access this page by selecting the Web-Based Management banner at
the top of the Device home page.
WBEM Login Home Page
You can log in using one of three provided accounts (User, Operator, or
Administrator) and their default passwords. For more information, see the
section titled "Security" in the web based help.
To chang the default passwords, select the changed link in the following
sentence, located on the right side of the WBEM Login Home Page.
The Password for a login account may be changed at any time by an
Account Administrator.
See the following description of the Configuration Options Home Page for
important information on anonymous access.
WEBM Device Options Home Page
This web page contains options that can be set by the administrator to
control access to Insight Manager. The options are:
Anonymous Access
Enabling this option allows nonprivileged users to view devices and
device data. This option is turned on in the default configuration.
Use this option with care. Even restricted view-only access to your
computing environment might not be acceptable because it reveals
the names and network addresses of systems.
Local Access
Enabling this option allows any user with access to the local
console to perform administrative tasks. This option should be
selected with care due to the security implications. This option is
turned off by default.
Auto Delete Users
When enabled, this option deletes automatically user directories
that have not been accessed for a specified number of days. This
option is turned on and set to 30 days by default.
HTTP Auto-discovery
When enabled, the local server participates in auto-discovery of
any local hosts running the Insight Manager agent. Enter a time in
minutes to control the frequency of auto-discovery updates. Use
this option to prevent auto-discovery of inappropriate systems.
This option is turned off by default.
HTTP Auto-discovery master
When enabled, the local server participates in auto-discovery as a
potential master node. Use this option to prevent inappropriate
systems from becoming the master device in a WBEM network. This
option is turned off by default.
You can access this web page by selecting the text link, Options, on the
Device Home Page.
WEBM Active Devices home page
This web page lists all devices found in the local WBEM network when HTTP
auto discovery is enabled in the WEBM Device Options home page, including
the Insight Manager XE Servers known to the system as well as devices that
the system has detected on the network.
You can access any of the listed systems by selecting the corresponding
link. The system's device home page is displayed in the browser.
You can access this web page by selecting the text link, Devices, on the
Device Home Page.
Devices
Two devices have special status on the web-based network:
· The Windows NT server that is running the XE management console. This
system must be configured with the Insight Manager XE software, and
will enable many of the remote administrative services. The XE server
has a port address of :280, and you connect to this server from your
browser by specifying the URL as follows:
http://system_name:280
Note that a Insight Manager XE server is not necessary for peer-to-
peer administration of Tru64 UNIX systems; you can view system status
and perform administrative tasks using the SysMan Menu and the SysMan
Station in such an environment.
· The master device, which polls all other available devices for their
status and data, stores it in a master record, and makes the master
record available to any other device. This device is always the one
with the lowest local TCP/IP network address (in the format
110.222.333.110). An important consideration here is that you must
assign this number to a system that is capable of handling the WBEM
traffic. If the device with the lowest TCP/IP address becomes
unavailable for any reason, the device with the next lowest TCP/IP
address becomes the master. All other devices are slaves.
