insight_manager - Web-based device status and configuration
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 [Toc] [Back]
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 boottime
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 [Toc] [Back]
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 inclu- Netscape Communicator 4.06 or
sive higher
Windows 95, Windows 98, or Windows NT Microsoft Internet Explorer version
3.51/4.0 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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
Successfully connecting to port 2301 displays the Webbased
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 [Toc] [Back]
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: 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: Invokes the web-based help page
Returns to the Summary (main) frame Returns to the Device
Home page Enables you to configure the presentation of
device data, and set values such as the refresh interval
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: Provides links to information on the system
type, the main CPU board, and the operating system software.
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. 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.
Provides links to information on the CPU utilization with
aggregate load for the past 1, 5, 30, and 60 minutes.
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. 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 webbased
documentation to provide you with more information
on all the Insight Manager pages.
Tru64 UNIX Configuration Report Home Page [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
This web page contains options that can be set by the
administrator to control access to Insight Manager. The
options are: 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.
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. 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. 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. 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 [Toc] [Back]
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 [Toc] [Back]
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.
