NAME
insight_manager - Web-based device status and configuration
DESCRIPTION
Insight Manager is a web-based interface that enables you to look across a
heterogeneous computing services environment and access information about
any entity connected to the network. Entities are referred to as devices
and 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.
The method used by Insight Manager to administer a computing environment is
known as web-based management (WBEM). Insight Manager protocols are able to
communicate between the following operating environments in addition to
Tru64 UNIX:
· Windows NT(TM)
· IBM OS/2
· NetWare
· OpenVMS
Insight Manager features are fully implemented in some operating
environments, but are not yet implemented in others. This means that you
can use all features of Insight Manager on Windows NT(TM) systems, but you
cannot use certain features on Tru64 UNIX. Insight Manager provides a
consistent wrapper for SysMan, enabling you to manage supported systems
from a web browser. On a Tru64 UNIX system, you can use Insight Manager to
view details of devices, but you must invoke the SysMan Menu or SysMan
Station to perform administrative tasks.
Insight Manager XE 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 Insight Manager agents.
To participate in WBEM, Insight Manager must be able to recognize its
operating environment. The operating environment must be capable of
communicating device information to the WBEM network, and also of receiving
and executing instructions sent from other (authorized) devices in the WBEM
network. The operating environments must be able to run Insight Manager
agents (daemons) which communicate with each other using a standard
protocol. Devices, and their operating environments, are able to 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 data base of objects, with attributes
and values, representing the manageable components of a device.
A feature of Insight Manager is auto discovery. Any Insight Manager agent
can discover any other Insight Manager agent in the local network domain.
The system with the lowest numerical value for its IP address is the
"master" for the subnet. You can configure a system so that it does not
participate as a master or participate in auto-discovery.
Configuration
The Insight Manager agents (daemons) are configured by default when you
install the operating system and are automatically started when the system
boots. The Web agent is initialized during transition to run level 3, and
the initialization script is located in /sbin/rc3.d/S50insightd. This
script runs /usr/share/sysman/bin/insightd and prints a boot-time message
at the console when the agent is successfully started.
The SNMP subagents /usr/sbin/os_mibs and /usr/sbin/cpq_mibs are also
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/share/sysman/bin/insightd
# ps agx | grep cpq
466 ?? S 0:00.36 /usr/sbin/cpq_mibs
# ps agx | grep os_mibs
466 ?? S 0:00.36 /usr/sbin/os_mibs
If you do not wish to have the Insight Manager Web Agent enabled by
default, you can configure its default setting through the SysMan Menu
either with the following command line utility:
# /usr/sbin/sysman imconfig
Alternatively you can use the imconfig as follows:
1. Invoke the SysMan Menu
2. Expand the Monitoring and Tuning branch to display the Set Up Insight
Manager task
3. Set up the Insight Manager task:
Enable Insight Manager
Check this box to enable access to the Insight Manager agents.
This option enables or denies access by all users, including
root.
Administrator Password and Password Verify
Supply a password for the administrator. When Insight Manager
is set up, password access can be granted to other users from
with Insight Manager itself. You can use this option to update
the administrator password at any time.
Enable anonymous logins to WebAgent Applications
Allows non-privileged users to invoke Insight Manager and view
details of any connected devices in the local area network.
Users cannot perform any operations unless authorized.
However, there are security implications in giving non-
privileged users access to Insight Manager.
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:
_____________________________________________________________________________

You must turn on the following options so that the Server Agents work
properly:
· Enable Java
· Enable JavaScript
· Accept all cookies or Accept cookies originating from the same server
as the page being viewed
Security
You can anonymously access the device web page without logging in. If
needed, the Insight Manager administrator can set user privileges and
passwords. There are only three predefined users (user, operator, and
administrator). The Insight Manager administrator can change the user
passwords via the Account Login window.
There are three types of data:
· Default (read only)
· Sets (read/write)
· Reboot (read/write).
The WEBAGENT.INI configuration file specifies the level of user that has
access to data. Please refer to the Agent Help link in the online help for
further information on setting security and on the default user, operator,
and administrator passwords.
Using Insight Manager
Connect your web browser to port 2301 on any system in the local area
network that runs the Insight Manager agents as follows:
http://bara.cu.da.com:2301
You can also specify the TCP/IP address, such as in place of the host name
and address.
http://20.111.333.10:2301
Once you have connected to a system, you can view the local system, status,
or select other hosts on the local network. You can connect to another host
simply by selecting its address from the list of local devices.
Device Home Page
On successful connection, the Insight Manager Web-based Management device
home page appears. This page provides links to other pages both in text
format, and as icons. Move the pointer to an item and press mouse button 1
(MB1) to invoke a link. Note that the UNIX 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. You can always navigate back to one of the
following three pages from any Insight Manager page:
Device Home page
Is the starting point for all other links
Configuration Options page
Enables you to configure the Insight Manager on the local host.
The following links are available from the Device Home page
·
Insight Manager page banner
·
Login Account
·
Log in as administrator
·
Refresh
·
Options
Devices page
Displays all devices found in the local WBEM network.
Online help is available for any Insight Manager 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.
Insight Manager Agents Home Page
The Insight 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 Insight Management Agents frame contains the icons and labels that
describe the status of a device and its components (if any). It also
contains several options that can be selected to display more information
in the Summary (main) frame. This frame provides the following options:
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. Refer to the online help for
more information on the configuration options.
Legend of color-coded icons that describe the device and component status.
They are:
·
Unknown (blue)
·
OK (green)
·
Degraded (yellow)
·
Failed (red).
The Navigation frame lists all the subcomponents for which data can be
obtained and any associated data items. It provides status data on
hardware, such as network interface (NIC) cards, and also data on general
system status, such as CPU utilization. The content of this frame is
dependent on what device data can be provided by the device to Insight
Manager. Typical contents for a device that is a computer system are as
follows:
Configuration
Provides information on the system type, the main CPU board and the
operating system software. You can select any of these links to
display further data in the Summary frame
Mass Storage
Provides 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 busses 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 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, and settings, and network
statistics.
Utilization
Provides information on the CPU utilization with aggregate load for
the past one, five, thirty, and sixty minutes.
Recovery
Provides 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 can also display the log of start-up messages that was saved
when the system was last booted.
The Data frame - Any links selected in the preceding frames will be
displayed here. When you first access the Insight Management Agents page,
this frame contains information which enables you to identify the device
type and model, its physical and network locations, and its general status.
Use the Summary link in the Insight Management Agents frame to display this
default information.
Devices
Two devices have special status on the WBEM 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://bara.cu.da.com:280
Note that an 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.
