Why Dell OpenManage Network Manager? | Preface 9
Preface
Dell OpenManage Network Manager can give you automated, consolidated configuration and
control of your network’s resources. It is customizable, unifying multiple systems while still
communicating with other software systems (like billing) in generic WSDL, XML and SOAP.
OpenManage Network Manager’s
Administration Section describes security and some of the
runtime features supporting these applications. The OpenManage Network Manager
Administration Section of the User Guide and
Administration Section discuss licensing. Consult
Release Notes for information about changes not covered in this
Synergy User Guide .
Why Dell OpenManage Network Manager?
Dell OpenManage Network Manager’s benefits:
Productive
Discovery and wizard-driven configuration features within minutes of installing Dell OpenManage
Network Manager, you can monitor your network.
Easy
Dell OpenManage Network Manager provides the network information you need, and offers
advanced capabilities with minimal configuration overhead.
Valuable
Dell OpenManage Network Manager often costs less to use and maintain than most other
solutions.
Scalability
You can scale Dell OpenManage Network Manager to almost any size.
Key Features
The following are some key features of Dell OpenManage Network Manager:
Customizable and Flexible Web Portal
You can customize the web portal, even providing custom designed views of your data assigned to
individual users. You can even create web portal accounts for departments, geographic areas, or
other criteria.

10 Why Dell OpenManage Network Manager? | Preface
Automate and Schedule Device Discovery
Device discovery populates Dell OpenManage Network Manager’s database and begins network
analysis. You can also create network discovery schedules to automatically run Discovery whenever
you need them.
Dell OpenManage Network Manager Administration
You can now conduct administrative tasks—adding devices, user accounts, and web portal
displays—from a secure console on your network.
Open Integration
Dell OpenManage Network Manager supports industry standards. It comes with an open-source
MySQL database. It also uses industry-standard MIBs and protocols, and even lets you install open-
source screen elements like Google gadgets to the web portal.
Topology
The OpenManage Network Manager topology screen lets you create multi-layered, fully
customizable, web-based maps of your network to track devices wherever they are in your network.
Alarms
You can configure custom alarms to respond to hundreds of possible network scenarios, including
multiple condition checks. Dell OpenManage Network Manager’s alarms help you recognize issues
before your network users experience productivity losses. Alarms can also trigger actions like email,
executing Perl
®
scripts, paging, SNMP traps, Syslog messaging, and external application execution.
Traps and Syslog
Dell OpenManage Network Manager lets you investigate network issues with traps and Syslog
messages. You can use Dell OpenManage Network Manager to set up events / alarms and then
receive, process, forward, and send syslog and trap messages.
Reports and Graphs
Dell OpenManage Network Manager comes with many pre-configured reports and graphs to
display data from its database. You can archive and compare reports, or automate creating them
with Dell OpenManage Network Manager’s scheduler.
Modularity
With additional modules, Dell OpenManage Network Manager can analyze network traffic,
manage services and IP address and subnet allocations. OpenManage Network Manager modules
save time adding to existing Dell OpenManage Network Manager deployments to add feature
functionality without requiring additional standalone software.

Why Dell OpenManage Network Manager? | Preface 11
Networks with Dell OpenManage Network Manager
The beginning of network management with Dell OpenManage Network Manager is Discovery
Profiles of the resources on a network. After that occurs, you can configure Visualize (topology
views), Resource Monitors and Performance Dashboards.
Once you have done these initial steps, Dell OpenManage Network Manager helps you understand
and troubleshoot your network. For example: Suppose a OpenManage Network Manager
Performance Dashboard displays something you want to troubleshoot. You can right-click the
impacted device in the Visualize topology view to access configuration and actions. The color of
the icon in this view indicates the highest severity alarm on the device or its sub-components. For
example, red indicates a
Critical alarm.
Displays include right-click access to the Details screen (see Equipment Details on page 178),
where you can examine each section of device information and right-click to see further applicable
actions. For example right-click to Show Performance, and edit and/or save that view of
performance as another Performance Dashboard. Performance can also display portlets that Show
Top Talkers (the busiest devices) or Show Key Metrics.
From looking at Performance Dashboards or Top [Asset] Monitors you may conclude some
configuration changes made memory consumption spike. Right-click to access resource actions
under File Management that let you see the current configuration files on devices, and compare
current to previous. You can also back up devices (see Backup Configurations on page 225) and
restore previously backed up files (see Restore Configurations on page 227). Finally, you may simply
want to Resync (another right-click menu item) to insure the device and your management system
are up-to-date.
Tip
Alternatively, the Alarms portlet also lets you right-click to expose Alarm Actions.
You can right click for Direct Access – Telnet or Direct Access – MIB Browser to display a command
line telnetting to the device, or an SNMP MIB browser to examine SNMP possibilities for it.
The Managed Resources portlet can display the anatomy of a Resource with its right-click actions
(see Equipment Details on page 178). Click the plus in the upper right corner to see Managed
Resources Expanded. This displays detail or “Snap-in” panels with additional information about a
selected resource.
Reports let you take snapshots of network conditions to aid in analysis of trends, and Audit Trail
Portlets track message traffic between Dell OpenManage Network Manager and devices.
Additional Products
The following describes how to increase the power of your Dell OpenManage Network Manager
installation. While the documents mentioned above describe everything available with Dell
OpenManage Network Manager, your installation may provide only a limited subset of those
features.

12 Why Dell OpenManage Network Manager? | Preface
Updating Your License
If you have a limited license — for example OpenManage Network Manager may limit discovery to
a certain number of devices— then your application does not function outside those licensed
limits.
You can purchase additional capabilities, and can update your license for OpenManage Network
Manager by putting the updated license file in a convenient directory. Then click
License
Management
in the Quick Navigation portlet item to open a screen with a button leading to a file
browser (
Register License: Select File ). Locate the license file, and click the Register License
button. Your updated license should be visible in the License Viewer (See License Viewer on page
63
for details.)
NOTE:
If you update your installation from a previous one where you upgraded license, you must also re-
register those licenses.
You must restart application server or wait up to 15 minutes before a license modification takes
effect. (see Installation and Startup on page 28). Licenses now support three expiration formats:
Never, Date certain, and a format that indicates the license will be valid for a number of days after
registration.
Online Help / Filter
Access general online help by clicking Help in the The Dock at the top of the screen. Help
appropriate to each portlet appears when you click question mark icon on the portlet title bar.
By default, this opens a separate browser window which is not necessarily always in front of the
screen that calls it. Because it is separate, you can arrange the display so the help screen does not
conceal the portlet it describes. Click the
Show button to display the contents, index and search
tabs (
Hide conceals them again), and the Prev / Next buttons, or clicking table of contents topics
moves to different topics within the helpset.
Tip
Sometimes your browser’s cache may interfere with help’s correct appearance. If you see a table of
contents node without contents, you can often repair it by refreshing the panel or whole screen.
How To:
Use “How To”
Several sections of what follows contain the “How to” instructions for use. These are typically steps
to follow to produce the desired result. For a look at all such steps available, refer to the
How to
section of the Index.

s , or a Problem, in the screen that appears next, then click Send.
Dorado Software responds, and often uses customer suggestions in future versions of the software.
A Note About Performance
Dell OpenManage Network Manager is designed to help you manage your network with alacrity.
Unfortunately, the devices managed or the networks that communicate with those devices are not
always as fast as this software. If discovery takes a long time (it can), often network and device
latency is the culprit. You can also optimize installations to be faster (see the recommendations in
the Administration Section of the User Guide and
Administration Section s), and limit device
queries with filters, but device and network latency limit how quickly your system can respond.
Tip
If you use management systems other than this one, you must perform a device level resync before
performing configuration actions. Best practice is to use a single management tool whenever possible.

Getting Started with Dell OpenManage
Network Manager
Overview
This chapter describes how to install and start Dell OpenManage Network Manager for basic
network monitoring and management. For more detailed descriptions of all this software’s features,
consult its other manuals (the OpenManage Network Manager Administration Section of the User
Guide,
Synergy User Guide , Administration Section and User Guide ) or the online help.
Tip
If you want to find something but are unsure about which manual it is in, you can search all text in the
Acrobat files in a single directory. You can also click on the blue cross-references to go to the target
destination of cross-references in Acrobat, however for such electronic cross-references to the other
documents to work, they must be in the same directory. Cross-document links do not work between
documents for different versions of this software, but may provide an approximate location to consult.
If you are sure your hardware, software and network is correct and just want to get started
immediately, go to Getting Started on page 27.
The Dell OpenManage Network Manager portal delivers powerful solutions to network problems,
and, in addition to the OpenManage Network Manager technology documented in the following
pages, Dell OpenManage Network Manager offers the following capabilities:
• Message Boards, Blogs, Wikis
• Shared Calendars
• Enterprise Chat / Messaging
• RSS Feeds
• Tagging, Ratings, Comments
The section Server on page 49 describes how to set up some of these features.
System Basics
System requirements depend on how you use the application and the operational environment.
Your specific network and devices may require something different from the recommendations for
typical installations.

16 Overview | Getting Started with Dell OpenManage Network Manager
Generally, base the minimum configuration of any system on its expected peak load. Your
installation should spend 95% of its time idle and 5% of its time trying to keep pace with the
resource demands.
Upgrading from a Previous Version
When you upgrade your OpenManage Network Manager installation from a previous version, keep
the following in mind:
• Upgrading requires a new license to activate new features.
• Performance capabilities have been completely reconfigured. When upgrading from previous
versions, you must (re-)create dashboards from scratch.
• The following require manual migration (export, then import) from previous versions: SMTP
settings. Some scheduled items.
• You must re-create topologies as Visualizations. (suggestion: take a screenshot)
• Group Operations have been deprecated, replaced by Adaptive CLIs.
• Command monitors must be recreated, and monitors must be re-configured to monitor
Adaptive CLIs that run external scripts.
• User Names / Passwords, and User Groups (Roles) are not automatically reassigned and must
be created manually.
Supported Operating System Versions
The following are supported operating system versions:
Microsoft Windows —The supported operating systems are: Windows 2003 (Standard,Enterprise
and Web) and Windows Server 2008 (including R2 and Enterprise Edition). This is a 64-bit
application, it has been tested for Windows on 64-bit operating system versions.
NOTE:
Windows Terminal Server is not supported. The installer becomes non-responsive with Data Execution
Prevention enabled. This option is disabled by default on Windows Server 2008, but is enabled on a
Windows Server 2008 machine running Terminal Server.
• You must disable User Account Control if you are installing Windows Server 2008.
Alternatively, you can run application server as service. Another option is to run as
administrator on startappserver. In Vista, right click the startappserver icon and select run as
administrator.
• Installer may halt when pre-existing bash sessions or cmd sessions are left open. Close all such
sessions.
Linux —This application supports Red Hat (Enterprise version 5.5 or 6.0) Linux, 64-bit only. (See
32-bit Linux Libraries on page 18 for additional requirements)
CAUTION:
For Linux, you must install no more than a single instance of MySQL—the one installed with this
software. Before you install, remove any MySQL if it exists on your Linux machine.

Overview | Getting Started with Dell OpenManage Network Manager 17
Linux Installation Best Practices
How you install Linux has an impact on Dell OpenManage Network Manager’s installation. Here
are some tested best practices:
• You can install Linux in its Desktop option, or if you select Basic Server (default) - choose
additional packages: XWindows, Basic / Core Gnome Desktop without Gnome utilities,
although we suspect any Gnome will work).
• Turn off SE Linux in /etc/selinux/config. Change SELINUX=disabled. This typically requires
a reboot.
• You must install compatibility library from installation media (so it is compatible with
installation)
compat-libstdc++-33.x86_64 3.2.3-69.el6 @InstallMedia.
Also: verify that /etc/hosts points to new name-use the following command and you
should see similar output.
[qa@rh6Test Desktop]$ cat /etc/hosts
10.18.0.241rh6Test.localrh6Test# Added by NetworkManager
127.0.0.1localhost.localdomainlocalhost
::1 rh6Test.localrh6Testlocalhost6.localdomain6localhost6
Upgrading on Linux
The following are best practices for upgrading from a previous OpenManage Network Manager
version on a Linux machine:
1 Make sure Red Hat is not installed with a MySql database option (or remove the Linux MySql
first).
2 Ensure you have installed the 32-bit Linux Libraries, as described below.
3 Verify your previous version’s installation application server starts without excpetions
4 Back up the database, and any other resources that need manual installation. Consult Release
notes for a list of these.
5 Proceed with the upgrade.
Disable Firewalls
System->Administration->Firewall - You may be prompted to enter the root password; the
password dialog may be hidden behind the Firewall Configuration Startup dialog.
Directories and Permissions
Create the directory for the installation:
1 Open a terminal.
2 Change to Super User: su <enter> password: []
3 Create directory and configure its ownership and permissions:

18 Overview | Getting Started with Dell OpenManage Network Manager
mkdir /opt/
chown [your login name] /opt/[your installation directory]
chmod 775 /opt/[your installation directory]
NOTE:
[your login name] is the original non-root user available when you imported the machine. Replace [your
login name] with whichever user you are logged in as or will be installing as.
You may need to change the permissions on the installer in our package in order to give it execute
rights. If you have used the shared folder method from above, you can give the Linux installer
rights as follows:
chmod uga+x /[Install Media Path]/install/linux_install
Make sure that there is no other my.cnf file under the /etc directory. If there is, do the following:
mv /etc/my.cnf /etc/my.cnf.original
32-bit Linux Libraries
For Red Hat Enterprise 64 bit installations, you must identify the appropriate package containing
32-bit libtcl8.4.so (for the example below: tcl-8.4.13-3.fc6.i386.rpm for Red Hat).
NOTE:
Do not use any x86_x64 rpms; these would not install the 32-bit libraries.
Any 32-bit tcl rpm that is of version 8.4 and provides libtcl8.4.so works. You can download them
from Sourceforge:
sourceforge.net . Download these, then issue the command:
rpm -ivh --force tcl-8.4.13-3.fc6.i386.rpm
This forces the installation of the 32-bit libraries on a 64-bit system. Ensure that your expect
executable in your installation directory is properly linked by issuing the following commands:
[someone@RHEL5-64bit ~]$ which expect
/opt/dorado/oware3rd/expect/linux/bin/expect
[someone@RHEL5-64bit ~]$ ldd /opt/dorado/oware3rd/expect/linux/bin/expect
linux-gate.so.1 => (0xffffe000)
libexpect5.38.so => /opt/dorado/oware3rd/expect/linux/bin/
libexpect5.38.so (0xf7fd2000)
libtcl8.4.so => /usr/lib/libtcl8.4.so (0x0094c000)
libdl.so.2 => /lib/libdl.so.2 (0x0033e000)
libm.so.6 => /lib/libm.so.6 (0x00315000)
libutil.so.1 => /lib/libutil.so.1 (0x00b8d000)
libc.so.6 => /lib/libc.so.6 (0x001ba000)
/lib/ld-linux.so.2 (0x0019d000)

Overview | Getting Started with Dell OpenManage Network Manager 19
Make sure that libtcl8.4.so maps to /lib/libtcl8.4.so An Alternative for Red Hat
Linux:
1 Copy /usr/lib/libtcl8.4.so from a 32-bit RH system to /usr/local/lib/32bit
on your 64-bit Red Hat system
2 As root, execute: ln –s /usr/local/lib/32bit/libtcl8.4.so /usr/lib/
libtcl8.4.so
Supported Web Browsers
Supported web browsers include:
• Chrome (v 6 and above)
• Safari (v 5 and above)
• Firefox (v 3.6 and above)
• Internet Explorer (v 9 and above)
Screen resolution should equal or exceed 1280 x N pixels. Users running Safari on an Apple
machine must modify Java preference to run applets as their own process. Java Preferences are
under Applications > Utilities on OSX.
NOTE:
Internet Explorer versions 8 and older display alignment issues, have slower JavaScript and Flash
processing, and some transparencies do not work. Other anomalies include non-rounded corners, no
alpha rendering, scroll bars in performance indicators, non-working multi-level menus, a too-large OS
Images schedule form, and others. To fix these anomalies, install the Chrome plug-in at code.google.com/
chrome/chromeframe/. After it installs, close IE and re-open it. The look and feel should improve.
Tip
You can often resolve problems by refreshing the browser’s display.
CAUTION:
Opening Dell OpenManage Network Manager, or links originating within it in multiple tabs on multi-tab
browsers is not supported. To see “multiple” screens, configure Dell OpenManage Network Manager’s
Menu Bar.
You can download and install updates if your browser or version varies from those supported. To
have all Dell OpenManage Network Manager functionality, you must also install the latest version
of Java (v.1.6 or later) Adobe’s Flash and Adobe’s Acrobat that works with these browsers. Flash for

20 Single Server Sizing | Getting Started with Dell OpenManage Network Manager
64-bit browsers is currently a preliminary version, but you can typically run a 32-bit browser even in
a 64-bit operating system, so Flash features will still be available even if you do not want to run
Adobe’s beta software.
NOTE:
If Flash is installed, but the screen still requests it, reload the page in the browser. Also: Your screen must
be at least 1250 pixels wide.
Tip
When no cursor or focus is onscreen, some browsers interpret backspace as the Previous button.
Single Server Sizing
The following describes hardware and sizing configuration for common Dell OpenManage
Network Manager deployments. Before any deployment, administrators should review and
understand the different deployment options and requirements. Consider future growth of the
network when estimating hardware sizing. You can generally expand modern systems running Dell
OpenManage Network Manager by adding more RAM to the host server(s). Selecting expandable
hardware may also be critical to future growth. For ease of management, deployments selection
best practice is to use the fewest possible servers. Standalone (single server) deployment offer the
simplest and easiest management solution. Where high availability (HA) is required, you can
produce the simplest deployment with as few as two servers.
Minimum Hardware
The minimum hardware specification describes what Dell OpenManage Network Manager needs
at a minimum. In such minimum installations, traffic flowing from the network to OpenManage
Network Manager may exceed the capacity of the hardware. When estimating the size of a
deployment, it is important to understand the applications configurations in the target
environment. Applications that are typically the most demanding of resources are Traffic Flow
Analyzer (TFA), Event Management and Performance Monitoring.
REQUIRED Minimum hardware —6GB RAM, dual core CPU, 200 GB 7200 RPM Disk.
Supports :
• Standalone installations (Single Server) is supported when high-resource demand
applications are used minimally.
RECOMMENDED Minimum hardware: 8GB RAM, quad core CPU, 400 GB 10,000 RPM Disk
Supports:
• Standalone installations (non-distributed).
