Quick Start

NOTE:

QuickStart Introduction

The following sections outline the steps to install a typical Dell OpenManage Network Manager system and its subsequent first use. Because the software described here is both powerful and flexible, this quickstart cannot describe all the details of available installations. Instead, this Guide refers to those descriptions elsewhere or in online help. It also includes a “Pre-Flight” Checklist, below. A typical installation includes the following:

• Installing and System Startup

• Configuring Dell OpenManage Network Manager Users

• Discover Your Network

• Resource Management

• Configuration Management

• Fault Management - Problem Diagnosis

• Performance Management - Troubleshooting

•Create Reports

• Collaborative Diagnosis

Before you begin installing Dell OpenManage Network Manager, make sure your hardware and network are correctly configured. For more about that, see Getting Started on page 27 of the Dell OpenManage Network Manager User Guide

“Pre-Flight” Checklist

Installation

❑ Installation host: Log in as an administrative user. An administrative user can

write to the installation target directory. Do not log in with a user name that is Administrator on Windows XP or a name that contains spaces. Also: You must have root access to install on UNIX, but do not install as user root.

❑ Remove Firewall barriers: Remove firewall barriers between hosts and/or between

your installation and Monitored Devices. Best practice is to take down the firewall, install the application, then put it back up.

❑ Directories: The source directory should not be the same as installation target

Installing and System Startup

Initiate installation by executing through the installation wizard, accepting the license and making the appropriate entries.

During installation, one screen lets you select the application’s memory size. Best practice is to select the largest available after 1 - 4 GB is set aside for the operating system.

You can re-set the selected memory size after installation too, with the following properties in \owareapps\installprops\lib\installed.properties:

oware.server.min.heap.size=1024m

oware.server.max.heap.size=1024m

win_install.exe

(Windows), or linux_install (Linux). Click

When you have installed and successfully deployed Dell OpenManage Network Manager, you can

Configuring Dell OpenManage Network Manager Users

As an Administrator, you can configure Users, and Roles to identify support teams (examples: administration, engineering and operations) and configure permissions. After creating them, add Users to roles which configure their permissions for access and action. The following describes how to do this.

Fault Management - Problem Diagnosis

Dell OpenManage Network Manager lets you diagnose network problems with its Alarms viewer, and lets you monitor performance with its Performance Management - Troubleshooting capabilities, as described below. The following briefly outlines these capabilities

Alarms

Tip

Alerts about network performance issues can include alarms about the following:

• Excessive interface utilization

• Unexpectedly high CPU load

• Loss of available memory

• Slow response time

• Excessive interface errors

When you receive an alarm you can take any of the following action on the alarm itself, or the target of the alarm:

•Assign User

•Acknowledge Alarm

• Unacknowledge Alarm

• Clear Alarm

•Show Performance

Follow these steps to get started:

Click to go to the

In the Alarms portlet, click on an Alarm of interest.

If your Alarms portlet displays a graph of different alarm types, clicking on s particular alarm severity filters the list below to only display that severity. Click again to undo the filter effect.

where you can view more details about an alarm.

Performance Management - Troubleshooting

In addition to troubleshooting faults, you can also monitor device performance with Dell OpenManage Network Manager.

Monitors

Monitors display some critical performance metrics for devices on the network, including:

•Network availability

•Bandwidth capacity utilization

•Buffer usage and errors

•CPU and memory utilization

•Interface errors and discards

•Network latency

•Node and interface status

To get started using monitors, follow these

steps:

Click the Performance Management > Summary page, and find the Resource Monitors portlet on that page.

Hover the cursor over a Monitor of interest to see a tooltip of details about it.

Click to select a Monitor of interest.

Right-click the selected monitor in the Resource Monitors portlet, and then click edit its details, including enabling/disabling it.

Open

Dashboard Views

With permissions, you can view the performance data collected by the monitors, in graphical and tabular form including:

• Excessive interface utilization

• Unexpectedly high CPU load

• Loss of available memory

• Slow response time

• Excessive interface errors

To view this data, follow these steps:

How To:

Create Reports

If your want to automate month-end reports Dell OpenManage Network Manager lets you schedule either recurring reports or a single scheduled occurrence. With the correct permissions, you can run Inventory Reports on demand or as scheduled. You can use the Reports to troubleshoot and monitor performance and historical data that has been collected during the operation of the network.

Click the Performance Management > Summary page and find the Top Problem Nodes portlet. (

which opens a dashboard

Collaborative Diagnosis

Once Dell OpenManage Network Manager notifies you about a network problem with Fault Management - Problem Diagnosis or Create Reports, you can consult with other network experts through Dell OpenManage Network Manager’s built-in chat system. You can even meet online with more than one user, and share the problem report, or alarm. See Status Bar Alerts on page 70 and Sharing on page 82 of the Dell OpenManage Network Manager about how to do this.

Some examples of easy solutions provided by chat:

• You cannot use an FTP server. Asking a coworker with Dell OpenManage Network Manager’s chat reveals it is out of commission. Because you can share specific servers as a chat attachment, there’s never a question about which server you are discussing.

• Confirm the format of a report. Again, attaching the report to chat lets coworkers see exactly what you are talking about, and quickly.

• When a report reveals a problem, you can attach it to chat, and consult with coworkers about solutions.

• You can similarly attach schedules to chat to make sure everyone agrees they are correct.

User Guide

for the specifics

• What you can do with a single chat session is also true of Dell OpenManage Network Manager’s “conferences” which amount to collaborative chat sessions, attended by more than one other person.
