Chapter 1: Introducing the Integration

This section contains the following topics:

Overview (see page 7) Setup Time Estimates (see page 7)

Overview The eHealth Integration for Nortel Shasta SCS GGSN module (eHealth – Nortel SCS GGSN) lets you manage your Nortel wireless data services using eHealth reports. The module imports data and reports about statistics for Nortel Networks Gateway GPRS Support Node (GGSN) using the Nortel Service Creation System (SCS). The integration module is capable of supporting data from multiple systems within a wireless carrier facility and monitoring key performance indicators that help you maintain quality of service.

The Nortel SCS GGSN devices are responsible for ensuring that radio and voice wireless data services are working properly. eHealth reports provide insight into whether your Nortel wireless carrier facilities are experiencing problems that will affect your customers. The statistics that eHealth collects characterize the capacity and performance of the Nortel SCS GGSN devices. Therefore, reports about those statistics help you predict capacity issues and maintain optimal service levels. For example, you can view reports to understand if you have deployed the appropriate number of devices to support your wireless data services.

This document explains how to do the following:

■ Set up eHealth – Nortel SCS GGSN to collect configuration and statistics information from Nortel SCS GGSN servers.

■ Modify eHealth polling and import settings to obtain the element and statistics data required to generate an ideal set of eHealth reports.

■ Schedule reports for Nortel SCS GGSN network devices and gives a description of these reports.

Setup Time Estimates Time estimates for each set-up phase include the following:

■ 1 hour to verify requirements and complete the setup checklists.

■ 10 minutes to add a license.

Chapter 1: Introducing the Integration 7

Setup Time Estimates

8 User Guide

■ 1/2 hour to run the setup program.

■ 2 minutes – 7 hours to configure Nortel elements, depending on the number of elements.

It takes approximately 1.5 hours to one day to set up this integration.

Chapter 2: Setting Up the Integration


Verify Integration Requirements (see page 9) eHealth System (see page 9) Nortel SCS Servers (see page 10) Complete the Setup Checklists (see page 12) Add a License (see page 12) How to Set Up the Integration (see page 12)

Verify Integration Requirements To install and run the eHealth – Nortel SCS GGSN Integration, you must meet requirements for the following:

■ eHealth server

■ FTP

■ Time Zone

■ Nortel SCS GGSN server

Important! You must install eHealth – Nortel SCS GGSN Integration on a Solaris system.

To set up and use this integration module, you must also obtain and install an eHealth – Nortel SCS GGSN license for your eHealth systems.

Note: System requirements can be found in the eHealth Integration Modules Release Notes.

eHealth System When you install eHealth and an eHealth – Nortel SCS GGSN license, you can run the setup program from the command line. Use this setup program to specify the Nortel SCS GGSN servers from which you want to collect configuration and statistics data.

You can run the eHealth – Nortel SCS GGSN Integration setup program on multiple eHealth Solaris systems to configure each system to collect data from the same or different Nortel SCS GGSN servers. If you are running multiple eHealth systems in a Distributed environment, you can install eHealth – Nortel SCS GGSN on a Distributed eHealth System, but not on a Distributed eHealth Console.

Chapter 2: Setting Up the Integration 9

Nortel SCS Servers

Note: For information about eHealth installation requirements, see the eHealth Installation Guide. For more information about Distributed eHealth, see the Distributed eHealth Administration Guide.

FTP Requirements

eHealth – Nortel SCS GGSN Integration uses FTP to communicate with the Nortel SCS GGSN servers. The integration module supports both standard and Secure Shell (SSH) FTP.

If you use standard FTP, the setup program prompts you for a user name and password that allows access to the Nortel SCS GGSN server that you want to configure.

If you use secure FTP, the setup program does not prompt you for a password. However you must configure secure FTP on the Nortel SCS GGSN server and on the eHealth system prior to completing the eHealth – Nortel SCS GGSN Integration setup program.

Note: For more information, see the eHealth Installation Guide, which you can download from www.ca.com, or access on the eHealth TotalDoc CD. For information about setting up secure FTP on your Nortel SCS GGSN servers, see the Nortel Networks documentation.

Time Zone Requirements

The eHealth systems must be set to the same time zones as the Nortel SCS GGSN servers from which they are extracting data, otherwise the data that appears in eHealth reports will not be accurate.

Note: For more information about setting the time zone for eHealth, see the eHealth Administration Guide.

Nortel SCS Servers You can configure one or multiple Nortel SCS GGSN servers from which one or multiple eHealth systems can collect data. You must set up these servers according to instructions provided by Nortel Networks.

10 User Guide

Nortel SCS Servers

Statistics Collection

Before eHealth – Nortel SCS GGSN can extract data from the Nortel servers, the Nortel SCS GGSN administrator must set up statistics collection on each server that you configure for the integration.

Note: For information about setting up statistics collection, see the Nortel Networks documentation.

The Nortel SCS GGSN administrator must enable statistics collection for the following list of Nortel network objects. When statistics collection is enabled for all objects, you can generate complete, accurate, and useful eHealth reports. Statistics files can be generated in GMT or local time. Make sure that you set the eHealth systems to use the same time as the Nortel servers from which they collect data. We recommend that the administrator set the statistics collection interval to 30 minutes and turn on accounting profiles for the following supported Nortel SCS GGSN objects.

Statistics are collected from the following accounting groups. The indented text represents a child element of the parent element.

■ GGSN

■ GnISP (includes GTP Protocol and CGF elements)

■ GGSN UMTS Qos

– GGSN QoS traffic classes (including four sub classes: Conversational, Streaming, Interactive, and Background)

■ CPU

■ GiISP Comm

– APN

– Local Address Pool

– VRF

■ GiISP Servers

– Radius Server

– SCP Server

– DCC Server

– DHCP Server

After eHealth imports this information, it creates an element for each Nortel object and stores information in the eHealth database. The statistics collected provide information about the capacity and performance of the Nortel objects. This information is used in eHealth reports, which you can run after you complete the integration module setup process.

6. Enter q when you complete your changes.

You exit the program.

Importation of Nortel SCS GGSN Data

After you complete the initial setup of the integration module, you must import configuration and statistics data from the Nortel SCS GGSN servers. When eHealth imports this data, it creates elements that represent the Nortel SCS GGSN objects from which it imports data. Before you import data, review the following options and do one of the following:

■ Import all data without dividing it into groups.

■ Create a rules file that defines how you want to group your elements, then apply this file to the import process.

Import Data Without Grouping Elements

To import Nortel SCS GGSN data and update the eHealth poller configuration without grouping elements, enter the basic form of the nhNortelScsGgsnGetCfg command as follows:

nhNortelScsGgsnGetCfg



You can run this command manually, or schedule it to run automatically at intervals that you choose. Each time the import process runs, this command not only adds new elements to the eHealth database, but also updates information on existing elements.

How to Import Data and Group Elements

When you have a large number of elements, you can enable the import process to group elements automatically every time it runs. Otherwise, you have to group the elements manually each time the import process completes.

To group elements during the import process, you must complete the following steps:

1. Create rules files that define your grouping strategy.

2. Run the nhConfig command to apply the rules files to the import process.

Create a Rules File

When grouping elements, you must define a strategy and create a rules file.

To view Nortel elements and plan your grouping strategy

1. Run the following command which generates a Data Configuration Import (DCI) file for each Nortel server that you configured:

nhNortelScsGgsnGetCfg -verify

Each DCI file displays the Nortel elements associated with a particular server. The -verify option collects element data from each Nortel SCS GGSN server, but does not commit it to the eHealth database or record that the data was imported.

2. Use this command to place the data in separate files for each Nortel server into the following path:

$NH_HOME/modules/nortelScsGgsn/NoCommit

.nhiNortelScsGgsnConfig/hostname/config.dci

hostname

Displays the name of the Nortel server from which the information was extracted.

3. Review the contents of each DCI file, looking for patterns. For example, you might want to group all elements that have a common string. Or, you might want to exclude elements that you intend to add to another eHealth system.

18 User Guide


4. Create a rules file that describes the patterns that you want to use for grouping and reporting. The rules file instructs the eHealth system to group, exclude, or rename Nortel elements before saving them in the eHealth database.

You can create multiple rules files, each designed to process element information in different ways, and apply them at different times, based on your reporting needs. Your eHealth reports use the specified groupings, exclusions, and element names. A well-designed rules file lets you produce reports that meet your needs.

5. Note the directory and pathname where you save the rules files. You will need to specify them when you apply rules files to the import process.

Note: For more information about how to create rules files, see the eHealth Data Integration Guide.

Apply Rules Files to the Import Process

After you create rules, you must apply them to the import process to enable them.

To apply rules

1. Run the following command for each set of Nortel elements to which you want to apply rules:

nhConfig -dciIn hostname.dci

-dciRule rulesFile.dcr

hostname

Identifies the server’s DCI file that you want to apply the rules file to, and rulesFile is the name of the new DCI rules file that you just created.

2. Specify the full pathname where each file is saved if you are not running the command in the same directory where you saved the rules file and the .dci file.

When eHealth imports configuration data and adds elements for Nortel objects to the database, eHealthbegins to collect statistics data automatically.

How to Schedule The Import Process

You can schedule the import process to run automatically as an option.

To schedule the import process, follow these steps:

1. Use the nhSchedule command to specify the new job type (import process) and the command to collect element information.



20 User Guide

Examples:

■ To create a job type named Nortel Config that uses 100 percent of the system resources, and executes the command nhNortelScsGgsnGetCfg when it runs, you would use this command:

nhSchedule -defineType "Nortel Config"

-load 100 -cmd "nhNortelScsGgsnGetCfg"

■ To schedule the Nortel import process to extract configuration information every day at 12:30 A.M., you would use this command:

nhSchedule -schedule "Nortel Config"

-time "12:30 AM" -daily yyyyyyy

-args "-dciRule rulesFileName"

rulesFileName

Specifies the name of your DCI rules file. This argument is optional.

2. Specify a time and frequency that correspond to the frequency with which changes are made in your network. For example, if assignments change daily, schedule the import process to run daily. If you schedule several import processes, schedule enough time between them so that one completes before the next one starts.

Note: For more information about the nhSchedule command, see the eHealth Administration Guide and the eHealth Command and Environment Variables Reference Guide.

Modify Data After it Has Been Imported

You can use the Poller Configuration dialog on the eHealth console to modify Nortel element information that resides in the eHealth database. Any changes, other than element name changes, will be overwritten the next time the nhNortelScsGgsnGetCfg command runs and imports configuration information.

Important! Do not change the agent type for Nortel elements. If you do, eHealth will not poll those objects.

Whenever you delete elements from a Nortel SCS GGSN server, you must also delete those elements from the eHealth database using the Poller Configuration dialog.

When you disable polling for certain Nortel elements, you can continue to run reports about them using previously collected data.

Note: For information about using the Poller Configuration dialog, see the eHealth Online Help and the eHealth Administration Guide.

Chapter 3: Reports


eHealth Reports for Nortel GGSN Objects (see page 21) Trend Reports (see page 21) Top N Reports (see page 22) At-a-Glance Report (see page 23)

eHealth Reports for Nortel GGSN Objects Once eHealth – Nortel SCS GGSN begins collecting data from Nortel SCS GGSN servers, eHealth maps statistics for Nortel objects to eHealth reporting variables. This lets you generate a set of reports that gives insight as to how your network performs under varying load conditions and whether your resources are optimized.

eHealth reports let you monitor the performance of Nortel GGSN objects in your mobile internet protocol (IP) networks and helps you identify problem areas before they impact your business.

Note: Before running reports for the first time, let the import process complete at least once to show all element data in your reports.

eHealth – Nortel SCS GGSN supports the following eHealth reports:

■ Top N

■ Trend

■ At-a-Glance

Trend Reports Trend reports provide summaries about a device and any or all of its elements. You can generate a Trend report for up to 10 variables for one element, or for one variable for up to 10 elements. Using a Trend report you can identify the best or worst performers of all of the elements on a switch, or you can identify busy or peak usage times on a switch. With this information you can target the times of day that you should monitor key performance indicators and examine usage trends.

Chapter 3: Reports 21

Top N Reports

The following is an example of a Trend report:

Top N Reports Top N reports show a chosen performance variable across all elements, the top performing elements, or only those elements that meet a certain criteria. This kind of report helps you determine which elements are the highest and lowest performers for key indicators, such as bandwidth utilization, availability, or errors. Once you identify a high or low performer, you can get a better view of key performance indicators on that element using an At-a-Glance report.

22 User Guide

At-a-Glance Report

The following is an example of a Top N report:

At-a-Glance Report At-a-Glance reports are summaries of key performance indicators for a chosen element. They let you examine several parameters at the same time to identify the source of a problem.

For example, once a Top N report shows you that the total number of bytes on a port is extremely low, you can drill down to an At-a-Glance report that shows you all of the performance indicators on that port. This can help you identify the source of the poor performance.

For more information about running reports, see the eHealth Reports User and Administration Guide and the eHealth Online Help.
