IBM Tivoli Netcool Service Quality Manager Data Mediation Gateway Development

Chapter 3. Gateway development 47

3.1.2 GPRS Service Solution interface control guide

The version of Service Quality Manager GPRS Service Solution installed is V1.3.

This GPRS Service Solution includes several data sources for:

򐂰 Radio Access Network (RAN) PM

򐂰 Core Gateway GPRS Support Node (GGSN) PM

򐂰 Core Serving GPRS Support Node (SGSN) PM

򐂰 End-to-End (E2E) Active Test

For each data source, there is an interface control guide in a PDF file. The

interface control guide explains the input file requirements so that data can be

loaded successfully. We use the GPRS Core GGSN PM Service Solution

Interface Control Guide as a basis to develop and configure the gateway we

have.

In conjunction with the functional specification of the technology pack, we can

correlate the performance data information for the GPRS Core GGSN PM.

GPRS Core GGSN PM CSV file naming convention

The adapter in the GPRS Core GGSN PM Service Solution requires the input

CSV file to be named as follows:

AYYYYMMDD.hhmm-YYYYMMDD.hhmm_UniqueID_GGSN.csv

where YYYYMMDD.hhmm elements correspond to the file interval start time and

end time, respectively.

MsActivatedPdps MsActivatedPdps The total number of PDP context activation

procedures initiated by an MS on this APN

MsActivatedDynPdps MsActivatedDynPdps The total number of dynamic PDP context

activation procedures initiated by an MS on this

APN

NetworkInitPdps NetworkInitPdps The total number of network initiated PDP

context activation procedures

SuccMsDeactivatedPdps SuccMsDeactivatedPdps The total number of successfully completed

PDP context deactivation initiated by the MS

MsDeactivatedPdps MsDeactivatedPdps The total number of PDP context deactivation

procedures initiated by an MS on this APN

48 IBM Tivoli Netcool Service Quality Manager Data Mediation Gateway Development

UniqueID is an optional element that can be used to, for example, uniquely

identify the GPRS Core Network. In a situation where the deployed solution has

multiple mediation points, then this element is recommended.

We use a custom field in the PERLIZE rule and a modified CSV output writer to

achieve this name. This customization is explained in 3.5, “Developing the post

parser configuration for Motorola GGSN” on page 58. Example 3-1 show some of

the file names using the desired naming convention.

Example 3-1 GPRS Core GGSN CSV file naming convention

GPRS Core GGSN PM CSV file format

The content of the CSV file for the core GGSN PM is listed in Table 3-3. The

fields should be described in the CSV header lines.
