1 Introduction

This document describes the measurements performed by Diameter CC.

The measurement data collected for the Diameter CC measurements are:

Streamed (if related Diameter CC service is enabled) towards a target server for runtime representation (for instance by using the dashboard utility) or dumped for post processing (for instance by using the listener and drawer tool combination). See for more information the help of related utilities delivered through the C-Diameter Toolkit which deployment is described in the C-Diameter Integration Description document.
Reported towards the CoreMW Performance Management (CoreMW/PM) service of CBA which in order can dump 3GPP compliant XML reports and provide real-time measurement inspection capabilities through NBI. This service is only valid in case of C-Diameter. That is, when Diameter CC is used in combination with the DiameterCmwAL.

The naming and representation of Diameter CC measurements is 3GPP TS 32.401 compliant. The information in this document for each measurement is following the 3GPP standard defined terminologies.

4 Measurement Loading for C-Diameter

All the above defined measurements are automatically loaded by C-Diameter into the related NBI model fragment of CoreMW/PM.

A default PmJob object instance, called CDiameterJob (DN = "pmJobId=CDiameterJob,CmwPmpmId=1"), holding all the Diameter measurement types is defined and loaded as well during C-Diameter deployment. However, this PmJob is disabled by default. C-Diameter user Applications might decide to enable this PmJob or define their own ones using the NBI.
