 The Common Log Format (CLF) for the Session Initiation Protocol (SIP):
                    Framework and Information Model
                 draft-ietf-sipclf-problem-statement-12

Abstract

   Well-known web servers such as Apache and web proxies like Squid
   support event logging using a common log format.  The logs produced
   using these de-facto standard formats are invaluable to system
   administrators for trouble-shooting a server and tool writers to
   craft tools that mine the log files and produce reports and trends.
   Furthermore, these log files can also be used to train anomaly
   detection systems and feed events into a security event management
   system.  The Session Initiation Protocol (SIP) does not have a common
   log format, and as a result, each server supports a distinct log
   format that makes it unnecessarily complex to produce tools to do
   trend analysis and security detection.  This document describes a
   framework, including requirements and analysis of existing
   approaches, and specifies an information model for development of a
   SIP common log file format that can be used uniformly by user agents,
   proxies, registrars, redirect servers as well as back-to-back user
   agents.
