RFC6872 - The Common Log Format (CLF) for the Session Initiation Protocol (SIP): Framework and Information Model

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 troubleshooting 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, and redirect servers as well as back-to-back user agents.

RFC6873 - Format for the Session Initiation Protocol (SIP) Common Log Format (CLF)

The SIPCLF working group has defined a Common Log Format (CLF) framework for Session Initiation Protocol (SIP) servers. This CLF mimics the successful event logging format found in well-known web servers like Apache and web proxies like Squid. This document proposes an indexed text encoding format for the SIP CLF that retains the key advantages of a text-based format while significantly increasing processing performance over a purely text-based implementation. This file format adheres to the SIP CLF information model and provides an effective encoding scheme for all mandatory and optional fields that appear in a SIP CLF record.
