Logbook is an extensible Java library to enable complete request and response logging for different client- and server-side technologies. It satisfies a special need by a) allowing web application developers to log any HTTP traffic that an application receives or sends b) in a way that makes it easy to persist and analyze it later. This can be useful for traditional log analysis, meeting audit requirements or investigating individual historic traffic issues. Logbook is ready to use out of the box for most common setups. Even for uncommon applications and technologies, it should be simple to implement the necessary interfaces to connect a library/framework/etc. to it.

This is a C++ logging library implementation which is accepted to Boost. It aims for extensibility and flexibility while moderately affecting user's application performance. Since being accepted, the library is developed and distributed as a part of Boost. Please, visit www.boost.org for more info.

Autologging eliminates boilerplate logging setup code and tracing code, and provides a means to separate application logging from program flow and data tracing. Autologging provides two decorators and a custom log level: "autologging.logged" decorates a class to create a __log member. By default, the logger is named for the class's containing module and name (e.g. "my.module.ClassName"). "autologging.traced" decorates a class to provide automatic CALL/RETURN tracing for all class, static, and instance methods, as well as the special __init__ method (by default) "autologging.TRACE" is a custom log level (lower than logging.DEBUG) that is registered with the Python logging module when autologging is imported

A set of advanced Log4J appenders designed for hi-load applications. Among them: TimeAndSizeRollingFileAppender, ThreadSafeAsyncAppender, DbcpDataSourceAppender, JndiDataSourceAppender etc. Also includes appender wrappers for use in JBoss environment

Another logging framework for Java. I try to balance flexibility, usabilty and performance using OOP. Currently the framework is usable but it lacks a lot of functionality.

The cpp_trace is a flexible and compact logging C++ library. The library provides a facility to filter and route between output streams text trace messages. It uses generic type-safe design and conforms to STL io stream concepts.

eClog, a PHP log class, offer ability to log to file (default), console, database, mail, error_log and syslog. Supports multiple parallel handlers and ability to trigger PHP errors. There are ongoing development on stomp, mqseries and snmp handlers.

A tiny and easy to use log library for C/C++. Written in C. Customizable log message format for global and specified output target Cross platform support. Tested: linux, win32, wince, mac
