Open Source Linux Logging Software

spdlog is a header only library. Just copy the files under include to your build tree and use a C++11 compiler. It provides a python like formatting API using the bundled fmt lib. spdlog takes the "include what you need" approach, your code should include the features that actually needed. For example, if you only need rotating logger, you need to include "spdlog/sinks/rotating_file_sink.h". spdlog provides various log targets, which are, rotating log files, daily log files, console logging (colors supported), syslog, Windows event log, and Windows debugger (OutputDebugString(..)). Easily extendable with custom log targets. Log filtering, log levels can be modified in runtime as well as in compile time. Support for loading log levels from argv or from environment var. Backtrace support, store debug messages in a ring buffer and display later on demand.

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.

Chucho is a logging library for C++11. It is modeled on the popular Java library, Logback. It also exposes a C interface, so that C programs can make use of Chucho.

This project has been migrated to GitHub : https://github.com/vlachenal/anch-framework AnCH framework aims to provide utility classes for some common programming features. Features are implemented to be used as simply as possible. This framework was initially a way to test new C++ specifications (C++11) and to test C++ design patterns and tricks. Only POSIX systems are supported for now. Others could be supported later. (Partial) Doxygen documentation can be found on project home page.

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

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.

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.

Java logging can be a Kafkaesque mess of complexity that buys you little. Getting even the simplest logging working can be comically hard, and it often gets worse at scale as your needs become more sophisticated. Timbre offers an all Clojure/Script alternative that's fast, deeply flexible, easy to configure with pure Clojure data, and that just works out the box. No XML. Easily filter logging calls by any combination of: level, namespace, and appended. Zero overhead compile-time level/ns elision. Useful built-in appenders for out-the-box Clj+Cljs logging. Powerful, easy-to-configure rate limits and async logging. Logs as Clojure values (v3+). Small, simple, cross-platform codebase. 3rd-party tools, appenders, etc. No XML or properties files. A single, simple config map, and you're set. Simple, flexible fn appender model with middleware. Great performance at any scale.

Volta Log is a java library that enables you to manage the logs of your application, saving them in Cassandra within a designated structure instead of a file. As a result, it ensures faster access to logs and a more efficient management of them.

A simple C++ logging system. It is modeled loosely after log4j.

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

The pipedump forks a process and then executes the specified command, acting as a proxy for STDIN, STDOUT, and STDERR. Debug data and data sent to STDIN are recorded as a IPv6 UDP packets traversing from ::1 to ::. Data received from STDOUT and STDERR are recorded as a IPv6 UDP packets traversing from :: to ::1. STDIN is recorded as port 19840, STDOUT as port 19841, STDERR as port 19842 and debug information as port 65535. The captured data is recorded in a file which can be read by network analyzing tools capable of parsing PCAP files.
