Open Source Windows Logging Software

log4cplus is a simple to use C++ logging API providing thread-safe, flexible, and arbitrarily granular control over log management and configuration. It is modelled after the Java log4j API.

A library of C++ classes for flexible logging to files (rolling), syslog, IDSA and other destinations. It is modeled after the Log for Java library (http://www.log4j.org), staying as close to their API as is reasonable. Home: https://log4cpp.sourceforge.net Platforms: Linux, Windows, MacOS. New: CMake, CTest support for MS VS 2022, RAD Studio 12

Logrus is a structured, pluggable logger for Go (golang) that is completely API compatible with the standard library logger. It encourages careful, structured logging through much more discoverable logging fields rather than long, unparseable error messages. This produces much more useful logging messages. Logrus is currently in maintenance mode, which means that new features will no longer be introduced. This does not mean however, that it is dead. It continues to be maintained for security, backwards compatibility and performance, so you can still rely on it for structured logging in Golang. Please take note however, that everything using Logrus will need to use lower-case so as to avoid casing issues.

File system/directory monitoring utilities with loggin and task processing support (can execute files or make a WCF service call). Multiple configuration options. Source code libraries can be used to create a custom file system monitor.

Beautiful, fast, and open-source viewer for your app logs. Forget scrolling through raw log files to find the errors or debug logs you're looking for. Forget about SSH'ing onto the production server just to read the logs. Log Viewer helps you quickly and clearly see individual log entries, to search, filter, and make sense of your Laravel logs fast. It is free and easy to install.

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.

Lumbermill is a visual log processing and distribution center for Log4j and (in 2.0) java.util.logging (JSR47). It is a Swing/GUI standalone application that supports viewing and archiving of log events.

Extract internal monitoring data from application logs for collection in a time-series database. mtail is a tool for extracting metrics from application logs to be exported into a timeseries database or timeseries calculator for alerting and dashboarding. It fills a monitoring niche by being the glue between applications that do not export their own internal state (other than via logs) and existing monitoring systems, such that system operators do not need to patch those applications to instrument them or writing custom extraction code for every such application. The extraction is controlled by mtail programs which define patterns and actions. Metrics are exported for scraping by a collector as JSON or Prometheus format over HTTP, or can be periodically sent to a collectd, StatsD, or Graphite collector socket. Precompiled binaries for released versions are available in the Releases page on Github. Using the latest production release binary is the recommended way of installing mtail.

Allows you to redirect all communication data from RS232 compliant serial port device into a text file for further analysis. RS232 Data Logger redirects data from any available serial port/ports and works under Virtual Machine.

SysTools is a library of utility routines & classes for Borland Delphi, C++Builder, & environments that support COM. It includes 1-D & 2-D bar codes, sorting, money routines, logging, high-precision math, a run-time math expression analyzer, & much more.

Lilith is a logging and access event viewer for Logback, log4j & java.util.logging. It has features comparable to Chainsaw for log4j. This means that it can receive logging events from remote applications using Logback as their logging backend

CTrace is a multi-threaded trace debug library written in C. It provides a simple, fast, well documented trace utility for applications and as such is especially suitable for use in real-time embedded applications.

Chainsaw is a GUI log viewer and filter for the Log4J package. It listens for LoggingEvent objects sent using the SocketAppender and displays them in a table. The events can be filtered based on Priority, Thread name, Category name and Message. It can als

cross platform logging module for Python with a C interface

Non-stealth keylogger for Windows. Records mouse and keyboard (precision~10-15ms), log of events (disk size~2.5k/s) + log of operations (~ 0.2k/s). Standalone, with local copy of Python: unzip to install, delete to uninstall.NEW: hidden/visible icon

Monitors several server logs at real-time simultaneously all in one tool. The viewer updates and scrolls automatically when the log file changes... a MUST HAVE utility tool for developers. Visit http://tracelog.sourceforge.net for more information.

Windows Tail is a Windows version of Unix and Linux tail command. Tail for Windows. I wanted to make it easier to use tail in the windows environment. You can even add it to the open with dialog in windows explorer. This is great tool if you need to monitor log files. Now: Create Application Alerts! Email Alerts and SMS Alerts using SMTP! Record Tail Session to log a File! Saves location of tailed or viewed files! Works on Linux Systems using Mono! and much much more! The source code is now located in the svn repository https://svn.code.sf.net/p/windowstail/code/trunk. PS. .net 4 is required.

logview4net is a log viewer/log monitor for data created by various sources. It can listen to UDP, tail a file, tail a SQL table, monitor the eventlog and watch RSS and Atom feeds. It requires the Microsoft .NET Framework 2.0

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.

"Java log viewer" is a GUI to easily view the java application logs generated by the "java.util.logging" package. The log must be formatted by the XMLFormatter class. It provides facilities in order to filter, to sort and to find log records.

Log4net has moved to http://logging.apache.org/log4net. The .NET implementation of the popular log4j Java API providing flexible and arbitrarily granular control over log management and configuration.

A Ruby file parser/interpreter/preprocessor that comments lines of code based on conditions at the time the file is required. Very handy to implement debugging logs and code that has to be commented (not just dynamically switched off).

Microlog is a small, yet powerful logging library for mobile devices based on the Log4j API. Supports Java ME (J2ME) and Android. Logs to device, to PC or to servers online. Used in all phases from development on emulator/device to outdoor field-testing.

The goal of this project is to develop the OS-independent, obtrusive, customizable, extensible, generic logging and tracing software mechanism.

Allows JDBC resources to be monitored. You can see when java.sql objects are being opened and closed and can see the line of code where a resource that is still open was originally opened.
