Open Source Java Logging Software

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.

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

"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.

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.

LOG4PLSQL is a PLSQL framework for logging in all PLSQL code this project was born from the log4J spirit (and use it). You have the possibility to log apart from transaction and use all LOG4J feature.

The ProM Import Framework allows to extract process enactment event logs from a set of information systems. These can be exported in the MXML format, which is the standard event log data format for Process Mining analysis techniques.

This is my collection of Java classes. Major chunks include: robust logging system, JDBC connection pools, lightweight application server, general utility classes.... enjoy.

Follow is a simple Java application which allows a user to monitor several log files concurrently. The source for this project is now being maintained at http://hallwaytech.github.com/follow

MakeLogic Tail is an advanced "tail -f" command with GUI. It needs JRE 5.0, hence it is 'Tail for Windows', Linux or 'Tail for Mac'. It shows the last few lines of a growing log file in real time. Provides many more easy to use features. Try it!

ALF, The Automated Logging Framework, is a native logging framework for Java with the unique advantage of supporting automated method tracing. This platform-independent library allows developers to debug their applications quickly without adding code

Ajax is an open-source Java add-on collection mostly for classic desktop apps sporting new widgets (such as such as auto-complete textboxes or tree tables), new data models (such as as XML tree models), new common dialogs and much more.

Analog4J is a tool for analysing Logginginformation. Loginfo can come from files or via online sources like sockets (like log4J SocketAppenders). Loginfo can be displayed, filtered and is prepared in statistics (events per time, etc.)

Androger is file logger, that shows logged files in GUI interface. Has got support for watching multiple files, and filtering their content. It's suppose to be fast, simple & robust. Just run it and chose log file to be watched. This application requires Java 7 or greater to be installed (https://www.java.com/en/download/).

Big-Brother is a collection of J2EE filters and servlets that provide custom monitoring and auditing of web-applications, keeping track of who does what, when, and how often. It makes use of the jakarta-apache Struts framework for the interface GUI.

Yet another logger. Take a close look at it: It is very easy to use, very unified and extendable. You may attach your favourite set of loggers to this logger, and you still use only one API! This Java logger is used throughout the COMJAT.NET systems.

COMPAS J2EE is a non-intrusive performance instrumentation and monitoring toolkit for J2EE. It uses adaptive monitoring to automatically adjust the target coverage. COMPAS is completely portable across J2EE application servers and OSs.

Cross-language and cross-platform user's action tracking framework,enabling researchers to respect user's privacy through visual controls which allow users to start/stop/pause data recording,view logged data and opt out of a research study.

Comtor commons libs, includes: Logs, Exception handling, number printing, configuration files handling, TCP/UDP Server skel.

CorbaTrace is a helpful tool for tracing communications beetween Corba objects. Once CorbaTrace is installed, remote calls are intercepted and informations are stored in XML files. So, you will be able to apply filters and get XMI files to see the commu

Cricket Cage automatically creates JUnit TestCases for repeatable bugs and test scenarios. Include Cricket Cage's AspectJ code to install a code generator, then run the program to generate the TestCase. Finally, add the test case to your build.xml.

DevJournal is a tool for programmers that helps them be more purposeful and reflective about their work by tracking their edits and allowing them to save a collated, annotated history of their work session.

An eclipse plugin providing tail in view component.

Provides an API that allows your Java applications to generate and log internationalized messages along with creating localized exceptions. Also provides Java annotations and an ANT task to help automatically generate language resource bundles.

JCola is a file tailing application written in Java Swing. This multithreaded application can tail an unlimited amount of logfiles concurrently and simulates "tail -f" with much more functionality.

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.
