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.

DirJack is a java written tool to monitor directories in your filesystem. The main feature is to react on changes within a directory i.e. you can define the behaviour what to do when files are added, edited or removed.

Distributed event bus library for passing application events to listeners running anywhere on the network. Library is a lightweight wrapper over the JGroups toolkit with event filtering features.

dmclTLA will take a dmcl trace file (level=10) and summarize key information like average duration per call type, and commands that took the longest to execute. Html and plain-text files are created.

This project provides a couple of Log4j appenders to log into Domino databases from various contexts like servlets, Java clients and, of course Domino Java agents.

This plugin aims to provide an intuitive way of filtering and sorting logs that are coming from ssh or serial connection. Operating systems: Windows/Linux

An eclipse plugin providing tail in view component.

EventReaper is a flexible message consumption and distribution platform that is primarily designed to monitor events/messages.

Feed State is used to view (and store) log files of different formats from many different processes over a network. A massive variety of logs are supported: XML, database, all ASCII log files, all parsed into a common format for viewing and analysis.

Lightweight graphical Java based file watcher similar in functionality to tail. Includes additional per-file features like pausing, setting polling frequency, font size, and buffer size, refresh, in-pause tail, and clear.

Flogger is a structured logging API for Java that decouples how you log from where logs ultimately go, making it easy to change backends without rewriting application code. Instead of building messages eagerly, it uses lazy parameter evaluation so expensive string building only happens when a log statement is actually emitted. The API encourages structured key–value context and fine-grained rate limiting, which helps keep logs informative without flooding systems during high-traffic or error storms. Handlers (backends) can route the same log record to multiple destinations—console, files, cloud logging—while preserving structured fields for search and alerting. Its fluent style reduces boilerplate and guides developers toward consistent log levels, formatting, and metadata. Because it’s designed for large codebases, Flogger emphasizes performance, binary size discipline, and compatibility with existing logging infrastructures.

FlowBuffer is a flow/netflow buffer and splitter: configure your switch to push flow data into FlowBuffer, and FlowBuffer forwards it to unlimited destinations. Offloads processing from the switch to another machine. Centralized management. Runs on Windows.

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

GILoT is an interpreting and formatting log tail:er. As each log entry is matched and formatted against customizeable rules, only relevant data is parsed. GILoT features, atm, two separate user interfaces, a console UI and an ncurses/charva TUI.

The Genalyze log analyzer, a simple yet highly extensible framework for parsing log files, was designed for parsing T-Server log files generated by Genesys contact center software platform, yet is generic and easy enough to adapt for other log formats.

GeneSyS is an open generic framework for network and system management, based on intelligent software agents using web-services/SOAP. It is a supervision tool for monitoring, management and control of distributed applications built with Java, .NET, PHP.

Search words in text files, display matching lines in tabs. Options to save results, exclude words, display the line numbers. Tiny file for searching big text files. Please leave feedback to help improve the application. Documentation coming soon.

The High Interaction Honeypot Analysis Toolkit (HIHAT) allows to transform arbitrary PHP applications into a web-based Honeypot. A semi-automatic user interface supports the analysis process, scans for attacks etc.

Hyperic is application monitoring and performance management for virtual, physical, and cloud infrastructures. Auto-discover resources of 75+ technologies, including vSphere, and collect availability, performance, utilization, and throughput metrics.

HypoLog is a collection of simple logging libraries for different platforms with an emphasize on ease of use. Currently supported are Java and .NET.

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.

A client/server application designed to let the user monitor a directory tree on a remote machine by creating snapshots of current file status in order to later detect file modification, addition and/or removal.

It's a cross platform utility designed for performing various checksumming activities. It supports verity of standards including ADLER-32, CRC-32, MD2, MD5, MURMUR-32, MURMUR-128, SHA-1, SHA-256, SHA-384, SHA-512 and SIPHASH24. Also generated results can be validated within the application. Results can be saved to a text file format. It can batch process folders as well. This tool requires Java Run-time Environment 7 or higher to use.

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.
