Open Source Linux Logging Software - Page 11

EasyLogHandler is a Symfony-compatible logging handler built on top of Monolog. It formats logs in a cleaner and more readable style, especially during development, enhancing the developer experience. By simplifying log output and highlighting important information it makes debugging and application monitoring more intuitive.

Echelog is a distributed system consisting of agents and one or more servers. Agents, distributed on computers over network, are monitoring the state of hosts and network. Collected data are sent to servers where they are processed and stored.

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.

Epilog is a multi-file logging program written in C using GTK+ capable of doing log coloring according to key words and doing reports.

Esyslogd is an alternative to syslogd. Esyslogd is threaded and it provide an API to get log entries, allready parsed, by TCP/IP.

EventWatcher is a KDE application which lives in the kde system tray and notifies users about various "events" which are collected via plugins.

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

Managing large application state easily, resiliently, and with high performance is one of the hardest problems in the cloud today. The FASTER project offers two artifacts to help tackle this problem. FASTER Log is a high-performance concurrent persistent recoverable log, iterator, and random reader library in C#. It supports very frequent commit operations at low latency, and can quickly saturate disk bandwidth. It supports both sync and async interfaces, handles disk errors, and supports checksums. FASTER KV is a concurrent key-value store + cache (available in C# and C++) that is designed for point lookups and heavy updates. FASTER supports data larger than memory, by leveraging fast external storage (local or cloud). It also supports consistent recovery using a new checkpointing technique that lets applications trade-off performance for commit latency.

FEDLibrary a portable c++ library for common use. Please refers to git repository.

FW1-Loggrabber is a command-line tool to grab logfiles from Checkpoint FW-1 remotely using Checkpoints LEA (Log Export Api), which is one part of Checkpoints OPSEC API.

FWReport is a log parser and reporting tool for IPTables. It generates daily and monthy summaries of the log files, allowing the admin to free up substantial time, maintain better control over security of the network, and reduce unnoticed attacks.

Fail2Ban monitors log files like /var/log/pwdfail or /var/log/apache/error_log and bans failure-prone addresses. It updates firewall rules to reject the IP address or executes user defined commands. Please see code and download from https://github.com/fail2ban/fail2ban . SF Fail2ban portal might not be up-to-date

!! THIS PROJECT HAS MOVED TO GITHUB !! !! https://github.com/durzo/fail2sql !! Fail2SQL is an addon to Fail2Ban which logs information to a MySQL database. This information can then be used in reports, graphs or by third party programs to take further action such as permanent blocking, reporting to ISP etc.

Squidace is a simple and very fast report generating tool per user/ip/name from SQUID log file. The reports will be sent via email.

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.

The graphical `tail -f`. This is a graphical tool to watch text file as they grow, dynamically.

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.

FGT, the Flexible Graphing Tool is a cgi for producing statistics based on any data-set. It is intended to be used for summarised data, taking up far less space than the original logs.

FlexMon is a flexible system monitoring system for Unix. In a client-server framework, plugins for e.g. load average, process status, disk status, CPU fan/temerature are provided. A command-line client exists, with a GUI and CGI interface to come.

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.

Flogger - a Free Logger. An easy to use and easy to customize logging library that works on a wide range of operating systems. Write your log entries effortlessly and efficiently to the console, to a file, to a data base or to some other source.

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

Free Agents DIDS is a distributed intrusion detection system that you place on each host on your network. Agents intercommunicate with aes encryption, automatically alert you, and secure your network for free!

Frontier Data System is a collection programs for data acquisition and data mining. It uses MySQL and PHP to monitor process variables and performance of shop floor equipment. Produces information on issues such as cycle time, downtime and SPC.
