Open Source Logging Software

Shorten your time of reading mega bytes of log files! DE 2016-01 Supporting Don HO's NotePad++ see http://notepad-plus-plus.org/ This sources are a dockable pattern search plugin for Notepad++ version 5.1 or later. With this plugin you can search for multiple patterns in any of the opened documents in NotePad++. You may want to tune your search using all fancy tricks from NPP like regular expressions or escaped patterns and give each of the searches different colors. The result will be stored in a dockable window in same ordering as in the origin and a double click allows you to jump to the original position. It is designed to treat log-files of typical size like 60MB. More features can be found in the help dialogue of the plugin. For generating the dll file I use a msdev compiler. If you like to port it to other OSs just let me know your changes and I'll incorporate it. Best Regards, Mattes H.

Visual Syslog Server for Windows is a free open source program to receive and view syslog messages. Useful when setting up routers and systems based on Unix/Linux. Visual Syslog Server for Windows has a live messages view: switches to a new received message. Helpful color highlighting. Useful message filtering. Customizable notification and actions.

Screen squid is web-based interface for viewing reports based on Squid proxy server log files. It can be accessed from web-browser through more than 50 reports. No extra files, only DB. All reports generated "on-the-fly". And we got personal cabinet for each user/group.

Monolog sends your logs to files, sockets, inboxes, databases and various web services. See the complete list of handlers below. Special handlers allow you to build advanced logging strategies. This library implements the PSR-3 interface that you can type-hint against in your own libraries to keep a maximum of interoperability. You can also use it in your applications to make sure you can always use another compatible logger at a later time. As of 1.11.0 Monolog public APIs will also accept PSR-3 log levels. Internally Monolog still uses its own level scheme since it predates PSR-3. Tidelift delivers commercial support and maintenance for the open source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use. Monolog 1.x support is somewhat limited at this point and only important fixes will be done. You should migrate to Monolog 2 where possible to benefit from all the features.

Fluent Bit is a super-fast, lightweight, and highly scalable logging and metrics processor and forwarder. It is the preferred choice for cloud and containerized environments. A robust, lightweight, and portable architecture for high throughput with low CPU and memory usage from any data source to any destination. Proven across distributed cloud and container environments. Highly available with I/O handlers to store data for disaster recovery. Granular management of data parsing and routing. Filtering and enrichment to optimize security and minimize cost. The lightweight, asynchronous design optimizes resource usage: CPU, memory, disk I/O, network. No more OOM errors! Integration with all your technology, cloud-native services, containers, streaming processors, and data backends. Fully event-driven design leverages the operating system API for performance and reliability. All operations to collect and deliver data are asynchronous.

swatchdog.pl started out as swatch, the "simple watchdog" for activity monitoring log files produced by UNIX's syslog facility. It has since been evolving into a utility that can monitor just about any type of log. The name has been changed to satisfy a request made by the old Swiss watch company.

[ set status to abandon - volunteers welcome ] The postfix-logwatch / amavis-logwatch log analyzers produce summaries, reports and statistics regarding the operation of postfix and amavis. Use standalone, or as a filter module for the open source logwatch utility.

SRG is a log file analyser and report generator for the Squid web proxy. It is fast and was created to allow easy integration with other authentication systems. SRG is flexible and can report right down the the level of individual files requested.

log2web is a software intended to expose on a simple web page the logs generated by log4j. The objective is to have an online log viewing tool to replace a "tail -f" plus some other benefits.

Logpp is a tool for preprocessing event logs and feeding relevant data to other programs for storing or in-depth analysis. Logpp reads lines appended to input files, matches the lines with patterns, and writes the results to given destinations.

Lire is a pluggable log analyzer, supporting HTTP, email, DNS, FTP, firewall and print services. Output generated can be txt, (X)HTML, PDF, RTF, and DocBook. The latter four support graphics. For news/support visit the project homepage.

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.

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.

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!

TailBlazer is a graphical version of the UNIX 'tail' utility. It allows you to monitor log files as they are written. New lines appear as they are written. TailBlazer takes this a step further by supporting pattern matching, filtering, and notification

A web-based human event (links/books read, songs played, etc.) logging tool focused on rich bibliographic support and library (as in books-on-shelves) systems integration.

AVirCAP is a system for manual and / or automated detection of CodeRed and Nimda type of hack attempts and virtually all other kinds of "logable" intrusion attempts. It can work stand alone or together with other additional AVirCAP machines in the LAN/W

AWStats Enterprise Manager is a tool for managing awstats configuration creation and logfile processing, in a multi-server environment. This script is designed to pull all the webserver logs, for every server, and parse them with awstats.

ASC is a tool to count traffic between users and different subnets. The most common usage is to measure individual users amount of traffic to and from the internet. Very easy to configure, see the documentation.

BCLF is the Binary Common Log Format, a fast, platform independent, streamable, compact logging format that resembles the Extended CLF logging format in content. The project goal is to make an Apache module and enhance the format without giving up speed.
