Open Source ChromeOS Logging Software

This small tool allows the user to graphically examine ddrescue's mapfiles in a user friendly GUI application. The Main window displays a block grid with each block's color representing the block types it contains. Many people know this type of view from defragmentation programs. The program is written in Object Pascal using the Lazarus IDE. It can be compiled to run on Windows, GNU/Linux and probably OS X, too. The downloads include binaries for the respective target platform and the project files (source code). Update 2022/02/25: ddrescueview version 0.4.5 has been released. This maintenance release restores compatibility with ddrescue 1.24 and later. Please consider testing this version. Report issues in the bug tracker if you have a sourceforge account, or by email to <mbit-kiel@users.sourceforge.net>

NSClient++ is a windows service that allows performance metrics to be gathered by Nagios (and possibly other monitoring tools). It is an attempt to create a NSClient and NRPE compatible but yet extendable performance service for windows.

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.

swift-log is the official, vendor-neutral logging API for Swift, providing a small, performant core that libraries and applications adopt to avoid logger lock-in. It defines common logging semantics and levels, plus a lightweight façade that backends can implement—so the same application code can run with different logging engines (e.g., OSLog on Apple platforms or custom sinks on servers). The package embraces Swift Package Manager, offers a clean Logger API, and is widely used across the Swift on server and Apple-platform ecosystems. The repo’s release notes and ecosystem links show active maintenance, CI coverage for recent Swift versions, and community-supplied backends. By decoupling the API from any one implementation, swift-log simplifies composition: frameworks can log consistently without dictating the logging stack to end users. It’s a foundational building block for production Swift services, tools, and apps looking for consistent, structured telemetry.

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.

BASE is the Basic Analysis and Security Engine. It is based on the code from the Analysis Console for Intrusion Databases (ACID) project. This application provides a web front-end to query and analyze the alerts coming from a SNORT IDS system.

360-FAAR (Firewall Analysis Audit and Repair) is an offline, command line, firewall policy manipulation tool to filter, compare to logs, merge, translate and output firewall commands for new policies, in Checkpoint dbedit, Cisco ASA or ScreenOS commands, and its one file! Read Policy and Logs for: Checkpoint FW1 (in odumper.csv / logexport format), Netscreen ScreenOS (in get config / syslog format), Cisco ASA (show run / syslog format), 360-FAAR compares firewall policies and uses CIDR and text filters to split rulebases / policies into target sections and identify connectivity for further analysis. 360-FAAR supports, policy to log association, object translation, rulebase reordering and simplification, rule moves and duplicate matching automatically. Allowing you to move rules to where you need them. Build new rulebases from scratch with a single 'any' rule and log files, with the 'res' and 'name' options. Switch into DROPS mode to analyse drop log entries.

Recursive computing and matching of Context Triggered Piecewise Hashing (aka Fuzzy Hashing). Supports Windows, *nix, BSD, OS X, etc.
