Extract internal monitoring data from application logs for collection in a time-series database. mtail is a tool for extracting metrics from application logs to be exported into a timeseries database or timeseries calculator for alerting and dashboarding. It fills a monitoring niche by being the glue between applications that do not export their own internal state (other than via logs) and existing monitoring systems, such that system operators do not need to patch those applications to instrument them or writing custom extraction code for every such application. The extraction is controlled by mtail programs which define patterns and actions. Metrics are exported for scraping by a collector as JSON or Prometheus format over HTTP, or can be periodically sent to a collectd, StatsD, or Graphite collector socket. Precompiled binaries for released versions are available in the Releases page on Github. Using the latest production release binary is the recommended way of installing mtail.

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.

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.

Java logging can be a Kafkaesque mess of complexity that buys you little. Getting even the simplest logging working can be comically hard, and it often gets worse at scale as your needs become more sophisticated. Timbre offers an all Clojure/Script alternative that's fast, deeply flexible, easy to configure with pure Clojure data, and that just works out the box. No XML. Easily filter logging calls by any combination of: level, namespace, and appended. Zero overhead compile-time level/ns elision. Useful built-in appenders for out-the-box Clj+Cljs logging. Powerful, easy-to-configure rate limits and async logging. Logs as Clojure values (v3+). Small, simple, cross-platform codebase. 3rd-party tools, appenders, etc. No XML or properties files. A single, simple config map, and you're set. Simple, flexible fn appender model with middleware. Great performance at any scale.

spdlog is a header only library. Just copy the files under include to your build tree and use a C++11 compiler. It provides a python like formatting API using the bundled fmt lib. spdlog takes the "include what you need" approach, your code should include the features that actually needed. For example, if you only need rotating logger, you need to include "spdlog/sinks/rotating_file_sink.h". spdlog provides various log targets, which are, rotating log files, daily log files, console logging (colors supported), syslog, Windows event log, and Windows debugger (OutputDebugString(..)). Easily extendable with custom log targets. Log filtering, log levels can be modified in runtime as well as in compile time. Support for loading log levels from argv or from environment var. Backtrace support, store debug messages in a ring buffer and display later on demand.

Cinemagoer is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.

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.

Single header C++ logging library. It is extremely powerful, extendable, light-weight, fast performing, thread and type-safe, and consists of many built-in features. It provides the ability to write logs in your own customized format. It also provides support for logging your classes, third-party libraries, STL and third-party containers, etc. Easylogging++ is a single header efficient logging library for C++ applications. It is extremely powerful, highly extendable, and configurable to users' requirements. It provides the ability to write your own sinks (via featured referred as LogDispatchCallback). This library is currently used by hundreds of open-source projects on GitHub and other open-source source control management sites. If you are working on a small utility or large project in C++, this library can be handy. Its based on single header and only requires to link to single source file.
