Sends your logs to files, sockets, inboxes, databases and various web services from PHP. It can log to files and syslogs, Send alerts and emails, Log specific servers and networked logging, Log to databases and lot more.
LogStashLogger extends Ruby's Logger class to log directly to Logstash. It supports writing to various outputs in logstash JSON format. This is an improvement over writing to a file or syslog since Logstash can receive the structured data directly. You can use a URI to configure your logstash logger instead of a hash. This is useful in environments such as Heroku where you may want to read configuration values from the environment. The URI scheme is type://host:port/path?key=value. Some sample URI configurations are given below.
A PHP logging package based on the idea of using closures for configurability and extensibility. It functions as a static class, but you can completely control the writing of log messages through a closure function (aka anonymous functions), or use the Analog\Logger wrapper that implements the PSR-3 specification. By default, this class will write to a file named sys_get_temp_dir() . '/analog.txt' using the format "machine - date - level - message\n", making it usable with no customization necessary.
Logrus is a structured logger for Go (golang), completely API compatible with the standard library logger. There is a support to add hooks for logging levels. For example to send errors to an exception tracking service on Error, Fatal and Panic, info to StatsD or log to multiple places simultaneously, e.g. syslog.
This library is still experimental and under early development. This is aimed to replace Nginx's standard ngx_http_log_module to push access logs to a remote server via an nonblocking socket. A common remote log server supporting sockets is syslog-ng.
This library is provided to allow standard python logging to output log data as json objects. With JSON we can make our logs more readable by machines and we can stop writing custom parsers for syslog type records. The fmt parser can also be overidden if you want to have required fields that differ from the default of just message.
log XI is a structured 12-factor app logger built for speed and happy development.A logger should be efficient and minimize performance tax. logxi encodes JSON 2X faster than logrus and log15 with primitive types. When diagnosing a problem in production, troubleshooting often means enabling small trace data in Debug and Info statements for some period of time.
tinylog is a lightweight open-source logging framework for Java and Android, optimized for ease of use. The logger of tinylog is static, so it isn't necessary to create an instance of the logger before logging. By default all log entries of the level info or higher are written to the console.
Lumberjack is a simple, powerful, and fast logging implementation in Ruby. It uses nearly the same API as the Logger class in the Ruby standard library and as ActiveSupport::BufferedLogger in Rails. This code aims to be extremely simple to use. The core interface it the Lumberjack::Logger which is used to log messages (which can be any object) with a specified Severity. Each logger has a level associated with it and messages are only written if their severity is greater than or equal to the level.
Logtron is a realtime logging library for NodeJS. Logger takes a set of meta information for the logger, that will be used by each backend to customize the log formatting and a set of backends that you want to be able to write to.Logger returns a logger object that has some method names in common with console.
Snort is an open source network intrusion prevention and detection system (IDS/IPS) developed by Sourcefire. Snort can perform protocol analysis and content searching/matching. It can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and much more.
TracerX is a .NET logger with a powerful viewer that supports filtering/coloring by threads, category, trace level, and more. Output can go to a circular log file, event log, console/command window, or Trace.WriteLine(). The viewer can collapse and expand method calls, view/walk
Netduino data logger for race motorcycle based on Netduino + programmed using C# and .NetMF. Logger to record GPS, 3 axis accelerometers, 2 axis gyro, TPS, EGT, Lambda, engine and air box temps, rpm, etc. PC data analysis code using C#
