Method tracer for Statsd written in Ruby

Tracee is a simple extensible logger with stack tracing, benchmarking, preprocessing, and severity-based output splitting. Tracee is meant for development and debugging of any type of application or library, and compatible with Rails. The main reason of its existence is to help you see through a stack.

Trace Ruby files.

Generate a visua graph of method calls

TraceHedaer is to inspect how the response headers would be changed by Rack middleware, and display them in your terminal.

Complete APM solution with distributed tracing, metrics, code monitoring, and security scanning for Ruby and Rails applications

"tracelogger host" sends the results of `traceroute #{host}` to syslog.

A Ruby interface to the Traceparts API

Log data preprocessor

A simple way to see time expiration in your Rails log files

Log errors and objects changes to Tracer.

Simple and fast tracer for your Ruby code. It's like puts debugging but on steroids.

Print TracePoint(:b_call, :b_return, :c_call, :c_return, :call, :return, :class, :end, :thread_begin, :thread_end) in tree view, to console or html

Traceur Compiler supported Javascript with Sprockets

The TraceView gem provides performance instrumentation for MRI Ruby, JRuby and related frameworks.

Intelligent visualization of software traces

Wrap the methods of a class or module to output call info. See a tree of calls made to wrapped methods with argument values and return values.

Enable tracing by setting the TRACE environment variable to a list of the names of trace classes you want to investigate. The enabled tracing is generated in a nested format, with significant support for exceptions and debugging.
