MiniProfiler/rack-mini-profiler
Rack Mini Profiler
This project is a performance analysis tool for Ruby applications using the Rack interface. It monitors request execution times and resource usage, serving as a profiler for web applications to measure latency and identify bottlenecks.
The tool provides specific analyzers for database query performance, memory allocations, and garbage collection statistics. It generates call stack flamegraphs to visualize time distribution across methods and renders speed badges and timing metrics directly onto HTML pages.
The system covers broader performance profiling capabilities including custom code block tracking, profiling data export to remote URLs, and production performance sampling. It includes mechanisms for profiling data persistence across different storage backends and implements access control to restrict who can view sensitive performance metrics.
Features
- Application Performance Profiling - Analyzes web application performance by measuring request execution times and identifying bottlenecks.
- Ruby Monitoring Tools - Provides a comprehensive suite of monitoring tools specifically designed for Ruby applications using the Rack interface.
- Flamegraph Generators - Generates flamegraph visualizations from profiling data to identify the most time-consuming methods in a request.
- Memory Leak Detectors - Tracks memory allocations and garbage collection statistics to identify memory leaks in Ruby applications.
- Memory Allocation Tracking - Monitors per-request memory allocations and garbage collection statistics to detect leaks and optimize resource usage.
- Database Instrumentation - Instruments database drivers to capture timing and statistics for every query executed during a request.
- Call Stack Visualizers - Generates hierarchical flamegraphs to visualize the application call stack and identify execution bottlenecks.
- Request Memory Profilers - Provides detailed tracking of per-request memory allocations and garbage collection statistics to identify leaks.
- Request Performance Metrics - Renders speed badges and detailed timing metrics directly onto HTML pages for every request.
- Rack Application Profilers - Provides a performance analysis tool specifically for Ruby applications using the Rack interface.
- Request Middleware - Uses Rack middleware to intercept requests and measure resource usage and execution time across the request cycle.
- Web Request Profilers - Profiles the execution path and timing of individual HTTP requests to pinpoint bottlenecks in the code.
- Database Query Optimizations - Tracks query duration and frequency to help identify and optimize inefficient database calls.
- Query Performance Monitors - Analyzes execution statistics for database queries across various drivers and ORMs to identify slow operations.
- Request Profiling Sampling - Reduces performance overhead by activating full profiling only for a random subset of incoming requests.
- Database Query Monitors - Tracks execution time and performance statistics for database queries across different ORMs and drivers.
- Production Program Sampling - Records performance metrics from a random sample of live production requests to diagnose intermittent slowdowns.
- Code Block Timing - Allows tracking the elapsed time and resource consumption of specific, user-defined code blocks.
- Response Body Injection - Renders performance metrics and speed badges as a visual overlay directly within the HTML response body.
- المراقبة والملاحظة - Performance profiler for Ruby rack applications.
- Profiling and Benchmarking - Profiler for development and production Rack apps.
- Ruby Frameworks and Tools - Performance profiling middleware for Rack.
