Rails Analyzer

The Rails Analyzer project contains a collection of tools for Rails that let you discover biggest slow spots in your applications allowing you to best focus optimization efforts.

Tools

• The Production Log Analyzer examines Rails log files and gives a report showing you the worst speed offendors. It also includes action_grep which will give you all log results for a particular action.
• The Action Profiler lets you profile actions to determine points of optimization.
• Rails Analyzer Tools is a collection of tools for benchmarking and monitoring a Rails application. The most useful is rails_stat which gives a live counter of requests per second of a running Rails app.
• The SQL Dependency Grapher allows you to visualize the frequency of table dependencies in a Rails application.

Download

All tools can be downloaded from the Rails Analyzer project page.

Why?

Rails logs are a treasure trove of information just waiting to be mined, so I wrote these tools while working at The Robot Co-op to analyze and improve our websites.
