Request-log-analyzer

This is a simple command line tool to analyze request log files of both Rails and Merb to produce a performance report. Its purpose is to find what actions are best candidates for optimization.

• Analyzes Rails log files (all versions), Merb logs, or any other log format
• Can combine multiple files (handy if you are using logrotate)
• Uses several metrics, including cumulative request time, average request time, process blockers, database and rendering time, HTTP methods and statuses, Rails action cache statistics, etc.) (Sample output: wiki.github.com/wvanbergen/request-log-analyzer/sample-output)
• Low memory footprint (server-safe)
• Fast
• MIT licensed

Request log analyzer was designed and built by Willem van Bergen and Bart ten Brinke.
