Request-log-analyzer <img src=“https://secure.travis-ci.org/wvanbergen/request-log-analyzer.png” />¶ ↑
This is a simple command line tool to analyze request log files in various formats to produce a performance report. Its purpose is to find what actions are best candidates for optimization.
-
Analyzes log files. Currently supports: Amazon S3, Apache, Delayed::Job, Merb, Mysql, PostgreSQL, Rack, Rails and more.
-
Combines multiple files and decompresses compressed files, which comes in handy if you are using logrotate.
-
Uses several metrics, including cumulative request time, mean request time, process blockers, database and rendering time, HTTP methods and statuses, Rails action cache statistics, etc.) (Sample output: github.com/wvanbergen/request-log-analyzer/wiki/sample-output)
-
Runs on any MRI 1.9+ compatible Ruby, has a low memory footprint and is reasonably fast, so it is safe to run on a production server.
See the project wiki at github.com/wvanbergen/request-log-analyzer/wiki for documentation and additional information.
Install request-log-analyzer as a Ruby gem (you might need to run this command as root by prepending sudo
to it):
$ gem install request-log-analyzer
To analyze a Rails log file and produce a performance report, run request-log-analyzer like this:
$ request-log-analyzer log/production.log
For more details, other file formats, and available command line options, see the project’s wiki at github.com/wvanbergen/request-log-analyzer/wiki
Request-log-analyzer was designed and built by Willem van Bergen and Bart ten Brinke.
