Google Jiffy-Web – Webpage Instrumentation & Measurement Suite
The first beta of Jiffy-Web was released on 23/6/2008. Good news to developers, Jiffy is an end-to-end real-world web page instrumentation and measurement suite.
What does it do? You can use Jiffy to:
- measure individual pieces of page rendering (script load, AJAX execution, page load, etc.) on every client
- report those measurements and other metadata to a web server
- aggregate web server logs into a database
- generate reports
How does it work?
- Measurement – using the jiffy.js script to measure activities on webpages
- Configuration – Apache proxy configuration
- Log – an ingestor that posts logs to a database
- Working DDLs for Oracle XE and higher
- Reporting – for Oracle, but MySQL is coming
- Reporting user interface – using the Yahoo! User Interface Library
According to Google Code, “you can use Jiffy end-to-end by
- including Jiffy.js in your pages and instrumenting them with the appropriate mark and measure calls
- Making the configuration changes needed to your proxy
- Adding the ingestor as a cron job on your web servers, with appropriate connection strings
- Setting up the data model
- Editing the reporting configuration and deploying the reporting tools
