Last year, the Skylight team gave a talk called Inside Rails: The Lifecycle of a Request. In that talk, we covered everything that happens between typing a URL into your browser to a request reaching your Rails controller action. But that talk ended with a cliffhanger: Once we are in the controller action, how does Rails send our response back to the browser?

While Skylight was originally developed to instrument web requests, we understand the web interface is only one part of your server-side application. For this reason, we've been hard at work preparing Skylight for Background Jobs!

Most Rails developers should be pretty familiar with this work flow: open up a controller file in your editor, write some Ruby code inside an action method, visit that URL from the browser and the code you just wrote comes alive. But have you thought about how any of this works? How did typing a URL into your browser's address bar turn into a method call on your controllers? Who actually calls your methods?

Code Triage is an open source app built to help other open source projects. Popular open source projects receive a lot of bug reports, feature requests, and pull requests every day, and just reading through all of them can be a huge time sink for their maintainers. Here at Skylight, we are involved in a number of popular open source projects ourselves, so we understand this problem pretty well!

Every single app — large or small, open source or not — has room for improvement when it comes to performance. This is why we created Skylight for Open Source to give open source contributors the tools they need to find these issues. Over the next week, we'll show you three different open source apps running on Skylight, each with their own unique performance challenges, varying in complexity.

Today, we released version 2.0 of the Skylight Agent. 2.0 doesn't introduce any new APIs, but we did rewrite the SQL Lexer to support more varieties of queries. We also spent a lot of time on internal refactoring and improved our error logging. Since we follow semantic versioning, we also took the opportunity to drop support for some older dependencies and environments. Read on for more information about upgrading as well as some technical details on our internal changes.

Using Skylight to Solve Real-World Performance Problems by Yehuda Katz, Godfrey Chan & Krystan Huffmenne

Skylight is a smart profiler for Ruby and Rails applications. It turns performance data into actionable insights, so you spend less time diagnosing and more time improving.

Skylight makes it easy to understand and act on your app’s performance data:

  • Rails Performance Reporting: Skylight visualizes all your app’s performance data in a way that makes it easy to understand and act on.
  • Sources Of Agony: Skylight sorts your endpoints by “agony” — a combination of popularity and response time — to show you which endpoints to improve for the biggest performance gains.
  • Endpoint Intelligence: Interact with Skylight’s endpoint data to understand the events that lead to slowdowns and how to prevent them in the future.
  • Communicate Improvements: Our weekly trends email distills your performance data into a beautiful, actionable report that helps you catch slowdowns before your customers do.

Try it yourself! Make friends with performance data, no credit card required.
