Skylight functions as a sophisticated profiler tailored for Ruby and Rails applications, converting performance data into actionable insights that allow developers to spend less time troubleshooting and more time enhancing their applications. It classifies endpoints by a metric called "agony," which uniquely combines factors of slowness and usage frequency, helping you pinpoint the areas that will yield the highest returns on your optimization efforts. Through an examination of endpoint graphs, you can precisely identify where slowdowns occur, with the most pronounced bars in these graphs signifying the events that demand your immediate focus. Once you've implemented improvements in your code, redeploying your application is straightforward, with deployment events clearly marked on the overview graph for an easy visual comparison of your adjustments. You have the option to delve into a histogram of response times to uncover rare slowdowns that could skew your overall averages. Furthermore, the tool enables you to compile event sequences based on either time or memory usage, assisting in the detection of potential bottlenecks. This capability allows you to effectively identify your slowest responses, sharpening your attention on the differences between your quickest and slowest responses, which ultimately contributes to a more efficient application. By consistently tracking and optimizing your application, you can guarantee a more seamless user experience and improved performance in the long run, as well as continually adapt to changing user needs and application demands.
