Explore the intricacies of extracting analytics from complex OpenEmbedded builds in this informative conference talk by David Reyna of Wind River Systems. Delve into the powerful infrastructure behind Toaster, the GUI for OpenEmbedded, and learn how it leverages the bitbake event model to capture detailed build information. Discover techniques for managing and interpreting vast amounts of build data, including dependencies, causality, time, and space. Gain insights into overcoming challenges in event interpretation and handling hundreds of thousands of build events. Learn to develop command-line tools for analytics extraction and create custom event clients. Explore topics such as the event system features, available events, event clients, database integration, and custom event creation. Acquire practical knowledge on using events for debugging bitbake and implementing custom event UIs.
