User generated data is an old problem. Systems and network telemetry, page analytics and application state combine to form an ever growing mountain of data collected by today's tools. Collecting and storing this data requires more than just a single application, having no single point where the user touches the system and gets an answer makes debugging a nightmare and reproducing the error intractable. Distributed systems require a clear perspective on production systems and access to data in real time to have any hope of solving complex problems related to state, all while not impacting user experience.
We will explain the problem, the pains and how we solved them. Develop in production; push code to development.
Clipping is a handy way to collect important slides you want to go back to later.
