Debugging and Observability for Distributed Ray Applications - SangBin Cho, Anyscale

Developing distributed applications is difficult, and Ray tries to make it easier. However, it’s a well-known fact that most of our time is spent debugging, not actually writing the initial code. This talk will describe the vision for making debugging applications during development and monitoring them in production simple when using Ray. First, we’ll describe the recent improvements that we’ve made to metrics monitoring and the Ray dashboard. Then, we’ll present a few possible future directions including dashboard improvements, structured events, and distributed tracing. This will include a short demo of how to debug an application using these tools.
