Feedback form is now closed.
Diagnosing problems in distributed systems is time-consuming and heavily reliant on developer guesswork to know where to instrument the system. The Pythia “Just-in-Time” Instrumentation Framework uses statistical measures to detect where instrumentation is needed in a distributed system to isolate specific problems as they occur. We will demonstrate an initial proof of concept by showing that one key statistical measure - high-performance variation among work that is expected to perform similarly - can predict where additional instrumentation is needed.
