Charity Majors has been on-call in one form or another since she was 17. She knows how to get to the bottom of system performance problems. After stints at Parse and Facebook, Charity and co-founder Christine Yen started Honeycomb, whose mission is to help software engineers use event data to explore and better understand their production systems. In this episode of Pivotal Insights, Charity joins Jeff and Dormain to talk about the challenges of debugging distributed systems, why a data-driven approach is the best way to get to the bottom of performance issues, and how software engineers can get their atrophied debugging muscles back into shape.
