DrP: Meta’s Root Cause Analysis Platform at Scale

What this post added

Introduced DrP, a root cause analysis (RCA) platform designed to programmatically automate incident investigation. DrP features an expressive SDK for authoring investigation playbooks (analyzers) with ML algorithms for data access and problem isolation, a scalable backend for multi-tenant and isolated execution, seamless integration with mainstream workflows like alerts and incident management tools, and a post-processing system for automated mitigation actions. It has achieved widespread adoption at Meta, reducing MTTR by 20-80% and enhancing on-call productivity.
