A Topology-Aware, Memory-Centric Architecture that Separates Root-Cause Derivation from Root-Cause Explanation

Researchers present OpsCortex, a multi-agent system that uses persistent operational memory and dependency graphs to automatically derive root causes of microservice failures, then leverages LLMs only for explanation rather than diagnosis. The architecture separates root-cause derivation from explanation, addressing a critical gap in autonomous operations by maintaining structured system knowledge that typical monitoring stacks discard.
