GALA: Graph-Augmented LLM Agents for Root Cause Analysis and Incident Response in Microservices

Yifang Tian, Yaming Liu, Zichun Chong +3

Microservice root cause analysis (RCA) requires correlating failures across heterogeneous telemetry within complex service dependency graphs. Existing methods often rely on a singl…

FAME: Failure-Aware Mixture-of-Experts for Message-Level Log Anomaly Detection

Huanchi Wang, Zihang Huang, Yifang Tian +3

Production systems generate millions of log lines daily, yet most anomaly detectors operate at the session or window-level, flagging groups of lines rather than identifying the spe…

GALA: Can Graph-Augmented Large Language Model Agentic Workflows Elevate Root Cause Analysis?

Yifang Tian, Yaming Liu, Zichun Chong +2

Root cause analysis (RCA) in microservice systems is challenging, requiring on-call engineers to rapidly diagnose failures across heterogeneous telemetry such as metrics, logs, and…
