Anomaly Detection and Root Cause Analysis for Microservice Systems

arXiv:2606.09942v1 Announce Type: cross Abstract: Microservice systems are widely used to build cloud applications, yet their complexity makes failures inevitable, degrading user experience and causing economic loss. Automated anomaly detection and root cause analysis (RCA) are now active research areas, but existing techniques share five limitations. First, most treat anomaly detection and RCA separately, assuming anomalies are detected correctly, and falter when detection is imprecise due to noise or delay. Second, they focus on metrics, logs, and traces, leaving event data such as API calls

Why this matters
Why now

The increasing complexity and widespread adoption of microservice architectures in cloud applications necessitate more sophisticated anomaly detection and root cause analysis due to inevitable failures.

Why it’s important

This research addresses a critical limitation in current AI/ML operations by integrating anomaly detection and root cause analysis, which is vital for maintaining the reliability and performance of cloud infrastructure.

What changes

This research proposes a more robust approach to system reliability by overcoming the limitations of current anomaly detection and RCA techniques, especially concerning precision and diverse data types beyond metrics.
