Log Anomaly Detection with Large Language Models via Knowledge-Enriched Fusion

Explore how cutting-edge AI research in log anomaly detection can transform your enterprise's operational intelligence, enhance security, and drive efficiency.

Executive Impact Summary

This research introduces EnrichLog, a novel training-free framework for log anomaly detection that significantly enhances accuracy and interpretability by integrating corpus-specific and sample-specific knowledge. Its two-step inference process ensures efficiency, making it highly suitable for enterprise deployments where real-time, precise anomaly detection is critical for maintaining system reliability and security.

EnrichLog leverages raw log text for anomaly detection, fusing corpus-specific knowledge (summarized documentation) and sample-specific knowledge (historical examples and explanations). This avoids the limitations of template-based methods that often lose semantic information or struggle with ambiguous log patterns. The two-step inference strategy balances efficiency and accuracy by initially filtering confidently normal logs with a lightweight prompt before applying RAG for anomalous entries.

The results demonstrate that EnrichLog consistently improves anomaly detection performance across all evaluated datasets. The incorporation of both corpus- and sample-specific knowledge significantly enhances model confidence and detection accuracy, especially for misclassified instances. It effectively handles ambiguous log entries where a single template might correspond to both normal and anomalous events, achieving 92% F1-score on ambiguous BGL subset. The two-step approach also significantly reduces inference latency without sacrificing detection performance.

Real-world Ambiguity Resolution

In production systems, certain log templates like "machine check enable" (as shown in Figure 1 of the paper) can correspond to both normal and anomalous events. Traditional template-based anomaly detection systems often fail to differentiate these cases, leading to false positives or missed anomalies. EnrichLog, with its sample-specific enrichment and leveraging raw log context, was able to achieve a 92% F1-score on a subset of the BGL dataset containing such ambiguities. This highlights its ability to reason over contextual cues beyond simple template matching, making it robust for complex real-world scenarios.
