On Sequence-to-Sequence Models for Automated Log Parsing

arXiv:2602.07698v2 Announce Type: replace-cross Abstract: Context: Log parsing is a critical standard operating procedure in software systems, enabling monitoring, anomaly detection, and failure diagnosis. However, automated log parsing remains challenging due to heterogeneous log formats, distribution shifts between training and deployment data, and the brittleness of rule-based approaches. Objectives: This study aims to systematically evaluate how sequence modelling architecture, representation choice, sequence length, and training data availability influence automated log parsing performanc

Why this matters
Why now

The increasing complexity and distributed nature of software systems, coupled with advances in sequence-to-sequence models, make automated log parsing a critical area for improvement.

Why it’s important

Improved automated log parsing can significantly enhance software reliability, security, and operational efficiency, reducing downtime and maintenance costs for critical infrastructure.

What changes

The adoption of more robust and adaptive log parsing techniques, moving beyond brittle rule-based systems, will allow for better monitoring and anomaly detection in dynamic environments.
