A benchmark study evaluated AWS Nova Micro, a smaller and cheaper large language model, on log data analysis tasks including log parsing, error summarization, security event detection, anomaly detection, prediction, and summarization. The model performed well on parsing and summarizing logs, with accuracy comparable to ChatGPT-3.5 but at 14x lower cost per token. It showed high accuracy in detecting malicious content in logs and good performance on structured logs common in production environments (e.g., CDN, web access, AWS CloudTrail). However, it struggled with counting API calls accurately, anomaly detection, and predicting future log events. The study highlights the potential for LLMs to improve production logging systems cost-effectively, especially for structured log formats.
