In the realm of Artificial Intelligence for IT operations (AIOps), the integration of AI with the vast amount of data generated by IT processes, particularly in cloud infrastructures, is aimed at providing actionable insights to enhance operational efficiency and maximize availability. A wide array of challenges and opportunities exist within this field, with a focus on leveraging AI capabilities to address various problems. This review delves into the vision of AIOps, highlighting trends, challenges, and opportunities while specifically examining the underlying AI techniques. One key challenge discussed is the handling of noisy data in log analysis. Annotating log data poses difficulties even for domain experts, leading to issues such as extreme class imbalance and errors compounding through processing steps. Additionally, realistic public benchmark datasets for anomaly detection are limited in their ability to showcase real-world incidents accurately, often relying on simplistic rules for success. Furthermore, the need for improved log language models is emphasized, with advancements in neural NLP models showing promise but still requiring enhancements for encoding semi-structured logs effectively. Incorporating domain knowledge into AI models is also crucial for enhancing anomaly detection systems by providing context and understanding complex incidents. The review also touches upon the challenges posed by large volumes of log data in industrial settings, emphasizing the need for specialized handling due to the heavy nature of log content compared to telemetry data. Overall, this detailed exploration sheds light on key areas within AIOps where advancements in AI techniques can drive significant improvements in operational efficiency and effectiveness.
