Abstract

fetched live from OpenAlex

Numerous algorithms have been proposed over the years to predict performance metrics and detect performance anomalies in microservices based applications. However, most models specialize in either performance prediction or anomaly detection. As a result, multiple models are often required to monitor cloud-native applications effectively. Given the distributed nature of modern cloud-native systems, performance and health monitoring is carried out through various channels, and using separate models for each task adds complexity to the monitoring process. Therefore, this paper aims to investigate the use of multimodal data to integrate performance prediction and anomaly detection methods. For this purpose, we utilize simple Graph Neural Networks to predict latency distribution, as opposed to a single latency value for traces generated by a microservices system. The predicted latency distribution is then fed to several Machine Learning models to predict trace based anomalies. Our results show that all models tested can achieve accuracy of more than 96% and with good precision and recall values in a heavily unbalanced Train Ticket dataset.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
