Abstract
Tracing, a technique essential for unraveling the complexities of computer systems' behavior, involves the organized collection of low-level events, enabling anomaly identification, performance debugging, and root cause analysis. However, the significant overhead it imposes on large-scale systems, particularly in terms of performance and storage, has made it a less favorable tool for system maintenance. Previous efforts to mitigate tracing's burden have mostly centered around automating trace analysis but have primarily neglected the duration of events, a significant aspect of the information provided by tracers. To address these challenges, we propose an Adaptive Tracing method that leverages Language Models and kernel trace for precise system modeling. This novel approach minimizes overhead by recording detailed traces only during significant behavioral shifts and focusing on subsystems related to the root cause. Using a multi-task model, incorporating system call sequences and durations, we propose a root cause analysis method, enhancing model transparency and enabling targeted system tracing. Evaluation using a dataset of normal and noisy traces from an Apache server reveals that our Adaptive Tracer captures events related to abrupt changes with only 5.8% loss, reducing the collected trace by 77.1%, and accurately determining the respective noise set with 91.3% accuracy, outperforming previous state-of-the-art trace models by 20.9%.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
