Automated State-Space Exploration for Configuration Management of Service-Oriented Applications
Bibliographic record
Abstract
Configuration management is a complex task, even for experienced system administrators, which makes self-managing systems a desirable solution. Self-management implies the need for a model based on which configuration changes may be decided. In previous work, we described a method for constructing a state-transition model of application behavior, by observing the application in simulation. This method relied on an expert to manage the (simulated) application in order to collect the necessary observations for constructing the model. However, that method was agnostic about (a) the size of the system space space as implied by the granularity of the observations, and (b) the sufficiency of the actual observations collected for understanding the application in a variety of configurations and environments. In this paper, we replace the (expensive) expert domain knowledge with automatic approaches to ensuring coverage of the application, and demonstrate the superiority of this approach. We present empirical data regarding state space and granularity to explore the use of state models for understanding applications.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
