Abstract

fetched live from OpenAlex

Modern IT environments collect and analyze increasingly large volumes of data for a growing number of purposes (e.g., automated management, security, regulatory compliance, etc.). Simultaneously, such environments are challenged by the need to minimize their environmental footprints. A general solution to this problem is to utilize IT resources more efficiently. This paper describes our work to systematically evaluate the inefficiencies in the information collection and analysis of several widely-used IT applications, to implement a more efficient solution, and to quantify the improvements. In particular, the logging of HTTP transactions by the Apache Web server and of network events by the Bro intrusion detection system are converted from text files to DataSeries. The costs of recording, storing and analyzing the information in the different formats are thoroughly evaluated and compared. We converted the text logs to DataSeries online, with no discernable overhead on the logging applications. We achieved upto a 7x decrease in the logfile sizes relative to the sizes of the default text logs, and speedups of 3x-8.4x to analyze the logfiles.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
