Orion+: Automated Problem Diagnosis in Computing Systems by Mining Metric Data

TL;DR

Orion+ enhances automated debugging by analyzing call stack data at a finer granularity, enabling efficient identification of impacted code segments and reducing developer debugging time.

Contribution

It introduces a call stack-based comparison approach with polynomial complexity for more precise bug localization in computing systems.

Findings

Effective bug localization at call stack level

Polynomial complexity ensures practical implementation

Reduces developer debugging effort

Abstract

This work presents the suspicious code at a finer granularity of call stack rather than code region, which was being returned by Orion. Call stack based comparison returns call stacks that are most impacted by the bug and save developer time to debug from scratch. This solution has polynomial complexity and hence can be implemented practically.
