Log filtering and interpretation for root cause analysis,”

by Hamzeh Zawawy , Kostas Kontogiannis , John Mylopoulos - in Software Maintenance, IEEE International Conference on, , 2010
"... Abstract-Problem diagnosis in large software systems is a challenging and complex task. The sheer complexity and size of the logged data make it often difficult for human operators and administrators to perform problem diagnosis and root cause analysis. A challenge in this area is to provide the ne ..."

Log Aggregator for Better Root-Cause-Analysis

by Gayatri Bisht
"... Abstract- Problem tracking in large software systems is a time consuming and difficult task. To do the Root-Cause-Analysis (RCA) of an issue occurred in a system, typically the concerned person has to go through different log files and event data. The complexity and size of the logs makes it often d ..."

Summary Getting Root Cause Analysis to Work for You

by Alexander (sandy Dunn
"... This paper provides several tips regarding how to make the most of Root Cause Analysis to progressively eliminate failures. Specific topics that are covered include: The need for training – why Root Cause Analysis is not just “common sense” The benefits of a team-based approach to Root Cause Analysi ..."

Enhancing Root Cause Analysis with Runtime Models and Interactive Visualizations

by Michael Szvetits, Uwe Zdun
"... Abstract. Recent research shows that runtime models can be used to build dynamic systems coping with changing requirements and execution environments. As software systems are getting bigger and more complex, locating malfunctioning software parts is no trivial task because of the vast amount of poss ..."

behaviour. In this paper we propose the usage of runtime models in combination with model-driven techniques and interactive visualizations to ease tracing between log file entries and corresponding software artefacts. The contribution of this paper is a repository-based approach to augment root cause

Contextual analysis of program logs for understanding system behaviors

by Qiang Fu, Jian-guang Lou, Qingwei Lin, Rui Ding, Dongmei Zhang, Tao Xie - In Proc. of 10th Working Conference on Mining Software Repositories (MSR’13 , 2013
"... Abstract—Understanding the behaviors of a software system is very important for performing daily system maintenance tasks. In practice, one way to gain knowledge about the runtime behavior of a system is to manually analyze system logs collected during the system executions. With the increasing scal ..."

learns essential contextual factors (e.g., the occurrences of specific program logs with specific parameter values) that cause a specific branch or path to be executed by the system. The mining and learning results can help system operators to understand a software system’s runtime execution logic

Mining Patterns and Rules for Software Specification Discovery ABSTRACT

by David Lo, Siau-cheng Khoo
"... Software specifications are often lacking, incomplete and outdated in the industry. Lack and incomplete specifications cause various software engineering problems. Studies have shown that program comprehension takes up to 45% of software development costs. One of the root causes of the high cost is ..."

DRACA: Decision Support for Root Cause Analysis and Change Impact Analysis for CMDBs

by Sarah Nadi, Ric Holt, Ian Davis, Serge Mankovskii
"... As business services become increasingly dependent on information technology (IT), it also becomes increasingly important to maximize the decision support for managing IT. Configuration Management Data Bases (CMDBs) store fundamental information about IT systems, such as the system’s hardware, softw ..."

, software and services. This information can help provide decision support for root cause analysis and change impact analysis. We have worked with our industrial research partner, CA, and with CA customers to identify challenges to the use of CMDBs to semi-automatically solve these problems. In this paper

Log-Based Reduction by Rewriting

by A. Elyasov, I. S. W. B. Prasetya, J. Hage, A. Elyasov, I. S. W. B. Prasetya, J. Hage , 2012
"... Abstract—Software systems often produce logs which contain information about the execution of the systems. When an error occurs, the log file with the error is reported for subsequent analysis. The longer the log file, the harder to identify the cause of the observed error. This problem can be consi ..."

Structured Comparative Analysis of Systems Logs to Diagnose Performance Problems

by Karthik Nagaraj, Charles Killian, Jennifer Neville , 2011
"... Diagnosis and correction of performance issues in modern, large-scale distributed systems can be a daunting task, since a single developer is unlikely to be familiar with the entire system and it is hard to characterize the behavior of a software system without completely understanding its internal ..."

These patterns are presented to the developer for inspection, to help them understand which system component(s) likely contain the root cause of the observed

Pitfalls in Aspect Mining

by Kim Mens, Andy Kellens, Jens Krinke
"... The research domain of aspect mining studies the problem of (semi-)automatically identifying potential aspects and crosscutting concerns in a software system, to improve the system’s comprehensibility or enable its migration to an aspect-oriented solution. Unfortunately, most proposed aspect mining ..."

techniques have not lived up to their expectations yet. In this paper we provide a list of problems that most aspect mining techniques suffer from and identify some of the root causes underlying these problems. Based upon this analysis, we conclude that many of the problems seem to be caused directly
