Title: Survey on Models and Techniques for Root-Cause Analysis,
Abstract: Automation and computer intelligence to support complex human decisions
becomes essential to manage large and distributed systems in the Cloud and IoT
era. Understanding the root cause of an observed symptom in a complex system
has been a major problem for decades. As industry dives into the IoT world and
the amount of data generated per year grows at an amazing speed, an important
question is how to find appropriate mechanisms to determine root causes that
can handle huge amounts of data or may provide valuable feedback in real-time.
While many survey papers aim at summarizing the landscape of techniques for
modelling system behavior and infering the root cause of a problem based in the
resulting models, none of those focuses on analyzing how the different
techniques in the literature fit growing requirements in terms of performance
and scalability. In this survey, we provide a review of root-cause analysis,
focusing on these particular aspects. We also provide guidance to choose the
best root-cause analysis strategy depending on the requirements of a particular
system and application.
