  • Diagnostics for Anomalies in Cloud Services

    ICDE

    Cloud platforms involve multiple independently developed
    components, often executing on diverse hardware configurations
    and across multiple data centers. This complexity makes
    tracking various key performance indicators (KPIs) and manual
    diagnosing of anomalies in system behavior both difficult and
    expensive. In this paper, we describe PerfAugur, an automated
    system for mining service logs to identify anomalies and help
    formulate data-driven hypotheses. PerfAugur includes a…

    Cloud platforms involve multiple independently developed
    components, often executing on diverse hardware configurations
    and across multiple data centers. This complexity makes
    tracking various key performance indicators (KPIs) and manual
    diagnosing of anomalies in system behavior both difficult and
    expensive. In this paper, we describe PerfAugur, an automated
    system for mining service logs to identify anomalies and help
    formulate data-driven hypotheses. PerfAugur includes a suite of
    efficient mining algorithms for detecting significant anomalies
    in system behavior, along with potential explanations for such
    anomalies, without the need for an explicit supervision signal. We
    perform extensive experimental evaluation using both synthetic
    and real-life data sets, and present detailed case studies showing
    the impact of this technology on operations of the Windows Azure
    Service.
