Abstract: A method and system are provided. The method includes performing, by a logs-to-time-series converter, a logs-to-time-series conversion by transforming a plurality of heterogeneous logs into a set of time series. Each of the heterogeneous logs includes a time stamp and text portion with one or more fields. The method further includes performing, by a time-series-to-sequential-pattern converter, a time-series-to-sequential-pattern conversion by mining invariant relationships between the set of time series, and discovering sequential message patterns and association rules in the plurality of heterogeneous logs using the invariant relationships. The method also includes executing, by a processor, a set of log management applications, based on the sequential message patterns and the association rules.

Abstract: Disclosed are a testing framework—SETSUD Ō—that uses perturbation-based exploration for robustness testing of modern scalable distributed systems. In sharp contrast to existing testing techniques and tools that are limited in that they are typically based on black-box approaches or they focus mostly on failure recovery testing, SETSUD Ō is a flexible framework to exercise various perturbations to create stressful scenarios. SETSUD Ō is built on an underlying instrumentation infrastructure that provides abstractions of internal states of the system as labeled entities. Both novice and advanced testers can use these labeled entities to specify scenarios of interest at the high level, in the form of a declarative style test policy. SETSUD Ō automatically generates perturbation sequences and applies them to system-level implementations, without burdening the tester with low-level details.
