  • Publication number: 20170322877
    Abstract: Embodiments provide techniques for estimating seasonal indices for multiple periods. Some embodiments can receive a signal comprising a plurality of measures sampled over a span of time from an environment in which one or more processes are being executed. Some embodiments may then extract a seasonal effector and a de-seasonalized component from the signal. Next, some embodiments can apply one or more spline functions to the seasonal effector to generate a first model. Some embodiments may then apply a linear regression technique to the de-seasonalized component to generate a second model. Some embodiments may then initiate actions associated with the code. Some embodiments may then generate a forecast of the signal based on the first model and the second model. Next, some embodiments may initiate, based at least in part on the forecast, one or more actions associated with the environment.

  • Publication number: 20170322861
    Abstract: Embodiments provide a thread classification method that represents stack traces in a compact form using classification signatures. Some embodiments can receive a stack trace that includes a sequence of stack frames. Some embodiments may generate, based on the sequence of stack frames, a trace signature that represents the set. Some embodiments may receive one or more subsequent stack traces. For each of the one or more subsequent stack traces, some embodiments may determine whether a subsequent trace signature has been generated to represent the sequence of stack frames included within the subsequent stack trace. If not, some embodiments may generate, based on the trace signature and other subsequent trace signatures that were generated based on the trace signature, the subsequent trace signature to represent the subsequent sequence of stack frames.

  • Patent number: 9692662
    Abstract: Data can be categorized into facts, information, hypothesis, and directives. Activities that generate certain categories of data based on other categories of data through the application of knowledge which can be categorized into classifications, assessments, resolutions, and enactments. Activities can be driven by a Classification-Assessment-Resolution-Enactment (CARE) control engine. The CARE control and these categorizations can be used to enhance a multitude of systems, for example diagnostic system, such as through historical record keeping, machine learning, and automation. Such a diagnostic system can include a system that forecasts computing system failures based on the application of knowledge to system vital signs such as thread or stack segment intensity and memory heap usage. These vital signs are facts that can be classified to produce information such as memory leaks, convoy effects, or other problems.

  • Publication number: 20160371181
    Abstract: The disclosed embodiments provide a system that detects anomalous events in a virtual machine. During operation, the system obtains time-series garbage-collection (GC) data collected during execution of a virtual machine in a computer system. Next, the system generates one or more seasonal features from the time-series GC data. The system then uses a sequential-analysis technique to analyze the time-series GC data and the one or more seasonal features for an anomaly in the GC activity of the virtual machine. Finally, the system stores an indication of a potential out-of-memory (OOM) event for the virtual machine based at least in part on identifying the anomaly in the GC activity of the virtual machine.

  • Patent number: 9256632
    Abstract: Techniques are provided for capturing events and activities that occur during a conference, generating metadata related to the events, and correlating the metadata with specific points in time, within the conference, at which the corresponding events occurred. The resulting temporally-correlated event metadata may be stored as part of the conference recording, or separate from the conference recording. Once the temporally-correlated event metadata has been stored for a conference, the conference may be indexed based on the metadata. The index may then be used to not only to locate a conference that satisfies specified search criteria, but to identify the points or snippets, within the conference, that correspond to the search criteria.

  • Publication number: 20150254330
    Abstract: Embodiments of the invention provide systems and methods for managing and processing large amounts of complex and high-velocity data by capturing and extracting high-value data from low value data using big data and related technologies. Illustrative database systems described herein may collect and process data while extracting or generating high-value data. The high-value data may be handled by databases providing functions such as multi-temporality, provenance, flashback, and registered queries. In some examples, computing models and system may be implemented to combine knowledge and process management aspects with the near real-time data processing frameworks in a data-driven situation aware computing system.

  • Patent number: 8965889
    Abstract: Systems, methods, and other embodiments associated with bi-temporal user profiling are described. An event is detected that occurs at a valid event time. In response to the event, a repository is accessed that stores data describing one or more user profiles that include a profile record valid time period specifying a time at which the given profile record is valid. A prior user profile record is retrieved that has a profile record valid time period that overlaps with the valid event time. An updated user profile record is created based, at least in part, on the event. The updated user profile record is saved with the valid event time demarcating the start of a profile valid time period. The prior user profile with the valid event time demarcating the end of the profile record valid time period is also saved for subsequent processing.

  • Patent number: 8478717
    Abstract: Embodiments of the invention provide systems and methods for a collaboration environment in which a number of different workspaces can use the same, reusable content. According to one embodiment, a method of providing collaboration using reusable content can comprise identifying a content item to be included in a first workspace of a plurality of workspaces of a collaboration environment. A first proxy representing the identified content item can be created. The first proxy can have a unique identifier within the first workspace. A mapping table record can be created for the first proxy that links the first proxy to the content item. Additionally, a cross-reference table record can be created for the first proxy. The cross-reference record can identify a relationship of the first proxy to another content item in the first workspace.
