摘要： An unsupervised pattern extraction system and method for extracting incident and root cause patterns from various kinds of machine data such as system-level metric values, system call traces, and semi-structured or free form text log data and performing holistic root cause analysis for distributed systems. The system utilizing Natural Language Processing and machine learning techniques to extract incident and root cause information from received incident reports and other system data. The system consists of both real time data collection (104) and analytics functions (200). The previously reported incident data is used to discover and apply remediation techniques to utilize prior remediation efforts to automatically classify and correct incidents. The system may then annotate a remediation data file with the technique applied. The system will utilize prior known remediation techniques for identified categories to predict and prevent future issues.

摘要： An unsupervised pattern extraction system and method for extracting user interested patterns from various kinds of data such as system-level metric values, system call traces, and semi-structured or free form text log data and performing holistic root cause analysis for distributed systems. The distributed system includes a plurality of computer machines or smart devices. The system consists of both real time data collection and analytics functions. The analytics functions automatically extract event patterns and recognize recurrent events in real time by analyzing collected data streams from different sources. A root cause analysis component analyzes the extracted events and identifies both correlation and causality relationships among different components to pinpoint root cause of a networked-system anomaly. Furthermore, an anomaly impact prediction component estimates the impact scope of the detected anomaly and raises early alarms about impending service outages or application performance degradations based on the identified correlation and causality relationships.

摘要： The present invention provides a computer implemented method, an apparatus, and a computer usable program product for indexing data. A controller identifies a set of data to be indexed, wherein a set of data structure trees represents the set of data. The controller merges the set of data structure trees to form a unified tree, wherein the unified tree contains a node for each unit of data in the set of data. The controller assigns an identifier to the node for each unit of data in the set of data that describes the node within the unified tree. The controller then serializes the unified tree to form a set of sequential series that represents the set of data structure trees, wherein the set of sequential series forms an index for the set of data.

摘要： Disclosed are a method, information processing system, and computer readable medium for managing data collection in a distributed processing system. The method includes dynamically collecting at least one statistical query pattern associated with a selected group of information processing nodes. The statistical query pattern is dynamically collected from a plurality of information processing nodes in a distributed processing system. At least one operating attribute distribution associated with an operating attribute that has been queried for the selected group is dynamically monitored. The selected group is dynamically configured, based on the query pattern and the operating attribute distribution, to periodically push a set of attributes associated with the each information processing node in the selected group.

摘要： A system, method, and computer program product for establishing multi-party VoIP conference audio calls in a distributed, peer-to-peer network where any number of nodes are able to arbitrarily and asynchronously start or stop producing audio output to be mixed into a single composite audio stream that is distributed to all nodes. A single distribution tree is used that has optimal communications characteristics to distribute the composite audio signal to all nodes. An audio mixing tree is established and maintained by adaptively and dynamically adding and merging intermediate mixing nodes operating between user nodes and the root of the single distribution tree. The intermediate mixing nodes and the root of the single distribution tree are all hosted, in an exemplary embodiment, on user nodes that are endpoints of the distribution tree.
