  • Patent number: 10374904
    Abstract: Systems, methods, and computer-readable media for network visualization. A system analyzes traffic associated with network elements and generates a graphical user interface (GUI). The GUI can include graphical segments representing the network elements and contiguously arranged in a first graphical structure. Each of the graphical segments can represent a category of network elements and indicate a number of network elements in the category. The GUI can also include a second set of graphical segments representing the network traffic and contiguously arranged in a second graphical structure. Each of the second set of graphical segments can represent a type of traffic associated with respective network elements and indicate an amount of traffic associated with the type of traffic. Moreover, the GUI can include visual indication(s) representing respective amounts of traffic for each specific type of traffic and/or an amount of bandwidth between the collector engine and a remote destination.

  • Patent number: 9965348
    Abstract: A computer optimizes the prospective generation of data used for analysis of a software problem. The computer generates data in accordance with data generation parameters and a software problem is analyzed with reference to the data so generated. The problem analysis produces a report that details specifics of the software problem, the data that was available for analysis, a flag to indicate success or failure of the analysis to identify a root cause, and information about whether the data supplied was insufficient, sufficient, or superfluous with respect to identifying a root cause of the software problem. The method then uses the analysis report to modify the data generation parameters, thereby iteratively optimizing the data that are generated for analysis of subsequent software problems.

  • Patent number: 9824114
    Abstract: Implementations are provided herein for the use of multiple threads in concurrently restriping files by maintaining multiple cursors for a single file. The cursors can be stored and tracked on disk in a mirrored data structure (“MDS”) extension block also referred to as a Cursor Extension Block. During a restripe operation, individual cursors stored in the delta-block portion of the MDS extension block will be updated using delta operations of a file system. The operating system kernel can maintain an in-memory version of the delta-block portion of the MDS extension block as well. The Cursor Extension Block associated with a file can store data representing the ending logical cluster number of the cursor, the current logical cluster number of the cursor, and a current cursor count for a file.

  • Patent number: 6947797
    Abstract: A system (830) and method (800) for diagnosing a malfunctioning machine. A fault event is selected (806) together with sequential operating parameter data (808) from a selectively focused time interval about the fault event for evaluation of a machine (810). The selectively focused time interval may include data occurring just before, just after, or spanning the fault event. Characterizing information such as slope, rate of change, and absolute sign of the data may be derived (809) from the operating parameter data over the selectively focused time interval and used in the diagnosis. The fault event and operating parameter data may be compared to existing cases in a case database (834). A set of rules (817) or candidate anomalies (841) may be executed over the operating parameter data to further improve the accuracy of the diagnosis.

  • Patent number: 6356885
    Abstract: A method of processing data such as alarms from a communications network, by alarm correlation, the network comprising entities which offer and receive services to and from each other, the method comprising the step of: adapting a virtual model (87) of the network according to events in the network. The model comprises a plurality of managed units (91,92) corresponding to the network entities, each of said units containing information about the services offered and received by its corresponding entity to and from other entities, and having associated knowledge based reasoning capacity such as rules, for adapting the model by adapting said information. When one of the managed units is notified of an event such as an alarm raised by its corresponding entity, the cause of the alarm is determined using the virtual model. The development and maintenance of rules is easier, and correlation quicker since the rules for each unit need not relate to all the other units.

  • Patent number: 5950181
    Abstract: In an apparatus and a method for detecting and assessing a spatially discrete dot pattern disposed in a multidimensional coordinate system, each dot in the pattern assumes at least two differentiatable status values. A measuring device records the coordinate values and status values of each dot of the multidimensional spatial dot pattern. A memory stores data that correspond to the recorded coordinate values and status values of each dot of the multidimensional spatial dot pattern. A computer into which the stored data are entered and in which a coordinate counter for each coordinate value of a coordinate axis is determined from the stored data, is associated with the memory. The value of the coordinate counter is formed from the number of detected dots of the coordinates that have a predetermined status value. A neural network is associated with the computer.
