  • Patent number: 10613922
    Abstract: An approach is provided for generating diagnostic data. In response to a determination that an error condition occurs in a first node executing a first process which restarts based on the error condition occurring, a first message is received, where the first message is broadcast from the first node to a second node and other node(s). In response to the first message, in-memory collections of diagnostic data are started in the nodes. Subsequent to receiving the first message, the error condition occurs in the second node. Based on the error condition occurring in the second node, a second message is broadcast from the second node to the first node and the other node(s) which causes the first node, the second node, and the other node(s) to dump the in-memory collections of diagnostic data at a predefined location.

A level of utilization of a first measurement interval of the device is estimated by: repeatedly updating the lower value and the upper value based, at least in part, on the level of utilization, until the lower value and the upper value differ less than a pre-determined threshold; and determining an estimated level of utilization based, at least in part, on the lower value and the upper value. The estimated level of utilization is reported.

  • Patent number: 9880915
    Abstract: Input sequence information may be analyzed and quantified using n-gram analysis of inputs received by an application. The sequences of inputs may be represented by n-grams, and the frequency of the various n-grams may indicate the ‘real world’ uses of the application in production, which may be compared to a test suite whose coverage may be quantified using a similar n-gram analysis. A coverage factor may compare the observed inputs to the application in production to the test suite for the application. The n-grams may be further quantified or prioritized by resource utilization and several visualizations may be generated from the data.

  • Patent number: 9811444
    Abstract: A test system registers a series of tests that reference different software enhancements added to an application within a database system. The test system enables individual software enhancements referenced by the tests and then runs log lines through the application to produce test structured query language (SQL). The database system compares the test SQL with baseline SQL produced by the application without enabling the software enhancements. The database system executes the test SQL and captures performance metrics when the test SQL is different from the baseline SQL. Comparing SQL results avoids processing and capturing performance metrics for log lines not affected by the software enhancements. Incrementally running the log lines with one software enhancement enabled at a time also allows the test system to isolate the performance impact of individual software enhancements on the database system.

  • Patent number: 9804949
    Abstract: Periodicity similarity between two different tracer objectives may be used to identify additional input parameters to sample. The tracer objectives may be individual portions of a large tracer operation, and each of the tracer objectives may have separate set of input objects for which data may be collected. After collecting data for a tracer objective, other tracer objectives with similar periodicities may be identified. The input objects from the other tracer objectives may be added to a tracer objective and the tracer objective may be executed to determine a statistical significance of the newly added objective. An iterative process may traverse multiple input objects until exhausting possible input objects and a statistically significant set of input objects are identified.

  • Patent number: 9760470
    Abstract: An application list reading part 220 reads an application list 122. An application collecting part 230 acquires a source code 111 of an installed application indicated by the application list 122. The application collecting part 230 also acquires a source code 111 of an additional application. A program analyzing part 240 performs program analysis concerning a new execution program 123 using the source codes 111. If a bug will not occur in the new execution program 123, a program creating part 250 creates a new execution program 123. Then, a program updating part 260 writes the new execution program 123 to an electronic control device 121 and adds an additional application name to the application list 122.

  • Patent number: 9594662
    Abstract: Methods for automatically identifying and instrumenting application classes and methods for a particular application are described. In some embodiments, application code (e.g., bytecode or source code) associated with the particular application may be parsed to identify classes and methods within the application code and to identify terminal components (e.g., methods or function calls) and non-terminal components (e.g., control flow statements). Once the terminal components and non-terminal components have been identified, a complexity model and a corresponding score for each of the classes and methods within the application code may be determined. The complexity model may be used to estimate the number of computations that may be required if a particular class or method is used by the particular application. Application classes and methods corresponding with a score that is greater than a threshold may be instrumented by inserting probes into the identified classes and methods.
