    Abstract: A bottleneck detector may analyze individual workloads processed by an application by logging times when the workload may be processed at different checkpoints in the application. For each checkpoint, a curve fitting algorithm may be applied, and the fitted curves may be compared between different checkpoints to identify bottlenecks or other poorly performing sections of the application. A real time implementation of a detection system may compare newly captured data points against historical curves to detect a shift in the curve, which may indicate a bottleneck. In some cases, the fitted curves from neighboring checkpoints may be compared to identify sections of the application that may be a bottleneck. An automated system may apply one set of checkpoints in an application, identify an area for further investigation, and apply a second set of checkpoints in the identified area. Such a system may recursively search for bottlenecks in an executing application.

    Abstract translation: 瓶颈检测器可以通过在应用程序的不同检查点处处理工作负载的记录时间来分析应用程序处理的各个工作负载。 对于每个检查点，可以应用曲线拟合算法，并且可以在不同检查点之间比较拟合曲线，以识别应用程序的瓶颈或其他性能差的部分。 检测系统的实时实现可以将新捕获的数据点与历史曲线进行比较，以检测曲线中的偏移，这可能表示瓶颈。 在某些情况下，可以比较来自相邻检查点的拟合曲线以识别应用程序可能是瓶颈的部分。 自动化系统可以在应用程序中应用一组检查点，识别进一步调查的区域，并在识别的区域中应用第二组检查点。 这样的系统可以递归地搜索执行应用程序中的瓶颈。

    Abstract: A data analysis system processes data generated by instrumented software. The data analysis system receives data streams generated by instances of instrumented software executing on systems. The data analysis system also receives metadata describing data streams. The data analysis system receives an expression based on the metadata. The data analysis system receives data of data streams for each time interval and computes the result of the expression based on the received data values. The data analysis system repeats these steps for each time interval. The data analysis system may quantize data values of data streams for each time interval by generating an aggregate value for the time interval based on data received for each data stream for that time interval. The data analysis system evaluates the expression using the quantized data for the time interval.

    Abstract: According to aspects of the invention there are provided methods and apparatus for monitoring, analysing and/or optimising the performance of a mobile device. The mobile device includes a memory with computer readable instructions stored thereon associated with a diagnostic application, which when executed on a processor, has a first level of permissions for accessing the mobile device, and associated with a performance monitoring component, which when executed on the processor, has a second level of permissions for accessing the mobile device. The diagnostic application and performance monitoring component communicate to retrieve performance-related data associated with execution of an application on the mobile device, where the performance-related data is accessible using the second level of permissions. The diagnostic application receives and stores performance related data from the performance monitoring component for analysing and/or optimising the performance of the mobile device executing the application.

    Abstract: A detecting system includes a sense terminal and detecting circuitry coupled to the sense terminal. The sense terminal receives an indicative signal indicative of a supply current of a power source. The detecting circuitry calculates variation in the supply current based on the indicative signal, estimates power consumption of an application program residing on a computer-readable medium according to the variation, and detects whether an abnormal condition occurs by comparing the estimated power consumption with a reference.

    Abstract: A method for automated parallel testing of a software application using value replication is disclosed. An example embodiment may include marking at least one event in the software application with a primary marker that includes a primary marker label and a primary marker configuration value. The primary marker may be replicated to create a replicate marker that has a replicate marker label and a replicate configuration value. The replicate marker label and configuration value may be different from the primary marker label and configuration value. Parallel executions of the software application may be performed using the primary and replicate markers so that the software application is executed with both the primary and replicate marker configuration values. The disclosed middleware-level method transparently implements such replication of the output marker values. That is to make any MapReduce-style applications easily take advantage of output value replication.
