  • Publication number: 20180365571
    Abstract: A real-time data monitoring system includes a converging time-series generation component to analyze historical data of a time-series to determine converging times for data points of the time-series at various times of a day. Each converging time indicates a predicted amount of time for the respective data point of the time-series to converge. The converging time-series generation component then generates a converging time-series which pairs the converging times with respective timestamps. A data retrieval component of the real-time data monitoring system is configured to dynamically adjust a retrieval time for data points of the time-series based on the converging times of the converging time-series, and retrieve each data point of the time-series at the determined retrieval time from one or more data sources. The real-time data monitoring system processes the retrieved data points of the time-series to generate one or more real-time alerts.
