    • Method Detail

      • getTimeWindow

        public long getTimeWindow()
        Description copied from interface: TimeWindowStatistics
        Returns the size of time window in milliseconds. Returned value denotes in how many last milliseconds the statistics are evaluated.
        Specified by:
        getTimeWindow in interface TimeWindowStatistics
        Returns:
        Time window in milliseconds.
      • getRequestsPerSecond

        public double getRequestsPerSecond()
        Description copied from interface: TimeWindowStatistics
        Returns average value of how many requests per second were received by application in the time window.
        Specified by:
        getRequestsPerSecond in interface TimeWindowStatistics
        Returns:
        Average of requests per second.
      • getMinimumDuration

        public long getMinimumDuration()
        Description copied from interface: TimeWindowStatistics
        Returns the minimum duration (processing time) in milliseconds of the request processing measured in the time window. The time measures the processing of the request since the start of request processing by Jersey until the response is written or request processing fails and all resources for request processing are released.
        Specified by:
        getMinimumDuration in interface TimeWindowStatistics
        Returns:
        Minimum processing time of the request or -1 if no request has been processed.
      • getMaximumDuration

        public long getMaximumDuration()
        Description copied from interface: TimeWindowStatistics
        Returns the maximum duration (processing time) in milliseconds of the request processing measured in the time window. processing of the request since the start of request processing by Jersey until the response is written or request processing fails and all resources for request processing are released.
        Specified by:
        getMaximumDuration in interface TimeWindowStatistics
        Returns:
        Maximum processing time of the request or -1 if no request has been processed.
      • getRequestCount

        public long getRequestCount()
        Description copied from interface: TimeWindowStatistics
        Returns the count of requests received measured in the time window.
        Specified by:
        getRequestCount in interface TimeWindowStatistics
        Returns:
        Count of requests that were handled by the application.
      • snapshot

        public TimeWindowStatistics snapshot()
        Description copied from interface: TimeWindowStatistics
        Get the immutable and consistent snapshot of the monitoring statistics. Working with snapshots might have negative performance impact as snapshot must be created but ensures consistency of data over time. However, the usage of snapshot is encouraged to avoid working with inconsistent data. Not all statistics must be updated in the same time on mutable version of statistics.
        Specified by:
        snapshot in interface TimeWindowStatistics
        Returns:
        Snapshot of time window statistics.
      • getAverageDuration

        public long getAverageDuration()
        Description copied from interface: TimeWindowStatistics
        Returns the average duration (processing time) in milliseconds of the request processing measured in the time window. The time measures the processing of the request since the start of request processing by Jersey until the response is written or request processing fails and all resources for request processing are released.
        Specified by:
        getAverageDuration in interface TimeWindowStatistics
        Returns:
        Average processing time of the request or -1 if no request has been processed.
