zen_api_utils.streaming.metrics

Pure throughput metrics for ZEN pixel-stream measurements.

Classes:

• IntervalResult –

  Throughput accumulated over one reporting interval.

Functions:

• calculate_interval –

  Calculate rates for an interval using monotonic nanosecond timestamps.

IntervalResult dataclass

IntervalResult(elapsed_seconds: float, interval_seconds: float, total_frames: int, interval_frames: int, total_bytes: int, interval_bytes: int, frames_per_second: float, mebibytes_per_second: float, megapixels_per_second: float, mean_reshape_microseconds: float)

Throughput accumulated over one reporting interval.

calculate_interval

calculate_interval(measurement_start_ns: int, interval_start_ns: int, now_ns: int, total_frames: int, interval_frames: int, total_bytes: int, interval_bytes: int, interval_pixels: int, interval_reshape_ns: int) -> IntervalResult

Calculate rates for an interval using monotonic nanosecond timestamps.
