Expand description

Aggregate summary of a stream run, produced by StreamMetrics::summary and passed to StreamObserver::on_finish.

Fields§

§num_requests: u64

Total completed requests.

§num_truncated: u64

Requests whose response was truncated before the requested end.

§truncation_rate: f64

num_truncated / num_requests (0 when no requests).

§total_bytes: u64

Sum of response body sizes.

§total_blocks: u64

Sum of blocks covered.

§wall_clock: Duration

Wall-clock span of the run (engine-fed when finished, else measured live from when the metrics handle was created).

§blocks_per_sec: f64

total_blocks / wall_clock (0 when no elapsed time).

§bytes_per_sec: f64

total_bytes / wall_clock (0 when no elapsed time).

§mean_size_ratio: f64

Mean size_ratio across requests.

§size_histogram: [u64; 6]

Size-vs-target histogram counts, see SIZE_BUCKET_LABELS.

§mean_bytes_per_block: f64

Mean density (total_bytes / total_blocks).

§min_blocks: u64

Smallest block-range size requested-and-covered.

§mean_blocks: f64

Mean covered block-range size (total_blocks / num_requests).

§max_blocks: u64

Largest block-range size covered.

§max_buffered_bytes_observed: u64

High-water mark of the undelivered reorder buffer, in bytes.

§mean_in_flight: f64

Mean number of in-flight requests across scheduler iterations.

§num_frontier: u64

Requests that extended the frontier.

§num_gap_fill: u64

Requests that backfilled a gap.
