integer

required

Window the statistics cover.

object

required

{ offset_ns, rtt_ns, samples? } — the agent’s current clock-offset estimate and the round-trip time of the sample it came from (AWP-CLK-008).

object

required

Keyed by decimal channel_id: { frames, gaps, jitter_ns?, staleness_ns? }. gaps counts missing seq values; jitter_ns is the mean absolute variation of transit time between consecutive frames; staleness_ns is the distribution of staleness at receipt.

object

{ count, p50, p95, max? } from receipt of a basis frame to transmission of the submission built on it.

Sent at least every 5 s in streaming sessions (AWP-OBS-007). The world may lower a channel’s delivery rate in response, never above the negotiated rate. Definitions: latency and staleness.
