Module level 

2026-09-26: The telemetry Level and the validated TelemetryConfig.

Serving takes the level from --telemetry and the NVML device from --gpu-ordinal; the cadences are the constants below, through TelemetryConfig::serving.

Owner: telemetry. Invariants: a TelemetryConfig’s device period lies in MIN_DEVICE_PERIOD..=MAX_DEVICE_PERIOD and its kernel span stride is at least 1.

Structs

TelemetryConfig

2026-09-26: A validated telemetry configuration. Its fields are private, and TelemetryConfig::new (which serving calls) is the only constructor.

Enums

ConfigError

2026-09-26: Why a level or configuration was refused.

Level

2026-09-26: The measurement level. Each level measures everything the levels below it measure.

Constants

DEVICE_SAMPLE_PERIOD

2026-09-26: Device sampling cadence when serving: 10 Hz.

KERNEL_SPAN_EVERY

2026-09-26: When serving at level Kernel, per-kernel spans are recorded on one step in this many.

MAX_DEVICE_PERIOD

2026-09-26: The longest device period TelemetryConfig::new accepts.

MIN_DEVICE_PERIOD

2026-09-26: The shortest device period TelemetryConfig::new accepts.
