Struct StorageStatistics

    pub logical_requests: u64,
    pub physical_requests: u64,

    pub completed_bytes: u64,
    pub errors: u64,

}

Measured session counters. Durations use host clocks, not GPU timestamps.

Fields

logical_requests: u64

Accepted logical requests, including shared reads.

physical_requests: u64

Native requests submitted to the kernel.

shared_reads: u64

Logical reads sharing an existing retained read.

completed_bytes: u64

Bytes from successful requests, including alignment padding.

errors: u64

Distinct requests ending in an error; shared tickets count once.

peak_slots: usize

Maximum simultaneously retained slots.

peak_outstanding: usize

Largest submitted batch (not NVMe hardware queue depth).

admission_time: Option<Duration>

Accumulated queue delay before GPU publication, when enabled.

ready_time: Option<Duration>

Accumulated submit-to-observed-completion time, when enabled.

service_cpu_time: Option<Duration>

Service thread CPU time, when supported and enabled.

service_calls: u64

Kernel enter calls: SQPOLL wakes or deferred-work service.

wait_calls: u64

Bounded eventfd waits.
