Fields

syscall_reads: u64

Ordinary positional reads selected by a warm-cohort NOWAIT hit.

syscall_writes: u64

Nonempty logical writes sent to the synchronous syscall executor.

cache_probes: u64

Synchronous RWF_NOWAIT read attempts, excluding ring fallback work.

cache_hits: u64

Requests completely satisfied by synchronous RWF_NOWAIT probes.

cache_misses: u64

Requests routed to the ring by cache-read selection.

waves: u64

submissions: u64

completions: u64

peak_bytes: u64

enters: u64

Calls to io_uring_enter, including interrupted attempts.

scratch_growths: u64

copied_read_bytes: u64

Bytes copied from scratch into borrowed read destinations.
