Struct ProcessIo 

pub struct ProcessIo {
    pub read: MetricState<Rate>,
    pub write: MetricState<Rate>,
    pub read_total_bytes: MetricState<u64>,
    pub write_total_bytes: MetricState<u64>,
}

Per-process disk I/O.

Requires /proc/<pid>/io on Linux (often permission-restricted for other users’ processes) and privileged access on macOS, so it is frequently MetricState::PermissionDenied rather than zero.

Fields

read: MetricState<Rate>

Read throughput.

write: MetricState<Rate>

Write throughput.

read_total_bytes: MetricState<u64>

Cumulative bytes read since the process started.

write_total_bytes: MetricState<u64>

Cumulative bytes written since the process started.

Implementations

impl ProcessIo

pub const UNSUPPORTED: Self

A value for a platform that cannot report per-process I/O at all.

pub const WARMING_UP: Self

A value whose counters exist but whose rates need a second sample.
