Struct freebsd_libgeom::Statistics

pub struct Statistics<'a> { /* private fields */ }

Computes statistics between two Snapshots for the same device.

This is equivalent to libgeom’s devstat_compute_statistics function.

Implementations

impl<'a> Statistics<'a>

pub fn compute( current: Devstat<'a>, previous: Option<Devstat<'a>>, etime: f64 ) -> Self

Compute statistics between two Devstat objects, which must correspond to the same device, and should come from two separate snapshots

If prev is None, then statistics since boot will be returned. etime should be the elapsed time in seconds between the two snapshots.

pub fn busy_time(&self) -> f64

pub fn busy_pct(&self) -> f64

The percentage of time the device had one or more transactions outstanding between the acquisition of the two snapshots.

pub fn queue_length(&self) -> u32

Returns the number of incomplete transactions at the time cur was acquired.
