Implementations

impl CPUStat

pub fn compute_cpu_time(&self) -> CPUTime

Add all idle time and non-idle time respectively.

use mprober_lib::cpu;

let average_cpu_stat = cpu::get_average_cpu_stat().unwrap();
let cpu_time = average_cpu_stat.compute_cpu_time();

println!("{cpu_time:#?}");

pub fn compute_cpu_utilization_in_percentage( &self, cpu_stat_after_this: &CPUStat, ) -> f64

Compute CPU utilization in percentage between two CPUStat instances at different time. If it returns 1.0, means 100%.

use std::{thread::sleep, time::Duration};

use mprober_lib::cpu;

let pre_average_cpu_stat = cpu::get_average_cpu_stat().unwrap();

sleep(Duration::from_millis(100));

let average_cpu_stat = cpu::get_average_cpu_stat().unwrap();

let cpu_percentage = pre_average_cpu_stat
    .compute_cpu_utilization_in_percentage(&average_cpu_stat);

println!("{:.2}%", cpu_percentage * 100.0);
