Implementations

impl ProcessTimeStat

pub fn compute_cpu_utilization_in_percentage(
    &self,
    process_time_stat_after_this: &ProcessTimeStat,
    total_cpu_time: f64
) -> f64

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

extern crate mprober_lib;

use std::thread::sleep;
use std::time::Duration;

use mprober_lib::cpu;
use mprober_lib::process;

let pre_average_cpu_stat = cpu::get_average_cpu_stat().unwrap();
let pre_process_time_stat = process::get_process_time_stat(1).unwrap();

sleep(Duration::from_millis(100));

let average_cpu_stat = cpu::get_average_cpu_stat().unwrap();
let process_time_stat = process::get_process_time_stat(1).unwrap();

let total_cpu_time_f64 = {
    let pre_average_cpu_time = pre_average_cpu_stat.compute_cpu_time();
    let average_cpu_time = average_cpu_stat.compute_cpu_time();

    (average_cpu_time.get_total_time() - pre_average_cpu_time.get_total_time()) as f64
};

let cpu_percentage = pre_process_time_stat
    .compute_cpu_utilization_in_percentage(&process_time_stat, total_cpu_time_f64);

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