Function sys_metrics::cpu::get_cpufreq

pub fn get_cpufreq() -> Result<f64, Error>

Get the cpufreq as f64.

On linux it will return the first frequency it see from /proc/cpuinfo (key: cpu MHz).

And on macOS it will make a syscall which will return the cpufreq (macOS doesn't seems to have per-core clock).

Exemples

use sys_metrics::cpu::get_cpufreq;

let cpufreq: f64 = match get_cpufreq() {
    Ok(val) => val,
    Err(x) => panic!(x),
};

// Should print your cpufreq as mHz
println!("{}", cpufreq);
