Metal Performance HUD

[Angelk90]

Hi @JakkuSakura , congrats on a great job.

Could you post an example of an animated graph like this, I don't know what it shows the cpu usage used by the same program started.

Registrazione.schermo.2025-01-08.alle.18.46.56.mov

use sysinfo::{System, Pid, ProcessesToUpdate};
use std::{thread, time};
fn main() {
    let mut sys = System::new_all();
    let pid = Pid::from(std::process::id() as usize);
    loop {
        sys.refresh_processes(ProcessesToUpdate::All, false);
        if let Some(process) = sys.process(pid) {
            let cpu_usage = process.cpu_usage();
            println!("CPU usage: {:.2}%", cpu_usage);
        } else {
            println!("Process with PID {} not found.", pid);
        }
        thread::sleep(time::Duration::from_millis(500));
    }
}

I believe the graph is called Metal Performance HUD

MTL_HUD_ENABLED=1
Enables the Metal Performance HUD.

MTL_HUD_ENABLED=1 cargo run ...

Will enable it

@JakkuSakura : What I mean is if you can create an animated graph similar to that.
I don't mean exactly the one you see in the video.
But a graph that allows you to show something similar.

[JakkuSakura]

See examples/animation-cpu.rs

@JakkuSakura : Why does it do this in some places?
It almost seems like some sort of defect.

Maybe a scale issue?

Finally after a while, the program crashed:

[JakkuSakura]

It's a rendering precision issue. There's an open PR pending that could fix this.

I'll double check the crash soon

[Angelk90]

@JakkuSakura : There shouldn't be time on the x-axis, right?

But it seems to give problems, after a while it resets again.

[JakkuSakura]

I'm not sure how to render time on x axis property, so I converted time difference to f32.

[JakkuSakura]

Finally after a while, the program crashed: SystemTime error

Maybe at this time your MacBook synced time with NTP and SystemTime reversed
