Crate presutaoru 

presutaoru (ぷれすたおる)

A linux Pressure Stall Information (PSI) file descriptor wrapper / monitor library for Rust.

use presutaoru::{PsiFdBuilder, PsiEntry, StallType, PsiMonitor};
use std::time::Duration;

let psi_fd = PsiFdBuilder::default()
    .entry(presutaoru::PsiEntry::Cpu)
    .stall_type(presutaoru::StallType::Some)
    .stall_amount(Duration::from_micros(500))
    .time_window(Duration::from_secs(1))
    .build()
    .unwrap();

let mut monitor = PsiMonitor::default();
monitor.add_fd("psi_fd", psi_fd);
let mut thread = monitor.into_thread().unwrap();

while let Ok(event) = thread.recv() {
   println!("PSI Event: {:?}", event);
}

Structs

PsiFd

PsiFdBuilder

Builder for PsiFd

PsiMonitor

A monitor for multiple PSI file descriptors. Which does not implement any polling mechanism itself, but allows managing multiple PSI FDs conveniently.

PsiThread

PsiTokioReactor

Enums

Event

PsiEntry

PsiEntry types, it’s the path to /proc/pressure/type files.

PsiFdBuilderError

Errors that can occur when building a PsiFd
