lib.rs:

A tiny library to measure resource usage of the process it's used in. Currently it measures:

• Memory Usage
• CPU Usage with breakdown by each thread
• Disk Usage

More metrics might be added later. Currently, library supports only linux, but pull requests for other platforms are welcome.

Example

fn main() {
   let mut meter = self_meter::Meter::new(Duration::new(1, 0)).unwrap();
   meter.track_current_thread("main");
   loop {
       meter.scan()
           .map_err(|e| writeln!(&mut stderr(), "Scan error: {}", e)).ok();
       println!("Report: {:#?}", meter.report());
       println!("Threads: {:#?}",
           meter.thread_report().map(|x| x.collect::<BTreeMap<_,_>>()));
       // Put your task here
       // ...
       //
       sleep(Duration::new(1, 0));
   }
}
