Expand description
This crate provides a high-level encapsulation of Linux’s per-task statistics interface.
Currently only limited information is exposed in Taskstats
struct,
but new field can be easily added for future version.
If there are any other fields in taskstats
struct useful to you,
feel free to submit PR to add them.
§Examples
Query aggregated taskstats of a task:
let mut conn = TaskstatsConnection::new()?;
let stats = conn.get_pid_stats(1)?;
// ...
Listen to taskstats of exited tasks:
let conn = TaskstatsConnection::new()?;
let cpu_mask = CString::new("0-7\0".to_owned()).unwrap().into_boxed_c_str();
let mut listener = TaskstatsListener::register(conn, cpu_mask)?;
loop {
let (pid, stats) = listener.get_next()?;
// ...
}
§Note
This crate only exposes stats for pid / task, but not tgid / process, because the kernel doesn’t really pass much useful information for tgid. It is recommended that you rely on pid stats and aggregate for process manually.
