Module Core_extended.Sys_utils.Cpu_use

A module for getting a process's CPU use.

type t

val get : ?pid:Core.Pid.t ‑> unit ‑> t

get returns a Cpu_use.t for the given pid or the current processes's pid, if none given. Note that the cpu_use given by this initial value will probably be invalid.

val update_exn : t ‑> unit

update_exn updates a Cpu_use.t. It will fail if the process no longer exists.

val cpu_use : t ‑> float

cpu_use gives an estimated CPU usage (between 0 and 1) in the time period between the last 2 calls to update_exn.

val resident_mem_use_in_kb : t ‑> float

val age : t ‑> Core.Time.Span.t

val fds : t ‑> int
