17// Example:
18//
19// package main
20//
21// import (
22// "fmt"
23// "log"
24//
25// "github.com/prometheus/procfs"
26// )
27//
28// func main() {
29// p, err := procfs.Self()
30// if err != nil {
31// log.Fatalf("could not get process: %s", err)
32// }
33//
34// stat, err := p.NewStat()
35// if err != nil {
36// log.Fatalf("could not get process stat: %s", err)
37// }
38//
39// fmt.Printf("command: %s\n", stat.Comm)
40// fmt.Printf("cpu time: %fs\n", stat.CPUTime())
41// fmt.Printf("vsize: %dB\n", stat.VirtualMemory())
42// fmt.Printf("rss: %dB\n", stat.ResidentMemory())
43// }
