Types

type ProcStats

type ProcStats struct {
	Utime     float64 // Amount of time that this process has been scheduled in user mode
	Stime     float64 // Amount of time that this process has been scheduled in kernel mode
	Cutime    float64 // Amount of time that this process's waited-for chil‐dren have been scheduled in user mode
	Cstime    float64 // Amount of time that this process's waited-for chil‐dren have been scheduled in kernel mode
	Rss       int     // Resident Set Size: number of pages the process has in real memory
	Starttime float64 // The time the process started after system boot
	// contains filtered or unexported fields
}
