Types ¶

type ProcInfo ¶

type ProcInfo struct {
	Pid        int32
	Ppid       int32
	Command    string
	Status     string
	CpuUser    float64 // cumulative user CPU seconds; -1 if unavailable
	CpuSys     float64 // cumulative system CPU seconds; -1 if unavailable
	VmRSS      int64   // resident set size in bytes; -1 if unavailable
	Uid        uint32
	NumThreads int32 // -1 if unavailable
}

ProcInfo holds per-process information read from the OS. CpuUser and CpuSys are cumulative CPU seconds since process start; callers should diff two samples over a known interval to derive a rate. CpuUser, CpuSys, and VmRSS are set to -1 when the data is unavailable (e.g. permission denied reading another user's process).

func GetProcInfo ¶

func GetProcInfo(_ context.Context, _ any, pid int32) (*ProcInfo, error)

GetProcInfo reads process information for the given pid from /proc. It reads /proc/[pid]/stat for most fields and /proc/[pid]/status for the UID.
