Functions

func GetCgroupParamKeyValue

func GetCgroupParamKeyValue(t string) (string, uint64, error)

Parses a cgroup param and returns as name, value

i.e. "io_service_bytes 1234" will return as io_service_bytes, 1234

func GetCgroupParamString

func GetCgroupParamString(cgroupPath, cgroupFile string) (string, error)

Gets a string value from the specified cgroup file

func GetCgroupParamUint

func GetCgroupParamUint(cgroupPath, cgroupFile string) (uint64, error)

Gets a single uint64 value from the specified cgroup file.

func ParseUint

func ParseUint(s string, base, bitSize int) (uint64, error)

Saturates negative values at zero and returns a uint64. Due to kernel bugs, some of the memory cgroup stats can be negative.

func ReadFile

func ReadFile(dir, file string) (string, error)

func WriteFile

func WriteFile(dir, file, data string) error
