Functions ¶

func GetCgroupParamInt ¶

func GetCgroupParamInt(path, file string) (int64, error)

GetCgroupParamInt reads a single int64 value from specified cgroup file. If the value read is "max", the math.MaxInt64 is returned.

func GetCgroupParamString ¶

func GetCgroupParamString(path, file string) (string, error)

GetCgroupParamString reads a string from the specified cgroup file.

func GetCgroupParamUint ¶

func GetCgroupParamUint(path, file string) (uint64, error)

GetCgroupParamUint reads a single uint64 value from the specified cgroup file. If the value read is "max", the math.MaxUint64 is returned.

func GetValueByKey ¶

func GetValueByKey(path, file, key string) (uint64, error)

GetValueByKey reads a key-value pairs from the specified cgroup file, and returns a value of the specified key. ParseUint is used for value conversion.

func ParseKeyValue ¶

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

ParseKeyValue parses a space-separated "name value" kind of cgroup parameter and returns its key as a string, and its value as uint64 (ParseUint is used to convert the value). For example, "io_service_bytes 1234" will be returned as "io_service_bytes", 1234.

func ParseUint ¶

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

ParseUint converts a string to an uint64 integer. Negative values are returned at zero as, due to kernel bugs, some of the memory cgroup stats can be negative.

func RdmaGetStats ¶

func RdmaGetStats(path string, stats *cgroups.Stats) error

RdmaGetStats returns rdma stats such as totalLimit and current entries.

func RdmaSet ¶

func RdmaSet(path string, r *configs.Resources) error

RdmaSet sets RDMA resources.

Types ¶

type ParseError ¶

type ParseError struct {
	Path string
	File string
	Err  error
}

ParseError records a parse error details, including the file path.

func (*ParseError) Error ¶

func (e *ParseError) Error() string

func (*ParseError) Unwrap ¶

func (e *ParseError) Unwrap() error
