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 GetCgroupParamKeyValue ¶

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

GetCgroupParamKeyValue parses a space-separated "name value" kind of cgroup parameter and returns its components. For example, "io_service_bytes 1234" will return as "io_service_bytes", 1234.

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 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, cgroup *configs.Cgroup) error

RdmaSet sets RDMA resources.
