Constants 

const DefaultMountPoint = fs.DefaultSysMountPoint

DefaultMountPoint is the common mount point of the sys filesystem.

Types

type FS 

type FS struct {
	// contains filtered or unexported fields
}

FS represents the pseudo-filesystem sys, which provides an interface to kernel data structures.

func NewDefaultFS 

func NewDefaultFS() (FS, error)

NewDefaultFS returns a new FS mounted under the default mountPoint. It will error if the mount point can't be read.

func NewFS 

func NewFS(mountPoint string) (FS, error)

NewFS returns a new FS mounted under the given mountPoint. It will error if the mount point can't be read.

func (FS) CPUVulnerabilities 

func (fs FS) CPUVulnerabilities() ([]Vulnerability, error)

CPUVulnerabilities retrieves a map of vulnerability names to their mitigations.

func (FS) VMStatNUMA 

func (fs FS) VMStatNUMA() (map[int]VMStat, error)
