Package sysfs provides functions to retrieve system and kernel metrics from the pseudo-filesystem sys.
Internal call graph ▹
Internal call graph ▾
In the call graph viewer below, each node is a function belonging to this package and its children are the functions it calls—perhaps dynamically.
The root nodes are the entry points of the package: functions that may be called from outside the package. There may be non-exported or anonymous functions among them if they are called dynamically from another package.
Click a node to visit that function's source code.
From there you can visit its callers by

Functions may be omitted if they were determined to be unreachable in the particular programs or tests that were analyzed.
DefaultMountPoint is the common mount point of the sys filesystem.
const DefaultMountPoint = "/sys"
FS represents the pseudo-filesystem sys, which provides an interface to kernel data structures.
type FS string
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) BcacheStats ¶
func (fs FS) BcacheStats() (*bcache.Stats, error)
BcacheStats retrieves bcache runtime statistics for each bcache.
func (fs FS) Path(p ...string) string
Path returns the path of the given subsystem relative to the sys root.
func (fs FS) XFSStats() (*xfs.Stats, error)
XFSStats retrieves XFS filesystem runtime statistics for each mounted XFS filesystem. Only available on kernel 4.4+. On older kernels, an empty slice of *xfs.Stats will be returned.
