Types ¶
type FileSystem ¶
type FileSystem struct {
MountPoint string
// contains filtered or unexported fields
}
FileSystem represents data accessible through the proc pseudo-filesystem.
func NewFileSystem ¶
func NewFileSystem(mountPoint string) (*FileSystem, error)
NewFileSystem returns a new concrete procfs FileSystem instance attached to the specified mount point. If the mount point is unspecified, the shared instance for the default /proc mount point is returned.
func (*FileSystem) BootID ¶
func (fs *FileSystem) BootID() string
BootID returns the kernel's boot identifier retrieved from the file sys/kernel/random/boot_id.
func (*FileSystem) HostFileSystem ¶
func (fs *FileSystem) HostFileSystem() proc.FileSystem
HostFileSystem returns a FileSystem representing the underlying host's procfs from the perspective of the active proc.FileSystem. If the calling process is running in the host pid namespace, the receiver may return itself. If the calling process is running in a container and no host proc filesystem is mounted in, the return will be nil. If cgroups are not enabled on the system, the host filesystem is the same as the calling filesystem.
func (*FileSystem) KernelTextSymbolNames ¶
func (fs *FileSystem) KernelTextSymbolNames() (map[string]string, error)
KernelTextSymbolNames returns a mapping of kernel symbols in the text segment. For each symbol in the map, the key is the source name for the symbol, and the value is the actual linker name that should be used for things like kprobes.
func (*FileSystem) MaxPID ¶
func (fs *FileSystem) MaxPID() uint
MaxPID returns the maximum PID that the kernel will use.
func (*FileSystem) Mounts ¶
func (fs *FileSystem) Mounts() []proc.Mount
Mounts returns the list of currently mounted filesystems.
func (*FileSystem) NumCPU ¶
func (fs *FileSystem) NumCPU() int
NumCPU returns the number of CPUs on the system. This differs from runtime.NumCPU in that runtime.NumCPU returns the number of logical CPUs available to the calling process.
func (*FileSystem) PerfEventDir ¶
func (fs *FileSystem) PerfEventDir() string
PerfEventDir returns the perf_event cgroup mountpoint to use to monitor specific cgroups. Return the empty string if no perf_event cgroup filesystem is mounted.
func (*FileSystem) ProcessCommandLine ¶
func (fs *FileSystem) ProcessCommandLine(pid int) ([]string, error)
ProcessCommandLine returns the full command-line arguments for the process indicated by the given PID.
func (*FileSystem) ProcessContainerID ¶
func (fs *FileSystem) ProcessContainerID(pid int) (string, error)
ProcessContainerID returns the container ID running the specified process. If the process is not running inside of a container, the return will be the empty string.
func (*FileSystem) ProcessExecutable ¶
func (fs *FileSystem) ProcessExecutable(pid int) (string, error)
ProcessExecutable returns the name of the executable from exe file
func (*FileSystem) ProcessMappings ¶
func (fs *FileSystem) ProcessMappings(pid int) ([]proc.MemoryMapping, error)
ProcessMappings returns the memory mappings a process currently has
func (*FileSystem) ReadFile ¶
func (fs *FileSystem) ReadFile(relativePath string) ([]byte, error)
ReadFile returns the contents of the procfs file indicated by the given relative path.
func (*FileSystem) ReadFileOrPanic ¶
func (fs *FileSystem) ReadFileOrPanic(relativePath string) []byte
ReadFileOrPanic returns the contents of the procfs file indicated by the given relative path. If the file cannot be read, glog.Fatal will be called.
func (*FileSystem) ReadTaskStatus ¶
func (fs *FileSystem) ReadTaskStatus(tgid, pid int, i interface{}) error
ReadTaskStatus reads the status of a task, storing the information into the supplied struct. The supplied struct must be a pointer.
func (*FileSystem) SelfTGID ¶
func (fs *FileSystem) SelfTGID() int
SelfTGID returns the TGID of the calling task.
func (*FileSystem) SupportedFilesystems ¶
func (fs *FileSystem) SupportedFilesystems() []string
SupportedFilesystems returns a list of filesystem types supported by the system.
func (*FileSystem) TaskCWD ¶
func (fs *FileSystem) TaskCWD(tgid, pid int) (string, error)
TaskCWD returns the current working directory for the specified task.
func (*FileSystem) TaskControlGroups ¶
func (fs *FileSystem) TaskControlGroups(tgid, pid int) ([]proc.ControlGroup, error)
TaskControlGroups returns the cgroup membership of the specified task.
func (*FileSystem) TaskStartTime ¶
func (fs *FileSystem) TaskStartTime(tgid, pid int) (int64, error)
TaskStartTime returns the time at which the specified task started.
func (*FileSystem) TaskUniqueID ¶
func (fs *FileSystem) TaskUniqueID(tgid, pid int, startTime int64) string
TaskUniqueID returns a unique task ID for a PID.
func (*FileSystem) TracingDir ¶
func (fs *FileSystem) TracingDir() string
TracingDir returns the tracefs mountpoint to use to control the Linux kernel trace event subsystem. Returns the empty string if no tracefs filesystem is mounted.
func (*FileSystem) WalkTasks ¶
func (fs *FileSystem) WalkTasks(walkFunc proc.TaskWalkFunc) error
WalkTasks calls the specified function for each task present in the proc FileSystem. If the walk function returns false, the walk will be aborted.
