Functions

func NewEventStream

func NewEventStream() (*stream.Stream, error)

NewEventStream creates a new system-wide process event stream.

func NewEventStreamForCgroup

func NewEventStreamForCgroup(name string) (*stream.Stream, error)

NewEventStreamForCgroup creates a new process event stream for the cgroup of the given name. The named cgroup must exist under /sys/fs/cgroup/perf_event.

func NewEventStreamForPid

func NewEventStreamForPid(pid int) (*stream.Stream, error)

NewEventStreamForPid creates a new process event stream rooted at the process with the given pid.

func NewEventStreamForPidAndCPU

func NewEventStreamForPidAndCPU(pid int, cpu int) (*stream.Stream, error)

NewEventStreamForPidAndCPU creates a new process event stream for the specified pid and cpu numbers. When run from within a container, the process events for processes within a container contain the host process ids.
