tapset::kprocess

TAPSET::KPROCESS(3stap) 												   TAPSET::KPROCESS(3stap)

NAME

       tapset::kprocess - systemtap kernel process probe points

DESCRIPTION

       This family of probe points is used to probe the kernel's process activities.  It contains the following probe points:

       kprocess.create

	      Fires  whenever  a  new  process	is  successfully  created, either as a result of one of the fork syscall variants, or a new kernel
	      thread.

	      Arguments:

	      task
		a handle to the newly created process

	      new_pid
		pid of the newly created process

       kprocess.start

	      Fires immediately before a new process begins execution.

	      Arguments:

	      N/A

       kprocess.exec

	      Fires whenever a process attempts to exec to a new program

	      Arguments:

	      filename
		the path to the new executable

       kprocess.exec_complete

	      Fires at the completion of an exec call

	      Arguments:

	      errno
		the error number resulting from the exec

	      success
		a boolean indicating whether the exec was successful

       kprocess.exit

	      Fires when a process terminates. This will always be followed by a kprocess.release, though the latter may be delayed if the process
	      waits in a zombie state.

	      Arguments:

	      code
		the exit code of the process

       kprocess.release

	      Fires  when  a  process  is  released from the kernel. This always follows a kprocess.exit, though it may be delayed somewhat if the
	      process waits in a zombie state.

	      Arguments:

	      task
		a task handle to the process being released

	      pid
		pid of the process being released
