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
