stapprobes.process − systemtap process probe points
This family of
probe points is used to probe the process activities. It
contains the following probe points:

Arguments:
task
a handle to the newly created process
new_pid
pid of the newly created process
process.start
Fires immediately before a new process begins execution.
Arguments:
N/A
process.exec
Fires whenever a process attempts to exec to a new program
Arguments:
filename
the path to the new executable
process.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
process.exit
Fires when a process terminates. This will always be followed by a process.release, though the latter may be delayed if the process waits in a zombie state.
Arguments:
code
the exit code of the process
process.release
Fires when a process is released from the kernel. This always follows a process.exit, though it may be delayed somewhat if the process waits in a zombie state.
