PROBE::SYSCALL_ANY(3stap)   Syscall Any TapsetPROBE::SYSCALL_ANY(3stap)

NAME        top

       probe::syscall_any.return - Record exit from a syscall

SYNOPSIS        top

       syscall_any.return

VALUES        top

syscall_nr           number of the syscallname           name of the syscallretval           return value of the syscall

CONTEXT        top

       The process performing the syscall

DESCRIPTION        top

       The syscall_any.return probe point is designed to be a low       overhead that monitors all the syscalls returns via a kernel       tracepoint. Because of the breadth of syscalls it monitors it       provides no information about the syscall arguments, argstr string       representation of those arguments, or a string interpretation of       the return value (retval).       This requires kernel 3.5+ and newer which have the       kernel.trace(“sys_exit”) probe point.
