trace-cmd-stack(1)

NAME

   trace-cmd-stack - read, enable or disable Ftrace Linux kernel stack
   tracing.

SYNOPSIS

   trace-cmd stack

DESCRIPTION

   The trace-cmd(1) stack enables the Ftrace stack tracer within the
   kernel. The stack tracer enables the function tracer and at each
   function call within the kernel, the stack is checked. When a new
   maximum usage stack is discovered, it is recorded.

   When no option is used, the current stack is displayed.

   To enable the stack tracer, use the option --start, and to disable the
   stack tracer, use the option --stop. The output will be the maximum
   stack found since the start was enabled.

   Use --reset to reset the stack counter to zero.
