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.
