TRACE-CMD-STACK(1)          libtracefs Manual          TRACE-CMD-STACK(1)

NAME         top

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

SYNOPSIS         top

       trace-cmd stack

DESCRIPTION         top

       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.

       User --verbose[=level] to set the log level. Supported log levels
       are "none", "critical", "error", "warning", "info", "debug", "all"
       or their identifiers "0", "1", "2", "3", "4", "5", "6". Setting
       the log level to specific value enables all logs from that and all
       previous levels. The level will default to "info" if one is not
       specified.
