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.

       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.
