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.

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.
