TRACE-CMD-STACK(1) libtracefs Manual 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.
