NAME

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

SYNOPSIS

10       trace-cmd stack
11

DESCRIPTION

13       The trace-cmd(1) stack enables the Ftrace stack tracer within the
14       kernel. The stack tracer enables the function tracer and at each
15       function call within the kernel, the stack is checked. When a new
16       maximum usage stack is discovered, it is recorded.
17
18       When no option is used, the current stack is displayed.
19
20       To enable the stack tracer, use the option --start, and to disable the
21       stack tracer, use the option --stop. The output will be the maximum
22       stack found since the start was enabled.
23
24       Use --reset to reset the stack counter to zero.
25
26       User --verbose[=level] to set the log level. Supported log levels are
27       "none", "critical", "error", "warning", "info", "debug", "all" or their
28       identifiers "0", "1", "2", "3", "4", "5", "6". Setting the log level to
29       specific value enables all logs from that and all previous levels. The
30       level will default to "info" if one is not specified.
