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. + +SEE ALSO +-------- +trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), +trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1), +trace-cmd-list(1), trace-cmd-listen(1) + +AUTHOR +------ +Written by Steven Rostedt, <rostedt@goodmis.org> + +RESOURCES +--------- +https://git.kernel.org/pub/scm/utils/trace-cmd/trace-cmd.git/ + +COPYING +------- +Copyright \(C) 2010 Red Hat, Inc.
