The status that it shows is: + +*Instances:* List all configured ftrace instances. + +*Tracer:* if one of the tracers (like function_graph) is active. Otherwise + nothing is displayed. + +*Events:* Lists the events that are enable. + +*Event filters:* Shows any filters that are set for any events + +*Function filters:* Shows any filters for the function tracers + +*Graph functions:* Shows any functions that the function graph tracer should graph + +*Buffers:* Shows the trace buffer size if they have been expanded. + By default, tracing buffers are in a compressed format until they are used. + If they are compressed, the buffer display will not be shown. + +*Trace clock:* If the tracing clock is anything other than the default "local" + it will be displayed. + +*Trace CPU mask:* If not all available CPUs are in the tracing CPU mask, then + the tracing CPU mask will be displayed. + +*Trace max latency:* Shows the value of the trace max latency if it is other than zero. + +*Kprobes:* Shows any kprobes that are defined for tracing. + +*Uprobes:* Shows any uprobes that are defined for tracing. + +*Error log:* Dump the content of ftrace error_log file. + +OPTIONS +------- +*-B* 'buffer-name':: + Display the status of a given buffer instance. May be specified more than once + to display the status of multiple instances. + +*-t*:: + If *-B* is also specified, show the status of the top level tracing directory + as well as the instance(s). + +*-o*:: + Display the all the options along with their values. If they start with "no", then + the option is disabled. + +SEE ALSO +-------- +trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), +trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1), +trace-cmd-split(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) 2014 Red Hat, Inc.
