The status that it shows is: .sp \fBInstances:\fR List all configured ftrace instances\&. .sp \fBTracer:\fR if one of the tracers (like function_graph) is active\&. Otherwise nothing is displayed\&. .sp \fBEvents:\fR Lists the events that are enable\&. .sp \fBEvent filters:\fR Shows any filters that are set for any events .sp \fBFunction filters:\fR Shows any filters for the function tracers .sp \fBGraph functions:\fR Shows any functions that the function graph tracer should graph .sp \fBBuffers:\fR 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\&. .sp \fBTrace clock:\fR If the tracing clock is anything other than the default "local" it will be displayed\&. .sp \fBTrace CPU mask:\fR If not all available CPUs are in the tracing CPU mask, then the tracing CPU mask will be displayed\&. .sp \fBTrace max latency:\fR Shows the value of the trace max latency if it is other than zero\&. .sp \fBKprobes:\fR Shows any kprobes that are defined for tracing\&. .sp \fBUprobes:\fR Shows any uprobes that are defined for tracing\&. .sp \fBError log:\fR Dump the content of ftrace error_log file\&. .SH "SEE ALSO" .sp 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) .SH "AUTHOR" .sp Written by Steven Rostedt, <\m[blue]\fBrostedt@goodmis\&.org\fR\m[]\&\s-2\u[1]\d\s+2> .SH "RESOURCES" .sp git://git\&.kernel\&.org/pub/scm/linux/kernel/git/rostedt/trace\-cmd\&.git .SH "COPYING" .sp Copyright (C) 2014 Red Hat, Inc\&.
