trace-cmd-stat - show the status of the tracing (ftrace) system
trace-cmd stat
The trace-cmd(1) stat displays the various status of the tracing (ftrace) system. 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.
