Описание (Description)

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.
