NAME         top

       trace-cmd-stat - show the status of the tracing (ftrace) system

SYNOPSIS         top

       trace-cmd stat

DESCRIPTION         top

       The trace-cmd(1) stat displays the various status of the tracing
       (ftrace) system. The status that it shows is:

       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.
