NAME

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

SYNOPSIS

   trace-cmd stat

DESCRIPTION

   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.
