SYNOPSIS

9       trace-cmd stat
10

DESCRIPTION

12       The trace-cmd(1) stat displays the various status of the tracing
13       (ftrace) system. The status that it shows is:
14
15       Tracer: if one of the tracers (like function_graph) is active.
16       Otherwise nothing is displayed.
17
18       Events: Lists the events that are enable.
19
20       Event filters: Shows any filters that are set for any events
21
22       Function filters: Shows any filters for the function tracers
23
24       Graph functions: Shows any functions that the function graph tracer
25       should graph
26
27       Buffers: Shows the trace buffer size if they have been expanded. By
28       default, tracing buffers are in a compressed format until they are
29       used. If they are compressed, the buffer display will not be shown.
30
31       Trace clock: If the tracing clock is anything other than the default
32       "local" it will be displayed.
33
34       Trace CPU mask: If not all available CPUs are in the tracing CPU mask,
35       then the tracing CPU mask will be displayed.
36
37       Trace max latency: Shows the value of the trace max latency if it is
38       other than zero.
39
40       Kprobes: Shows any kprobes that are defined for tracing.
41
42       Uprobes: Shows any uprobes that are defined for tracing.
