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.
