SYNOPSIS

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       Instances: List all configured ftrace instances.
16
17       Tracer: if one of the tracers (like function_graph) is active.
18       Otherwise nothing is displayed.
19
20       Events: Lists the events that are enable.
21
22       Event filters: Shows any filters that are set for any events
23
24       Function filters: Shows any filters for the function tracers
25
26       Graph functions: Shows any functions that the function graph tracer
27       should graph
28
29       Buffers: Shows the trace buffer size if they have been expanded. By
30       default, tracing buffers are in a compressed format until they are
31       used. If they are compressed, the buffer display will not be shown.
32
33       Trace clock: If the tracing clock is anything other than the default
34       "local" it will be displayed.
35
36       Trace CPU mask: If not all available CPUs are in the tracing CPU mask,
37       then the tracing CPU mask will be displayed.
38
39       Trace max latency: Shows the value of the trace max latency if it is
40       other than zero.
41
42       Kprobes: Shows any kprobes that are defined for tracing.
43
44       Uprobes: Shows any uprobes that are defined for tracing.
45
46       Error log: Dump the content of ftrace error_log file.
