NAME

SYNOPSIS
--------

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

nothing is displayed.

*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.
*Error log:* Dump the content of ftrace error_log file.
