остановить трассировщик ядра Ftrace Linux от записи в кольцевой буфер (stop the Ftrace Linux kernel tracer from writing to the ring buffer.)
Имя (Name)
trace-cmd-stop - stop the Ftrace Linux kernel tracer from writing
to the ring buffer.
Синопсис (Synopsis)
trace-cmd stop
[OPTIONS]
Описание (Description)
The trace-cmd(1) stop is a complement to trace-cmd-start(1). This
will disable Ftrace from writing to the ring buffer. This does
not stop the overhead that the tracing may incur. Only the
updating of the ring buffer is disabled, the Ftrace tracing may
still be inducing overhead.
After stopping the trace, the trace-cmd-extract(1) may strip out
the data from the ring buffer and create a trace.dat file. The
Ftrace pseudo file system may also be examined.
To disable the tracing completely to remove the overhead it
causes, use trace-cmd-reset(1). But after a reset is performed,
the data that has been recorded is lost.
Параметры (Options)
-B
buffer-name
If the kernel supports multiple buffers, this will stop the
trace for only the given buffer. It does not affect any other
buffer. This may be used multiple times to specify different
buffers. When this option is used, the top level instance
will not be stopped unless -t
is given.
-a
Stop the trace for all existing buffer instances. When this
option is used, the top level instance will not be stopped
unless -t
is given.
-t
Stops the top level instance buffer. Without the -B
or -a
option this is the same as the default. But if -B
or -a
is
used, this is required if the top level instance buffer
should also be stopped.
