trace-cmd-stop - stop the Ftrace Linux kernel tracer from writing to the ring buffer.
trace-cmd stop [OPTIONS]
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.
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
Stop the trace for all existing buffer instances. When this option is used, the top level instance will not be stopped unless
Stops the top level instance buffer. Without the
option this is the same as the default. But if
is used, this is required if the top level instance buffer should also be stopped.
