trace-cmd-reset
TRACE-CMD-RESET(1)TRACE-CMD-RESET(1)NAME
trace-cmd-reset - turn off all Ftrace tracing to bring back full performance
SYNOPSIS
trace-cmd reset [OPTIONS]
DESCRIPTION
The trace-cmd(1) reset command turns off all tracing of Ftrace. This will bring back the performance of the system before tracing was
enabled. This is necessary since trace-cmd-record(1), trace-cmd-stop(1) and trace-cmd-extract(1) do not disable the tracer, event after the
data has been pulled from the buffers. The rational is that the user may want to manually enable the tracer with the Ftrace pseudo file
system, or examine other parts of Ftrace to see what trace-cmd did. After the reset command happens, the data in the ring buffer, and the
options that were used are all lost.
OPTIONS -b buffer_size
When the kernel boots, the Ftrace ring buffer is of a minimal size (3 pages per CPU). The first time the tracer is used, the ring
buffer size expands to what it was set for (default 1.4 Megs per CPU).
If no more tracing is to be done, this option allows you to shrink the
ring buffer down to free up available memory.
trace-cmd reset -b 1
