NAME

6       trace-cmd-reset - turn off all Ftrace tracing to bring back full
7       performance
8

SYNOPSIS

10       trace-cmd reset [OPTIONS]
11

DESCRIPTION

13       The trace-cmd(1) reset command turns off all tracing of Ftrace. This
14       will bring back the performance of the system before tracing was
15       enabled. This is necessary since trace-cmd-record(1), trace-cmd-stop(1)
16       and trace-cmd-extract(1) do not disable the tracer, event after the
17       data has been pulled from the buffers. The rational is that the user
18       may want to manually enable the tracer with the Ftrace pseudo file
19       system, or examine other parts of Ftrace to see what trace-cmd did.
20       After the reset command happens, the data in the ring buffer, and the
21       options that were used are all lost.
22

OPTIONS

24       -b buffer_size
25           When the kernel boots, the Ftrace ring buffer is of a minimal size
26           (3 pages per CPU). The first time the tracer is used, the ring
27           buffer size expands to what it was set for (default 1.4 Megs per
28           CPU).
29
30               If no more tracing is to be done, this option allows you to shrink the
31               ring buffer down to free up available memory.
