trace-cmd-start
TRACE-CMD-START(1)TRACE-CMD-START(1)NAME
trace-cmd-start - start the Ftrace Linux kernel tracer without recording
SYNOPSIS
trace-cmd start [OPTIONS]
DESCRIPTION
The trace-cmd(1) start enables all the Ftrace tracing the same way trace-cmd-record(1) does. The difference is that it does not run threads
to create a trace.dat file. This is useful just to enable Ftrace and you are only interested in the trace after some event has occurred and
the trace is stopped. Then the trace can be read straight from the Ftrace pseudo file system or can be extracted with trace-cmd-extract(1).
OPTIONS
The options are the same as trace-cmd-record(1), except that it does not take options specific to recording (-s, -o, -F, -N, and -t).
SEE ALSO trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1),
