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),
       trace-cmd-list(1), trace-cmd-listen(1)
