NAME         top

       trace-cmd-start - start the Ftrace Linux kernel tracer without

SYNOPSIS         top

       trace-cmd start [OPTIONS]

DESCRIPTION         top

       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

OPTIONS         top

       The options are the same as trace-cmd-record(1), except that it does
       not take options specific to recording (-s, -o, -N, and -t).

           This option is only available for trace-cmd start. It tells
           trace-cmd to not wait for the process to finish before returning.
           With this option, trace-cmd start will return right after it
           forks the process on the command line. This option only has an
           effect if trace-cmd start also executes a command.
