НАЗВАНИЕ

       trace-cmd-stream - stream a trace to stdout as it is happening

СИНТАКСИС

       trace-cmd stream [OPTIONS] [command]

ОПИСАНИЕ

       The trace-cmd(1) stream will start tracing just like
       trace-cmd-record(1), except it will not record to a file and
       instead it will read the binary buffer as it is happening,
       convert it to a human readable format and write it to stdout.

       This is basically the same as trace-cmd-start(1) and then doing a
       trace-cmd-show(1) with the -p option. trace-cmd-stream is not as
       efficient as reading from the pipe file as most of the stream
       work is done in userspace. This is useful if it is needed to do
       the work mostly in userspace instead of the kernel, and stream
       also helps to debug trace-cmd-profile(1) which uses the stream
       code to perform the live data analysis for the profile.

ПАРАМЕТРЫ

           These are the same as trace-cmd-record(1), except that it does not take
           the *-o* option.
