TRACE-CMD-STREAM(1) TRACE-CMD-STREAM(1)
trace-cmd-stream - stream a trace to stdout as it is happening
trace-cmd stream [OPTIONS] [command]
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.
These are the same as trace-cmd-record(1), except that it does not take
the *-o* option.
