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