NAME

6       trace-cmd-stream - stream a trace to stdout as it is happening
7

SYNOPSIS

9       trace-cmd stream [OPTIONS] [command]
10

DESCRIPTION

12       The trace-cmd(1) stream will start tracing just like
13       trace-cmd-record(1), except it will not record to a file and instead it
14       will read the binary buffer as it is happening, convert it to a human
15       readable format and write it to stdout.
16
17       This is basically the same as trace-cmd-start(1) and then doing a
18       trace-cmd-show(1) with the -p option. trace-cmd-stream is not as
19       efficient as reading from the pipe file as most of the stream work is
20       done in userspace. This is useful if it is needed to do the work mostly
21       in userspace instead of the kernel, and stream also helps to debug
22       trace-cmd-profile(1) which uses the stream code to perform the live
23       data analysis for the profile.
24

OPTIONS

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