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. + +SEE ALSO +-------- +trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), +trace-cmd-stop(1), trace-cmd-reset(1), trace-cmd-split(1), +trace-cmd-list(1), trace-cmd-listen(1) + +AUTHOR +------ +Written by Steven Rostedt, <rostedt@goodmis.org> + +RESOURCES +--------- +https://git.kernel.org/pub/scm/utils/trace-cmd/trace-cmd.git/ + +COPYING +------- +Copyright \(C) 2014 Red Hat, Inc.
