It uses the function tracer and call stacks that it +finds to try to put together a call graph of the events. + +OPTIONS +------- +*-i* 'input-file':: + By default, trace-cmd hist will read the file 'trace.dat'. But the *-i* + option open up the given 'input-file' instead. Note, the input file may + also be specified as the last item on the command line. + +*-P*:: + To compact all events and show the call graphs by ignoring tasks + and different PIDs, add the *-P* to do so. Instead of showing the + task name, it will group all chains together and show "<all pids>". + +SEE ALSO +-------- +trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), +trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1), +trace-cmd-split(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) 2010 Red Hat, Inc.
