TRACE-CMD-HIST(1)		[FIXME: manual]		     TRACE-CMD-HIST(1)

NAME
       trace-cmd-hist - show histogram of events in trace.dat file

SYNOPSIS
       trace-cmd hist [OPTIONS][input-file]

DESCRIPTION
       The trace-cmd(1) hist displays a histogram form from the trace.dat
       file. Instead of showing the events as they were ordered, it creates a
       histogram that can be displayed per task or for all tasks where the
       most common events appear first. 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>".
