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>".
