Имя (Name)

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


Синопсис (Synopsis)

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


Описание (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.


Параметры (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>".
