PROGRAM:
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>".
