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>".
