         Comma separated list of fields to print. Options are:
-        comm, tid, pid, time, cpu, event, trace, ip, sym, dso, addr, symoff, srcline.
+        comm, tid, pid, time, cpu, event, trace, ip, sym, dso, addr, symoff, srcline, period.
         Field list can be prepended with the type, trace, sw or hw,

         e.g., -f sw:comm,tid,time,ip,sym  and -f trace:time,cpu,trace
