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,
to indicate to which event type the field list applies.
e.g., -f sw:comm,tid,time,ip,sym and -f trace:time,cpu,trace
