  [root@five ~]# perf test -v daemon
  76: daemon operations                                               :
  --- start ---
  test child forked, pid 792143
  test daemon list
  test daemon reconfig
  test daemon stop
  test daemon signal
  signal 12 sent to session 'test [792415]'
  signal 12 sent to session 'test [792415]'
  test daemon ping
  test child finished with 0
