VPLEX monitor enable

Might happen that not all default monitors we use providing perfomance data.
To check it and enable use this procedure (all below monitors for each director must be running):
  1. Check monitor status under admin account:
    VPlexcli:/> ll /monitoring/directors/*/monitors/                                                                                                                                                                                            
      /monitoring/directors/director-1-1-A/monitors: 
      Name                                                            Ownership  Collecting  Period  Average  Idle   Bucket  Bucket  Bucket  Bucket
      --------------------------------------------------------------  ---------  Data        ------  Period   For    Min     Max     Width   Count
      --------------------------------------------------------------  ---------  ----------  ------  -------  -----  ------  ------  ------  ------
      director-1-1-A_PERPETUAL_vplex_sys_perf_mon_v19                 true       true        5s      4.97s    2s     -       -       -       64
      director-1-1-A_VIRTUAL_VOLUMES_PERPETUAL_MONITOR                true       true        1min    1min     33s    -       -       -       64
    
      /monitoring/directors/director-1-1-B/monitors: 
      Name                                              Ownership  Collecting  Period  Average  Idle  Bucket  Bucket  Bucket  Bucket
      ------------------------------------------------  ---------  Data        ------  Period   For   Min     Max     Width   Count
      ------------------------------------------------  ---------  ----------  ------  -------  ----  ------  ------  ------  ------
      director-1-1-B_PERPETUAL_vplex_sys_perf_mon_v19   true       true        5s      5.05s    4s    -       -       -       64
      director-1-1-B_VIRTUAL_VOLUMES_PERPETUAL_MONITOR  true       true        1min    60s      33s   -       -       -       64
      ...
    
  2. Delete monitors which are not collecting data
    VPlexcli:/> monitor destroy <monitor name>
    
  3. Restart CLI from server management (not from vplexcli):
    sudo /etc/init.d/VPlexManagementConsole restart
