You should periodically monitor the DSfW domain controller for the following:
sysvolsync
Gposync
Time synchronization
eDirectory health
Syslog for critical errors from all DSfW services
KDC log
Samba and winbind logs
Perform xadcntrl validate to ensure that all DSfW services are healthy. Any unexpected errors can lead to domain controller malfunctioning or unnecessary load on domain controllers if not attended to. For more information, see Logging
. For information on eDirectory performance tuning, see TID 3178089.
