The modeling method that you select depends on your environment and the types of devices that you
want to model and monitor.
By default the system remodels each known device every 720 minutes (12 hours).
The following figure shows how the zenmodeler daemon fits into the
modeling devices portion of the Resource Manager architecture. Note that MariaDB replaced
ZenDS (MySQL) in version 5.x and later and stores the object database (ZODB).
