Modeling is performed using the “ZenModeler” daemon. ZenModeler iterates over the list of devices in the system and attempts to auto-discover the sub-components of each device. This includes network interfaces, file systems, processes, and IP services (as well as others). By default, the system is setup to perform complete remodeling every 6 hours. This may be too often for large deployments. Often this process is run only once per day from a cron job.
