To model devices, Zenoss can use:
SNMP
SSH
WMI
Telnet
The modeling method you select depends on your environment, and on the types of devices you want to model and monitor.
Zenoss employs the zenmodeler daemon to model devices. The zenmodeler daemon iterates over the list of devices in the system and attempts to discover components -- such as network interfaces, file systems, process, and IP services -- of each device.
By default, Zenoss remodels each known device every 720 minutes (12 hours). You can change this interval by editing the value of Modeler Cycle Interval in the collector's configuration.
For larger deployments, modeling frequency may impact performance. In such environments, Zenoss recommends running the modeling process once daily from a cron job.
