Device Inventory

Device Inventory manages the registration of network devices and monitoring settings. Devices can be automatically discovered using the Auto Discovery feature provided by the manager or manually added as needed. Each registered device can be configured with SNMP based monitoring and Health Check to monitor real time status. This allows integrated management of devices to be monitored in the network management system.
