Discovery Architecture
A critical part of IT monitoring is creating and maintaining an accurate list of the devices in your IT environment. Finding and listing all addressable devices and computers within a managed IT environment is the job of automated
discovery
.
Once the Unified Management Portal (UMP) is installed, the Discovery Wizard starts automatically and prompts you to configure and run discovery. The wizard allows you to specify authentication credentials and define IP address ranges to scan. Discovery finds virtually all connected resources on the network and provides detailed information about device type, configuration, and asset/inventory data. By using ICMP, ARP, DNS, SNMP (v1, v2, and v3), WMI, SSH, and NetBIOS, discovery finds a wide range of devices and device information.
The list of devices, referred to as your
Inventory
, can be augmented by XML file-based device import. When multiple discovery records correspond to a single device, device correlation and reconciliation is performed to ensure that the device is only listed once.
To maintain current inventory, re-run discovery through the wizard at any time, modifying the credentials and scopes as needed. You can schedule discovery to run on regular intervals.
