Sources Column Details in GAV

The assets are discovered from the following asset inventory sources, and then they are brought into the Global AssetView (GAV) inventory:

API Active Directory Appliance Azure
BMC Helix CAPS CMDB Cloud Agent
IP Scanner Malware Domain Mobility Scanner OCA
OCI Passive Sensor ServiceNow VMWare vSphere

Note: You can run the inventory:(source: QQL from the Inventory > Assets tab and find the assets with the specified inventory source.

When you click the Inventory > Assets tab, you can see asset source details in the Sources column. You can see different sources from where the asset was collected. For a particular source, you can hover on the icon to see the first found and last seen date. Aggregate first found and last seen dates for all sources are displayed under the list of icons in the local timezone. We also display the aggregate UTC time of first found and last seen dates for all assets on hovering over the (i) icon. Refer to the screenshots below. 

Note: As shown in the following screen capture, you can see a specific icon, Third Party Vuln Import, for the third-party vuln imported asset in the Sources column. When you hover over that icon, you can see the first found and last seen details of that asset in the tooltip.
