#### Using the Inventory

The Inventory page is the heart of Rumble Network Discovery and the key to understanding what is on your network. The Inventory displays all assets within the Organization and can be sorted, filtered, and exported to obtain specific views of the environment. Data is loaded into the inventory using New Scan and Import actions. The results are analyzed and merged, updating asset information as necessary.

An asset within Rumble is defined as a unique network entity. Assets may have multiple IP addresses and MAC addresses and these addresses may change as the environment is updated. Rumble tracks assets based on several heuristics, including MAC address, IP address, hostnames, and fingerprint results for the operating system and running services.

In most cases, Rumble can accurately follow assets over time in environments using DHCP, even across remote subnets. For external networks, scans that are initiated with fully qualified hostnames will consolidate assets based on the hostname, which allows for consistent asset tracking for cloud-based external systems with dynamic IP addresses.

Within an organization, assets are isolated by site, and each site can have address space that overlaps with other sites. Sorting the Inventory view based on the site column can help in these scenarios, as can filtering the Inventory based on a specific site name.

The search field allows the Inventory to be filtered based on the specified criteria. Please see the Search Query Syntax documentation for specific details.

In addition to viewing assets, the Inventory page provides data export functionality, along with the ability to select assets, and specify the comments field . The Rescan action can be used to selectively rescan specific systems from the inventory, while the Remove Assets and Purge Assets can be used to permanently remove data from the inventory view.
