Entity List¶

Go to Unified Catalog > Entity List to view and manage entity assets in the current Workspace, including systems, services, hosts, databases, and more.

Find Entities¶

The page displays entities under the "System" type by default. The left side shows the count for each entity type; click a type name to switch the view.

You can filter by a specific project using the "Project" dropdown in the upper-left corner, or enter a keyword in the search box at the top to perform fuzzy matching across all string-type fields.

Services¶

Go to Unified Catalog > Entity List and select Services in the entity type list on the left to view and manage service assets in the current Workspace.

The service list supports search, project filtering, custom display fields, data export, and viewing, editing, and deleting services.

To manually add a service, click Add in the upper-right corner and select Services as the entity type. For specific field descriptions, see Creating Entity Objects.

Shortcut¶

Click the Settings icon in the left sidebar to quickly access:

• Creating Entity Objects: Enter new asset information

• Managing Entity Types: Jump to the entity type management page to view preset types

List Actions¶

View Modes¶

All entity types, including custom types, support list mode. When System is selected in the left type panel, you can also switch to card mode from the upper-right corner.

List Mode¶

Displays entities of the selected type as a list, making it easy to view entity summaries and expand subordinate entities as needed.

Using the System type as an example, the main list by default includes Type, System Name, Health, Entity Count, System Type, Project, Severity, Team, Custom Tags, and the Operations column. You can sort by Health in ascending or descending order.

View Subordinate Entities¶

All entity types, including systems, other preset types, and custom types, support drill-down in the list to view subordinate entities. You can expand up to three levels to browse entity ownership relationships.

1. Click the expand icon before an entity row to view the subordinate entities belonging to it.
2. If a subordinate entity still has an expand entry, continue expanding to view the next level of subordinate entities.
3. Click the entity name to open Entity Details and view its metadata, relationship topology, and associated observability data.

The subordinate entity list includes Entity Name, Entity Type, Alert Count, Project, Team, Tags, and Last Updated Time. For example, after expanding a system to view its component entities, you can continue expanding entries that have subordinate entities to inspect their ownership structure level by level.

Card Mode¶

Card mode is better suited for quickly reviewing the overall status of multiple systems. Each card focuses on one system and intuitively presents core summaries such as its health, total entity count, number of entities with alerts, and last alert time, without expanding the full entity list, avoiding information overload.

• The upper-left of a card shows the system icon and name, while the upper-right directly shows the health status and operation actions.
• If a system has no alerts, "Last Alert Time" displays as -.
• If health cannot be calculated at the moment, it is marked as "Unknown".

Customize Display¶

The fields in the entity list are dynamically generated from the YAML configuration of the selected type. Click the "Display Fields" button in the upper-right corner to toggle the following fields:

• System Type: classification identifier of the entity
• Project: name of the project it belongs to
• Environment: e.g., production, test, development
• Severity: e.g., critical, normal
• Team: name of the responsible team; click to go to details
• Custom Tags: up to 2 displayed

Export Data¶

Click the "Export" icon to export all entities under the current filter conditions (not limited by pagination) as a CSV file.

View Details¶

Click an entity name in the list to slide out the Details Page from the right, showing complete metadata, relationship topology, and associated observability data.

Quick Actions¶

Click the icon to:

• Edit: modify entity information
• Delete: delete the entity after a second confirmation
