Dependency Graph

You can view the topology of deployed services and resources through the dependency graph. Walrus provides dependency graphs at two levels: environment and service/resource.

Environment Dependency Graph​

The environment dependency graph includes all services and resources in the environment, as well as their relationships and deployment status.

  1. Click Application Management in the left navigation bar to enter the project and environment.
  2. Click the Dependency Graph tab to view the environment dependency graph.

Note: In the dependency graph, sub-nodes that are "implemented" and "inherited" are hidden by default. They can be expanded by clicking on the "Show Sub-resources" icon in the toolbar.

Service/Resource Dependency Graph​

The service/resource dependency graph displays all components under the service or resource, as well as their relationships and deployment status.

  1. Click Application Management in the left navigation bar, enter the project and environment, and go to the service or resource detail page.
  2. Under the Components tab of component information, click the icon on the right to switch to the graph view.

Dependency Graph Node Relations​

The relationships between nodes in the dependency graph can be divided into three categories:

  • Composition: A component relationship, represented by a solid line and a diamond arrow
  • Dependency: Denotes dependency, represented by a dashed line and a V-shaped arrow
  • Realization: Realization or inheritance, represented by a dotted line and a triangular arrow
