Service Mesh - Graph

🕓 10 minutes

What you’ll learn#

  • How to find dependencies between your applications and their components inside the specific environment.
  • How to investigate the component statistics such as traffic, inbound/outbound metrics for the node or edge, and many more.

Prerequisites#

Steps#

  1. Find the "Service Mesh" section in the sidebar menu and choose the "Graph" option.
    • There you can see a graph that represents the application components that are contained in your environment. The graph also shows how these components are related to each other.
      • Click on a node to see its summary and emphasize its end-to-end paths.
      • Right-click a node or an edge to see the contextual menu with links to the details, traffic and inbound/outbound metrics for the node or edge.
