    Network Intelligence Service:Work with SLB topology

    Last Updated:Apr 01, 2024

    A Server Load Balancer (SLB) topology displays the connections between listeners and backend server groups of an SLB instance. You can view the basic information about the network instances in an SLB topology and analyze these instances to check whether traffic is routed as expected.

    Limits

    • Backend server groups must be bound to listeners. If a backend server group is not bound to a listener, the backend server group is not displayed in an SLB topology.

    • Only the resource topologies of Classic Load Balancer (CLB) instances are displayed on the SLB Topology page.

    Resource topology

    1. Log on to the NIS console.

    2. In the left-side navigation pane, choose Network Topology > SLB Topology.

    3. On the SLB Topology page, select CLB from the SLB Type drop-down list, and select a region and an instance ID for which you want to view the SLB topology. Then, click Generate Topology.
