In multi-smarts-topology, the topology explorer is not showing any/new instances available in the configured SAM server.

Steps to troubleshoot the logs:
  1. Verify whether the collector is running by selecting the status column for the Notification collector under Administration > Integrations > Smarts Integrations > Select SAM > Details > Presentation SAM Details > Topology Collectors:
  2. Start the collector multi-smarts-notifs, if it is in the stopped state.
  3. If the Topology explorer is still not updated in the UI, then run the following command on the VMware Telco Cloud Service Assurance control plane node to view the latest log messages from the collector:
    get instance name 
    kubectl get deploy -o=custom-columns="NAME:.metadata.name,SEC:.spec.template.spec.containers[*].env[*].value" | grep <SAM ADDRESS>| grep multi-smarts-topology |cut -f 1 -d ' '
    get pods name 
    kubectl get pods -o wide --show-labels  --selector 'app=collector-manager ,instance_id=<instance name from previous command>'| awk '{print $1}'
    get logs 
    kubectl logs -f <pod name from above command>
