VMware Telco Cloud Service Assurance release brings features and enhancements across platform and virtual infrastructure management areas. This release introduces new functionalities like the deployment and rollback of patch and new usecase support for Cell Site Groups.

5G Core and vRAN Assurance

  • Support for Cell Site Group discovery and monitoring: VMware Telco Cloud Service Assurance supports the discovery and monitoring of the Cell Site Groups to support the day 0 launch steps in VMware Telco Cloud Automation.

  • Support for Cell Site Group vRAN connectivity maps, topology browser, new events, and RCA.

Platform Modernization

VMware Telco Cloud Service Assurance now provides support for deployment and rollback of patch. For more information, see Patch Deployment and Rollback in VMware Telco Cloud Service Assurance Deployment Guide.

Fixed Issues

  • Apiservice must not allow anonymous user to access cluster resource.

    Apiservice was creating cluster-rolebindings with anonymous user access which could be potential security issue, therefore cluster-rolebindings has been removed.

  • Kafka Collector deserialisation issue.

    Kafka Collector does not process messages when '/' is contained any of the values in the incoming JSON messages.

  • VMware Smart Assurance Integration fails in the VMware Telco Cloud Service Assurance when running on AKS 1.22.x platform. Where "x" version is 11 or higher.

    In VMware Telco Cloud Service Assurance, Kubernetes Python SDK was used. When Kubernetes Python SDK get nodes API invoked on the Azure resulted in failure with error Invalid value for `names`, must be `None`.

    This has been fixed by using the REST API to list nodes instead of using Kubernetes Python SDK.

Known Issues

  • Cell Site instances are not available in Topology Browser and Maps of VMware Telco Cloud Service Assurance UI.

    Follow the procedure to get the Cell Site instances.

    1. Login to jobmanager pod.

    kubectl exec -it flink-jobmanager-0 bash

    2. Run the following command:

    cd /opt/flink/data/jars/flink-web-upload

    3. Delete the following jar:


    4. Check the logs of the Topology pod:

    Kubectl get pods | grep topology
    kubectl logs -f <<topologypod_name>>

    From logs , get the respective job ids for the jobs named “Topology-Cleanup” and “Topology-Processor”.

    For example, "jid": "1ffeb29940ca9c06d803fbf18fd5a416",”

    5. Login to the Topology pod.

    kubectl exec -it <<topologypod_name>> bash

    6. Run the following commands:

    curl -X PATCH http://flink-jobmanager:8081/jobs/<<Topology-Cleanup job d>>?mode=cancelcurl -X PATCH http://flink-jobmanager:8081/jobs/<<Topology-Processor job d>>?mode=cancel
  • Grafana service Reconcile is failing post patch uninstallation.

    VMware Telco Cloud Service Assurance Patch uninstallation fails with the following error:

    + helm upgrade --wait --install --timeout 1800s tcsa /root/tcx-deployer/product-helm-charts/tcsa -f /root/tcx-deployer/product-helm-charts/tcsa/values.yaml -f /root/tcx-deployer/product-helm-charts/tcsa/values-tkg.yaml -f /root/tcx-deployer/product-helm-charts/tcsa/values-tkg-50k.yaml -f /root/tcx-deployer/product-helm-charts/tcsa/values-imgpkg-overrides.yaml --set registryRootUrl=tcotkgregistry.azurecr.io/tcops25ksanity/tcx --set ingressHostname.product= --set footprint=50k --set statusChecker.timeout=1800 --set appSpecs.nginx.helmOverrides.productInfo.footPrint=50k --set asynchronousMode=true --set appDeploymentInterval=2s
    Error: UPGRADE FAILED: post-upgrade hooks failed: timed out waiting for the condition

    Output of kubectl get apps command:

    grafana Reconcile failed: Deploying: Error (see .status.usefulErrorMessage for details) 2m40s 19h

    Delete the tco-grafana-deployer-job using kubectl delete job tco-grafana-deployer-job. This must let the App CR reconciliation pass.

    Reconciliation process takes few mins and the Grafana will be successfully deployed.

  • VMware vRealize Operations and NFV-SOL collectors uses old image post upgrading to 2.0.1 Patch.

    kubectl get deployments | egrep “vmware-vrops|nfv-sol”
    kubectl delete deployment <old-collector-id>

    From the ESM Domain Manager Install (SMARTS_HOME/bin) run the below commands to delete the existing Collector Instance IDs:

    ./dmctl -s <ESMServer> -b <Broker:Port> invoke ICF_PersistentDataSet::TCACollectorInstanceIds clear
    ./dmctl -s <ESMServer> -b <Broker:Port> invoke ICF_PersistentDataSet::CNFCollectorInstanceIds clear
