Procedure

  1. Log in to the VMware Telco Cloud Automation web interface.
  2. Navigate to Infrastructure > CaaS Infrastructure > Cluster Instances.
  3. To view more details, click on the specific management cluster. You can view the details of the cluster and the health of various components associated it.
  4. Details provides the following information:
    • Cluster Type - Management.
    • Cluster Username - name of the cluster.
    • Cluster Template - Template of the management cluster.
    • Kube VIP - Endpoint IP of the cluster.
    • Cluster URL - Kubernetes cluster API URL.
    • vSphere Cluster Name: Name of the selected vSphere cluster.
    • IP Version - Endpoint IP version of the cluster.
  5. (Optional) Airgap Server provides information on if the airgap server is configured.
  6. Components displays kubernetes core services runtime status.
    Status Description
    Healthy The component is working properly.
    Unhealthy The component is not working properly and has some faults.
    Unknown The component is not available.
    Note: When the cluster is under upgrade or creation, the status may show Unknown.
  7. Click the component name to view details.
    • The status of the component.
    • The Pods information includes the pod Name, Created, Ready Containers and Phase.
    • Click the pod name to view the details.
      Note: VMware Telco Cloud Automation obtains the health status directly from Kubernetes and displays that health status on VMware Telco Cloud Automation user interface. Kubernetes maintains the conditions and details.
      • Details: Shows the Namespace, Node name, Creation Timestamp, and IP associated with the Pod.
      • Conditions: Shows the status of Initialized, Ready, Containers Ready, and POD Scheduled conditions.
      • Containers: Shows the Name, State, and Started At time of the container.
  8. Connected Endpoints displays the status of the cluster associated endpoints.
    • Endpoint: The connected endpoint URL.
    • Endpoint Type: The connected Endpoint type. Supported Endpoints types for management cluster are:
      • vCenter Server
      • Airgap Server
    • Status: The connected endpoint status. For details on status, refer to Connected Endpoint.
    • Certificate Expires in: Expiry date of connected endpoint certificate.
    • Health: Monitor operator will automatically monitor the cluster connected endpoints without any user intervention on cluster, probe method default configuration.
    Endpoint Probe Method Probe Interval Probe Timeout Setting Description
    vCenter Thumbprint Check 5m 30s Check if the thumbprint saved in VCenterPrime matches the actual one returned from the vCenter Server.
    Credential Check 1h 30s Check if the credential saved in VCenterPrime's referring secret is valid and can be used to log in to vCenter.
    Airgap Certificate Check 5m 30s Check if the CA certificate in the TcaKubernetesCluster is valid and can be used to verify the certificate from the airgap appliance.
    Readyz Status Check 5m 30s Query the readyz API from the airgap appliance to get the current readyz status report.

    The table below displays the status of endpoint probes from the cluster:

    Status Description
    Healthy Relative probe methods are successful.
    Unhealthy At least one of the relative probe methods is successful.
    Unknown Endpoint has not been monitored yet.
