This topic provides steps to monitor the VMware Telco Cloud Service Assurance for high availability in a VM-based deployment.

Procedure

  1. Discover all the VMs that are part of the VMware Telco Cloud Service Assurance deployment (including the worker nodes, control plane nodes, and deployer VM).
  2. Run the following command to get the VMs from the Kubernetes cluster. 
    kubectl get node -o wide|awk -F" " '{print$6}'|grep -iv INTERNAL-IP
  3. Discover all the VMs/node IPs from the output of the step2 command along with the deployer host as ICMP Mode of discovery in the IP server through the seed file. The VM/node IPs must be updated in the following format in the text file to discover it in IP server. 
    NAMEORIP=<IP1>       SEEDNAME=<IP1>    ACCESSMODE=ICMPONLY
NAMEORIP=<IP2>       SEEDNAME=<IP2>    ACCESSMODE=ICMPONLY
    Note: For discovering the seed file in VMware Telco Cloud Service Assurance IP Manager, see ( add link).
  4. Whenever any VM goes down, you will get the alerts from the VMware Telco Cloud Service Assurance Domain Managers as Host Down, and you must make it Host Up.
