During deployment, few system-level services run automatically on each node (VM). These services ensure that the node might join the VMware Telco Cloud Operations cluster and start all the application services. After deployment, if VMware Telco Cloud Operations does not appear to function, the first step is to verify the logs for these services on the node (control plane node or worker node). For more information, see the VMware Telco Cloud Operations Troubleshooting Guide.
