The purpose of setting ENABLE_AUDIT_LOGGING=true during a cluster deployment is to log metadata about all requests made to the Kubernetes API server. This enables auditing of the cluster activities and helps with security and compliance. The audit logs are stored in /var/log/kubernetes/audit.log on the control plane node and can be accessed by the cluster administrator. The audit logs are generated based on an audit policy file that defines what events should be recorded and what data they should include12

VMware Aria Operations for Applications (formerly known as Tanzu Observability) is a unified observability platform that provides full-stack visibility using metrics, traces, and logs across distributed applications, application services, container services, and multi-cloud environments. Some of the capabilities of VMware Aria Operations for Applications are:

• Create alerts: Users can monitor for certain behaviors and get smart notifications based on query conditions. Users can create alerts independently or directly from charts, and use advanced and accurate alerting powered by AI/analytics and query language1.
• Create charts and dashboards: Users can visualize their data based on query results in various chart types (such as line plot, point plot, table, pie chart, etc.) and organize them in dashboards. Users can also interact with charts and dashboards in real time, such as zoom in, zoom out, change the time window, change the focus, and so on1.
• Create queries: Users can use the Wavefront Query Language (WQL) to extract the information they need from their data. Users can use the Chart Builder for easy query creation or the Query Editor for advanced query editing. Users can also use functions, operators, variables, macros, and expressions to manipulate their data1.

The control plane nodes are the nodes that run the Kubernetes control plane components, such as the API server, the scheduler, the controller manager, and etcd. The control plane nodes are responsible for managing the cluster state and orchestrating workload operations. The possible counts of control plane nodes in a Tanzu Kubernetes Grid workload cluster are 1 or 3. The control plane must have an odd number of nodes to ensure quorum and high availability. A single control plane node is suitable for development or testing purposes, while three control plane nodes are recommended for production clusters23.

To register the vSphere management cluster in VMware Tanzu Mission Control, an administrator can use either the web console or the CLI of VMware Tanzu Mission Control. The web console provides a graphical user interface to perform the registration, while the CLI provides a command-line interface to run a script that automates the registration process. Both methods require the administrator to have access to the vSphere management cluster and to provide some information such as the cluster name, context, and namespace. The registration process creates a service account and a secret in the vSphere management cluster, and generates a kubeconfig file that is used by VMware Tanzu Mission Control to connect to the cluster.
