2V0-71.23 Question 303
Select 3As a Tanzu Kubernetes administrator, you are tasked with monitoring the performance and health of an application running in a Kubernetes cluster. You decide to use VMware Aria Operations for Applications (formerly Tanzu Observability) to achieve this. Which actions should you take to set up effective observability for your application and ensure proper insights from the platform?
- A
Install and configure the Wavefront Collector for Kubernetes in the cluster to collect metrics.
- B
Enable application-level tracing by instrumenting the application code with the Wavefront SDK or libraries.
- C
Configure role-based access control (RBAC) policies in Kubernetes to restrict access to the Aria Operations interface.
- D
Set up dashboards and alerts in Aria Operations for Applications to monitor key performance indicators (KPIs).
- E
Enable Istio service mesh for the cluster to automatically integrate with Aria Operations for Applications.
Show answer and explanation
Correct answers: A, B, D
Explanation
To effectively leverage VMware Aria Operations for Applications, you need to ensure that metrics and traces are collected from Kubernetes and the application. This involves setting up the Wavefront Collector, instrumenting the application code for tracing, and configuring dashboards and alerts to monitor performance. While other options, such as RBAC policies or Istio service mesh, may enhance security or provide additional telemetry, they are not required for basic observability setup in this context.
- A. Correct.
Installing and configuring the Wavefront Collector for Kubernetes is essential to collect resource usage metrics from the cluster and send them to Aria Operations for Applications for analysis.
- B. Correct.
Application-level tracing allows for detailed insights into application performance and troubleshooting, and this requires instrumenting the application code with the appropriate Wavefront SDK or libraries.
- C. Incorrect.
While configuring RBAC policies is a good practice for securing Kubernetes clusters, it is not directly related to setting up observability in Aria Operations for Applications.
- D. Correct.
Dashboards and alerts are critical components of observability. They enable you to visualize metrics, monitor KPIs, and respond to anomalies or performance issues.
- E. Incorrect.
Enabling Istio service mesh is not mandatory for using Aria Operations for Applications. While Istio can provide additional telemetry data, it is not a necessary step for integrating Aria Operations for Applications.
