Hello Radhakrishnan,
Thank you for posting us. Yes, the cluster agent will monitor your entire cluster and provide you the all the important metrics.
The Cluster Agent collects metrics and metadata for the entire cluster, including every node and namespace down to the container level. When you instrument applications with AppDynamics APM Agents, the Cluster Agent allows you to view both Kubernetes and APM metrics for those pods (if both the Cluster Agent and the APM Agents are reporting the data to the same account the Controller).
You can use Cluster Agent to:
Gain visibility into key Kubernetes metrics and events, and detect uptime and availability issues
Diagnose issues that may prevent uptime or scalability issues, such as:
Pod failures and restarts
Node starvation
Pod eviction threats and pod quota violations
Image and storage failures
Pending or stuck pods.
Bad endpoints: detects broken links between pods and application components
Service endpoints in a failed state
Missing dependencies (Services, configMaps, Secrets)
Track resource usage of pods relative to the declared requests and limits
Please find the document link where you can see detailed metrics that would collected by the cluster agent. https://docs.appdynamics.com/appd/23.x/latest/en/infrastructure-visibility/monitor-kubernetes-with-the-cluster-agent/use-the-cluster-agent/cluster-metrics

Please let us know if you would like to set up a call and learn the basic information regarding the agent. We have a CAC option where customers can have a call with our consultants and learn more about it.
