Dashboard

The Dashboard tab displays charts for CPU load, memory usage, pod capacity, pod statuses, and container restarts. The charts are available for both master and worker nodes.

CPU Core Load

• Capacity: The total number of CPU cores on the node. Measured in cores or millicores.
• Allocatable: The number of CPU cores available for scheduling applications on the node.
• Resource Limit: The total CPU limit set for pods. This indicates the maximum CPU usage allowed for all pods on the node.
• Resource Request: The total amount of CPU requested by all pods on the node.

Memory

• Capacity: The total amount of memory on the node.
• Allocatable: The amount of memory available for scheduling applications.
• Resource Limit: The total memory usage limit set for all pods on the node.
• Resource Request: The total amount of memory requested by all pods.

Pods Capacity

• Allocatable: The number of additional pods that can still be scheduled on the node.
• Requested: The number of pods currently scheduled on the node.

Pods Status

• Running: The pod has been successfully deployed and is running. All containers within the pod are up and running.
• Failed: An error occurred during the execution of one or more containers in the pod. For example, a container exited with a non-zero status code or failed to access required resources.
• Pending: The pod has not started yet because Kubernetes is still scheduling it to a node and has not yet allocated the necessary resources (e.g., node space, networking, or image pulling). To find out the reason, run the command:

kubectl describe node <node_name>

• Unknown: Kubernetes cannot determine the current status of the pod, possibly due to lost connection with the node where the pod was running. This may indicate connectivity issues or system failures.
• Succeeded: All containers in the pod have successfully completed their work. This status typically applies to pods that are designed for one-time execution (e.g., a Job).
