Enabling Pod Metrics

$podIP: IP address of the pod
$port: listening port

CCI 2.0 supports basic monitoring of pod resources with multiple metrics, such as metrics for CPU, memory, disk, and network. Pods have built-in system agents, which provide pod and container metrics over HTTP by default. The agents are integrated into pods and occupy resources in the pods. You are advised to reserve 30-MB memory.

Basic metrics include those for CPU, memory, disk, and network. For details, see Resource Metrics.
