Key metrics for monitoring Karpenter

Here's a concise summary of the "Understanding Karpenter architecture for Kubernetes autoscaling" article:

Karpenter is an open-source autoscaler for Kubernetes that directly provisions and manages compute capacity (nodes) based on pending Pod requests, bypassing the limitations of traditional cluster autoscalers. Instead of scaling node groups, Karpenter directly launches right-sized instances optimized for workloads, leading to faster scaling and better resource utilization. This architecture allows for significantly improved efficiency and cost savings by eliminating over-provisioning and adapting to diverse workload requirements.
