Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- Do we have any Prometheus metric to get the kubernetes cluster-level CPU/Memory requests/limits?

Why is the Prometheus metric 'kube_pod_completion_time' returning empty query results?
https://github.com/kubernetes/kube-state-metrics/blob/main/docs/pod-metrics.md According to this github repo completion is responsible of termination date if I correctly understood .

Prometheus node exporter and cadvisor to send metrics to central prometheus cluster
Those are entirely different types of data. You can get that from something like kube-state-metrics

Scaling kube-state-metrics in large cluster
I've never had a cluster of that size, so take it with a grain of salt - but maybe you could try purpose-based sharding? KSM has allowlist and denylist config flags, for configuring which metrics it exposes https://github.com/kubernetes/kube-state-metrics/blob/main/docs/cli-arguments.md

Questions about Kubernetes
Kubernetes itself will not notify you, the way I've seen people do this, is to use something like kube-state-metrics or node_exporter, export that to Prometheus (or preferrably VictoriaMetrics because Prometheus is terrible IMO), and then setup alarms on that with alertmanager or equivalent, or just look at dashboards regularly with Grafana. Realistically I recommend only setting alerts on disk usage and application/database latency. CPU and memory utilization isn't a great metric to alert on a lot of the time.

EKS scalability best practices
Another tip that you could consider spelling out a little more, is to monitor the number of resources created by Kind. This is somewhat mentioned for jobs and services, but any Kind of which thousands of resources are created will put stress on the control-plane. The total number of resources per namespace/cluster can be monitored with kube-state-metrics. KSM does not emit metrics of resources created from CRDs. These metrics can be implemented with KSM's custom resource state metrics: https://github.com/kubernetes/kube-state-metrics/blob/main/docs/customresourcestate-metrics.md

We then have various other Metrics called Kubernetes Workload Metrics. These are the dashboards with names that start with “Kubernetes / Compute Resources / Workload”. These dashboards are specific to the services you are running. They take into account the Kubernetes Workloads in your various namespaces, using kube-state-metrics. For a closer look, check out otel_demo_app_k8s_dashboard.tf.

Kubernetes Costs: Effective Cost Optimization Strategies To Reduce Your k8s Bill
The first step to optimizing costs is gaining visibility into your costs using tools. Kubernetes provides a Metrics Server and kube-state-metrics that can give you the overall picture of resource utilization by your cluster. There are more tools that provide more granular breakdowns and provide dashboards with business metrics, infra cost, and alerting functionalities. Here are some strategies to optimize your resource utilization and cloud bills on k8s.

Jenkins Agents On Kubernetes
default is where any actions which require a namespace will go into if one is not explicitly defined in a default setup (tools such as kubens can alter this behavior). In the context of Jenkins, namespaces are a useful way to allow isolation of individual Jenkins instances that want to utilize the same Kubernetes cluster. Creation of a namespace is a simple option to kubectl:

[ANN] Kele: Snappy Kubernetes cluster management in Emacs
For a peek at what's currently possible, visit the documentation site, in particular the Usage section. For this initial release, it has feature parity with kubectx and kubens and that's about it, but there's lots of room for growth.

What are some alternatives?
cadvisor - Analyzes resource usage and performance characteristics of running containers.
fzf-tab - Replace zsh's default completion selection menu with fzf!
metrics-server - Scalable and efficient source of container resource metrics for Kubernetes built-in autoscaling pipelines.
kubie - A more powerful alternative to kubectx and kubens
php-fpm_exporter - A prometheus exporter for PHP-FPM.
kubeswitch - The kubectx for operators.
k3s - Lightweight Kubernetes
kubecm - Manage your kubeconfig more easily.
kubespray - Deploy a Production Ready Kubernetes Cluster
kubectl-neat - Clean up Kubernetes yaml and json output to make it readable
