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.

[Request for opinion] : CPU limits in the K8s world
Careful assuming system reserved will be present. Last I checked, AWS EKS does not have system reserved resources for the kubelet by default and as a result, pods can starve those for resources (e.g., https://github.com/awslabs/amazon-eks-ami/issues/79). This is of course more important for memory, but could impact CPU as well.

Hands-on lab for studying the EKS, which scenarios I should learn?
I found this document that lists the pod limits per node size. I suspect you will want to consider larger worker nodes or you will very quickly be unable to schedule additional workloads.

EKS: Shoudnt nodes autoscaling group take pods limit into consideration?
No, the new node is added if there are not enough resiurces to start a new pod. So if you have many pods with small resource usage you can hit the pod per node limit, on eks you have a max number of pods depending on the instance type - https://github.com/awslabs/amazon-eks-ami/blob/master/files/eni-max-pods.txt You can incerase that limit : https://docs.aws.amazon.com/eks/latest/userguide/cni-increase-ip-addresses.html

Best managed kubernetes platform
So it manifests itself in this way: your pod is scheduled but remains pending forever. You check the logs and you see that it's complaining that the an IP address. Ultimately, if you check here, you see the maximum number of pods that can be scheduled on any underlying ec2 instance, even if you have remaining IPs in your subnet. I found this to be one of the most poorly understood phenomena in EKS. Even those who claimed to "crack" it and wrote fancy blog posts about it fundamentally got it wrong. AFAIK this document reflects the official AWS guide on how to mitigate this.

Is anyone using Grafana for your network monitoring?
Prometheus is a great way to go, however you need to invest time in writing all the alerts. This was a daunting task for us, because we have too many vendors and device types.. we instead went with zabbix, which is a free open source platform similar to Orion. Quite easy to setup. All the device templates for monitoring alerting are provided by the community. There is a grafana plugin which integrates with Zabbix, so you can build beautiful dashboards in grafana while using the polling and alerting logic in zabbix. You can also use grafana OnCall via a zabbix integration. Phase1: You could move to zabbix. Realize cost savings without investing time. Phase2: learn and work on moving things to Prometheus slowly. edit: added links and some rewording

Ascertaining how much traffic backups generate
Setup Zabbix (https://www.zabbix.com/) and use SNMP (search for a template for your switches, chances are someone has created one) to pull throughput data from the switchport your proxies are connected to. This will graph them for you on a continual basis, you can then setup some triggers (alerts) that will flag over-utilization (say >80Mbps) for you, can generate an email or SMS alert based on that or just see it in the dashboard.

Any good and free tool to test network connection health? (see description for details)
Look at setting up Zabbix (https://www.zabbix.com/) you can then do ping and latency tests to key hosts/endpoints and get packet loss and other variables in a graphical format. Also will allow you to setup monitoring to alert when there are known issues.
