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?
I'd suggest looking at the queries used by the kubernetes mixin dashboards for inspiration.
-
How do you set up Grafana alert for your cluster? Which mixins library?
Came across this lib, but realized the last update was 4 years ago.
-
I need to create an alerting setup for kubernetes nodes cpu utilisation. Can someone give some alerting queries to set it up?
Take a look at the kubernetes mixins to get an idea and/or starting point

How to Monitor your k8s Persistent Volume Usage
The last step is to use the Mixin dashboard to visualize the usage of PV, you can get it from here

How to silence Prometheus Alertmanager using config files?
It's working good so far, except for the annoying CPUThrottlingHigh alert that is firing for many pods (including the own Prometheus' config-reloaders containers). This alert is currently under discussion, and I want to silence its notifications for now.

The Dhall Configuration Language
I think it might still have issues figuring out that it needs to apply CRDs first: https://github.com/grafana/tanka/issues/246 Besides that, I found it super-handy for deploying https://github.com/prometheus-operator/prometheus-operator and https://github.com/kubernetes-monitoring/kubernetes-mixin
- Kubernetes Monitoring
-
Prometheus Definitive Guide Part III - Prometheus Operator
These all standard dashboards are basically generated from the kubernetes-mixin project.

What is the ultimate list of alerts when monitoring an on-premise k8s cluster?
I would suggest looking at the Kubernetes Mixin: https://github.com/kubernetes-monitoring/kubernetes-mixin, it has both alerts and Grafana dashboards.

The Dhall Configuration Language
> jsonnet seemed like a great idea to me, but I've experienced extremely low performance.
Although each implementation of jsonnet has some quirks, take a look at (scala-based) sjsonnet^1 or go-jsonnet^2 for improved performance. We use go-jsonnet because of some issues we had with the scala version - but it does seem to be the fastest by a large margin.
There's also a Rust version^3 that claims to be the fastest yet^4, but I haven't experimented with it at all.

Template engines / expression languages for YAML?
Check out Jsonnet, specifically this Scala implementation. I'm currently generating a lot of OpenAPI YAML using it, and couldn't be happier.
What are some alternatives?
