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.

AWS EC2 Auto Scaling, Target Tracking Policies and Prometheus Exporters
Pulumi IaC will help us bring up our infrastructure on the AWS Cloud. Check out pulumi.com if you still need to become familiar with it. You can deploy this demo stack using the Pulumi button below.

Terraform - How do you handle secrets?
There are other infrastructure as code tools that take secrets seriously. Pulumi encrypts all values in state and you can even bring your own key from your cloud provider

Observability Mythbusters: Yes, Observability-Landscape-as-Code is a Thing
*Codifying the deployment of the OTel Collector *(to Nomad, Kubernetes, or a VM) using tools such as Terraform, Pulumi, or Ansible. The Collector funnels your OTel data to your Observability back-end. ✅

Interesting tools?

My "infrastructure as code" tool to manage production-grade clusters
it takes too much time, terraform configs are not easy to use also. Pulumi is much better to maintenance. Cloudy is good enough for launching a production-ready cluster in 5-10 minutes. It could be an alternative to kops
-
We're building an open-source tool to deploy infrastructure in multiple clouds
Just wanted to mention a Terraform alternative I really like, especially cause it's infrastructure as code (IaC) http://pulumi.com/, though I'm not sure about their approach on multi cloud, haven't used it in quite a while
-
Deploying Kubernetes Clusters in Increasingly absurd languages
That is the entire point of Pulumi, you should give it a try

Best way to monitor disk space, RAM in remote servers and get alerts when full?
The Prometheus node_exporter can provide this information, doesn't require root. You could run it as a systemd user unit if you don't have root.

Best Course/Learning Path for mastering Prometheus and Grafana
I personally find it best to learn through experimentation. Start with reading a bit about Prometheus and Grafana through their docs, and then familiarise yourself with setting up a local Prometheus + Grafana instance either locally or with docker using docker-compose, along with something to generate /metrics endpoint for Prometheus to scrape from such as a custom Prometheus exporter in Python or using Node Exporter.
-
Linux Traffic Monitoring
Your best bet might be to fork node_exporter to get you more verbose socket stats: https://github.com/prometheus/node_exporter/blob/master/collector/sockstat_linux.go
-
Tool to monitor disk space
I use Grafana + Prometheus + Node Exporter.
- Is there a dashboard of sorts that can keep track of my linux-based computers and VMs to that I can easily see if any of them have updates or are running low on storage and et cetera?
-
Would SNMP present less of a load than SSH to get interface metrics from older cisco 3K series switches?
Crazy idea, can't NX devices run Docker? I wonder if the node_exporter would work.

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.
-
How to log system usage: RAM, CPU, over a long time to detect which component is slowing down?
You may setup node exporter and collect metrics with prometheus for example. Its not quite "simple" way, but still you may find it useful.
