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.

Need Recommendation: btop like web page for docker
https://github.com/google/cadvisor exports Prometheus metrics, but also offers a simple web-ui for container metrics.

Prometheus JMX Exporter for Java17
For CPU and memory metrics, you can use cAdvisor to collect container level data.

Docker Monitoring Solution?
Perhaps https://github.com/google/cadvisor + prometheus (or influx or whatever else) + grafana?

Building a realtime performance monitoring system with Kafka and Go
We could have used a much more focussed tool like Prometheus or Cadvisor to gather system stats, but that is not the main objective of this article.

Can ChatGPT Debug and Fix your Docker and Kubernetes Issues?
Result: Interestingly, the GitHub Issue that talks about cAdvisor and Docker Desktop for Mac for running cAdvisor is still open and not fixed.

Looking for an open source monitoring solution that will capture specific process info
If you're running things under systemd, you can enable process accounting and use cAdvisor.

Node Exporter
-
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.
What are some alternatives?
kube-state-metrics - Add-on agent to generate and expose cluster-level metrics.
process-exporter - Prometheus exporter that mines /proc to report on selected processes
Netdata - The open-source observability platform everyone needs
Zabbix - Real-time monitoring of IT components and services, such as networks, servers, VMs, applications and the cloud.
ping_exporter - Prometheus exporter for ICMP echo requests using https://github.com/digineo/go-ping
Portainer - Making Docker and Kubernetes management easy.
fortigate_exporter - Prometheus exporter for Fortigate firewalls
prometheus - The Prometheus monitoring system and time series database.
windows_exporter - Prometheus exporter for Windows machines
Healthchecks - Open-source cron job and background task monitoring service, written in Python & Django
