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.

OpenTelemetry in 2023
Prometheus text exposition format is de-facto standard used in monitoring. It would be great building an official observability standard on top it. This format is much easier to debug and understand than OpenTelemetry for metrics. It is also more efficient, e.g. it requires less network bandwidth and less CPU for transfer than Otel for metrics.

Kubernetes prometheus metrics for running pods and nodes?
I've set up prometheus to monitor kubernetes metrics by following the prometheus documentation.

Minimal, allocation-free OpenMetrics implementation for no-std/embedded Rust
It was added back to Prometheus.

What is promeetheus monitoring?
Exporters are third-party tools that send metrics to the Prometheus server. When Prometheus cannot access metrics, it uses exporters. These exporters export metrics from systems and send the metrics to the Prometheus server. There are official and non-official exporters in Prometheus' GitHub organization.

Energy monitor exporter?
Now I'm looking for another energy monitor and I'm really struggling to find one! https://github.com/prometheus/docs/blob/main/content/docs/instrumenting/exporters.md

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.
