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.

Prometheus Fundamentals (Lesson-01)
$ wget https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-amd64.tar.gz $ tar -xzvf node_exporter-1.7.0.linux-amd64.tar.gz

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.

Network monitoring suggestions
It is kind of described here:https://github.com/prometheus/snmp_exporter/issues/405
The SNMP exporter can do lookups. Take a look at this documentation.

Does anyone know of a guide for installing snmp_exporter on ASUS router running merlin firmware?
You need to find the OSBs for the router, and add those to the explorer. Take a look at this doc: https://github.com/prometheus/snmp_exporter/blob/main/generator/README.md
-
Loadmaster exporter?
You can fetch this metrics using the SNMP exporter https://github.com/prometheus/snmp_exporter

Real-Time monitoring and alerting software
As a maintainer of the Prometheus SNMP exporter, and the defacto standard implementation of SNMP in Go, I can tell you exactly how convoluted SNMP is at a protocol and specification level.

Self-hosted Netdata alternative? (Windows/Linux clients; server/nodes overview)
Refer to https://github.com/prometheus/snmp_exporter and https://blog.paessler.com/how-to-enable-snmp-on-your-operating-system
-
Observium, SolarWinds NPM or Something else?
For example, you can use unpoller to bring your unifi stuff into the same system as your SNMP data.
-
How to see Temperature data?
SNMP by itself is a rather crude protocol, with values being identified as OID (Object IDs). Those are numerical identifiers. A MIB-File contains the information on how to translate these OIDs into workable data. There is some information on how to feed these files to the exporter located here: https://github.com/prometheus/snmp_exporter/tree/main/generator
