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.

Current network throughput from total byte value?
The Telegraf (v1.27.3) Net Input Plugin only reports total numbers - i.e., total bytes received by an interface.

Right way to link containers on host vs custom network.
That's the thing, I do need network_mode: host on telegraf in order to get host network statistics. See here or here

Telegraf Inputs.SMART
After screwing around with it for a while, I was able to get inputs.smart working... but I'm not thrilled with the answer. According to this in order for you to get the SMART data inside a container you need to edit the sudoers file inside the container.

Learnings from integrating JMX based metrics from Java applications into time series databases
I’ve been using the Jolokia agent with telegraf to push JVM metrics into InfluxDB (among other things). I think it can be used with Prometheus too.

Help with reading modbus using telegraf
I have two devices; both are connected to a Raspberry Pi using a USB converter as Slave 1 and 2. I want to get some readings using Telegraf software https://github.com/influxdata/telegraf/tree/release-1.26/plugins/inputs/modbus (happy to try any other linux software), but I'm having trouble (I'm seriously confused to be honest) with byte_order, data_type, and input register addresses.

Telegraf processor plugin.
Yeah i think you can use the grok processor, docs found here: https://github.com/influxdata/telegraf/tree/master/plugins/parsers/grok
