MainsailOS VS node_exporter

I used a MainsailOS image from https://github.com/mainsail-crew/MainsailOS/releases the ...orangepi-orangepi_zero2.img.xz image

You need a Raspberry Pi. I would recommend downloading MainsailOS and putting it on the Pi. That has all the things you need pre-installed and you only have to configure it

Here is the mainsail.cfg file

include the code from that mainsail.cfg file in your printer.cfg file(above the "Do not edit below this line" section)

You need to use raspi light "classic" or mainsailos from https://github.com/mainsail-crew/MainsailOS/releases/tag/0.5.0 to insure your raspian is buster and not bullseye.

However MainSailOS is a beautiful Klipper front end project too. https://github.com/mainsail-crew/MainsailOS

Yes it would be the optimal way to setup Octoprint or finished Raspberry Images like FluiddPi or MainsailOS Octoprint is the „official“ base for Klipper though personally I never had a need for Octoprint Plug-ins and use FluiddPi since a year. Klipper has also its subreddit /r/Klippers

$ 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

Node Exporter

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.

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.

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

I use Grafana + Prometheus + Node Exporter.

Crazy idea, can't NX devices run Docker? I wonder if the node_exporter would work.

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.

You may setup node exporter and collect metrics with prometheus for example. Its not quite "simple" way, but still you may find it useful.
