node_exporter VS node-exporter-textfile-collector-scripts

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.

For anyone still wondering, the best way I found was to use btrfs_stats.py from this repo and checking when errors are over 0.

Here are some examples https://github.com/prometheus-community/node-exporter-textfile-collector-scripts

node_exporter apt.sh collector

Hi. I use this python script and used this dashboard as template.

That's right.. The smartmon.py doesn't support NVMe SSDs originally so I make it compatible with my SAMSUNG PM983 and very likely it won't work on other SSDs... nvme_metrics.sh seems like a good one to use. Ahh, I didn't notice this.
