From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Netdata is exactly what you're looking for. It's basically an all in one monitoring and and alerting suite that collects and analyzes data, and provides a gorgeous web dashboard for you to view.
You can also manually replicate this using Prometheus, Grafana and other tools, but that requires a much bigger effort to set up.
Edit: There's a public demo instance where you can try everything out: https://frankfurt.netdata.rocks/
Seconding Netdata, I've been using it for years. It's pretty great.
I think they went to 5 nodes max on the free version as of the last patch. That's damn near useless.
Oh that sucks. I haven't used it personally in quite a while, since I switched to the Grafana stack
Is that just for the centralized dashboard portion? I tend to use each instance of it standalone, and primarily for the email alerts.
I believe so. I imagine the next stage of the enshittification will be to force those standalones to register with a portal account.
That would be a truly dark day. I never liked their centralized dashboard functionality, it always seemed cumbersome to me.
I hope that doesn't happen, but I guess if it does, I will really need to find a different monitoring tool.
The five node limit is a dealbreaker for me too. I'm also annoyed the free version doesn't have any real built in options to secure data by default. I followed a TechnoTim tutorial to get the NetData/Prometheus/Grafana stuff setup but it was too limited and required too much manual effort.
