AlmaLinux 9 / network-scripts?
In that case, it may be helpful to have a reliability "spin" sinilar how there are AlmaLinux Live Media images that allow trying an AlmaLinux desktop without installing. That is not an option on the other EL8 systems despite AlmaLinux also offering 1:1 compatibility. A reliability spin might include other reliability-focused components such as monitoring-plugins and check_systemd

Linux is dead, long-live Docker monoculture
Fast forward 12 years and I have Icinga2 collectors in each datacenter using check_by_ssh to run check_systemd, all front-ended by Thruk. The TIG stack is something on my list of things to look into at some point, but with Dynatrace available to do all the fancy application monitoring, there's no rush.

Anyone using LibreNMS in production?
For alerting for Linux systems, I use Icinga with check_ssh and check_systemd (caveat: distributed primarily on PyPI) with Thruk as the single pane of glass front-end to per-datacenter installations of Icinga.

If you wanted to see exactly how a system was performing when a load threshold was reached, how would you do it?
check_systemd is nice to alert based on failed systemd units - https://github.com/Josef-Friedrich/check_systemd but it requires python3 to install, so there is a bit more to install onto a system.
