Hi all, I know most of you run servers on nixos, so I would like your opinion on monitoring/guarding system performance and health.
I've used monit in the past to monitor certain processes, which is quite nice, but I think nowadays systemd is capable of setting the same kinds of limits, and since it uses cgroups this will be even more thorough as it catches forked children too. But as I don't fully trust the performance of the cloud hosting I'm using, I would like to gain some insights into more generic stats as well. Things like long io response times that cause dbs to hang might be nice to know about. Also anomalies like tcp queue overflows (indicating synfloods) and stuff like that might be nice to find. Tools like sysstat/sar come to mind, but as these have been around for eons, there might be more modern alternatives that I don't know about yet. What do you use and why?
