I use some batch scripts in my proxmox installation. They are in cron.hourly and daily checking for virus and ram/CPU load of my LXC containers. An email is send on condition.
What are your tipps or solution without unnecessary load on disc io or CPU time. Lets keep it simple.
Edit: a lot of great input about possible solutions. In addition TIL “that keep it simple” means a lot of different things to people.😉
Nagios. Core, but i’ve worked with it for years and am kinda masochistic. (Currently tying it into an IDRAC6)
Same here, nagios4 from the debian distro.
I really need to check if it still works. ;)
Nagios FTW!
