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.😉
Thats basically the way I do it.
pvesh get /cluster/resources --output-format json-pretty | jq --arg k "lxc/$container_id" -r 'map(select(.id == $k))[].name, map(select(.id == $k))[].mem, map(select(.id == $k))[].maxmem, map(select(.id == $k))[].cpu')Example using pvesh in proxmox. The data is available, just have to use it. I also prefer barebone approach.
At last we keep it simple ;)
