They always point at the network, but we know:

I found graylog and the likes nice but as you said heavy on resources. I now have a central rsyslog server (on debian 12) that first does some filtering of log lines I don’t care about and then stores log in postgress. Grafana lives on that same host and I’m very happy with it. It performs quite well with just a fraction of resources graylog had as bare minimum. (The server has 4 sockets and 8Gb mem, storage to SSD while 4 firewalls, 3 switches, 4 AP’s and 20 servers logging to it) In the proxmox console I see 2Gb mem is used and the cpu is bored (<5%)

My suggestion, try variouse live distro’s from an USB. Alternatively install debian from it’s ISO and select ALL desktop environments. Then on login you can select which on to use for the current session. Once you made your choice you can do use tasksel to remove the others (although I’d do a re-install with just the one I want)
