This is my first post on the forum so hopefully all will make sense (no pun intended), and someone can help.
I have a NetGate 5100, and the disk usage seems to be really high as the box isn’t doing too much. I can’t see a way of reducing this or seeing where all the space is being taken.
My assumption is that you may have adjusted the logging, here is the usage on my 6100 that is running, Suricata, HAProxy, ACME, Zabbix, 2 OpenVPN, One Wireguard, FreeRadius, & Tailscale.
