Monitor TrueNAS · Proxmox · ZFS with an agent that reports to one console.

TrueNAS, Proxmox, any Linux or FreeBSD host with zpool. Pools as volumes with health. A degraded pool is a critical alert; a full pool is caught even when df says otherwise. BE AI investigates when something fails; a person approves the fix.

install

One line, from the company's install page.

Run in a root shell (TrueNAS SCALE and Proxmox are Linux; TrueNAS CORE uses the FreeBSD line). It fetches the signed binary, verifies the checksum, installs the service and connects. Run it again any time; it never overwrites the machine's identity.

curl -fsSL https://hub.[yourdomain]/install/inst_…/linux.sh | sudo bash

Outbound 443 to the hub only. No inbound rule, no VPN, no SNMP community.
