Checkmk special agent for monitoring Hetzner Storage Boxes via the Hetzner Console API. Tracks storage/snapshot/subaccount usage, access settings (Samba/SSH/WebDAV/ZFS), delete protection, and snapshot plan status, with configurable thresholds. Fork of 47k/checkmk-hetzner-storagebox — fixes Checkmk 2.5 compatibility (the original's rulesets relied on a private GUI API removed in 2.5).
