SDU

StorageDiag Utilities_ formerly Silas Doctor Utilities An advanced, Linux-class diagnostic & recovery workbench — running right on your QNAP NAS. StorageDiag Utilities (SDU) is the local-only edition of the live tools from StorageDiagLV, installed directly on the client — your QNAP NAS — from the sdu.qpkg package. Everything runs on that box and reads its own data: SMART/FARM straight from the live drive, /proc, network interfaces, RAM. This is not a log-dump reader — it is an active workbench. The unprivileged web panel never runs commands itself; it hands operations to a trusted daemon running as root, drawn only from a fixed, allowlisted set of operations (configuration can only disable them, never add). Built for support engineers and admins who need to confirm and act on a live machine. ▲ Note: the live tools hand operations to a root daemon. Use Safe mode and never expose the panel to the public internet without HTTPS, strong credentials and a firewall. The live tools ◆ Pulse — performance & process cockpit CPU/RAM/load meters, a process tree with actions (kill, renice, CPU governor, drop caches) and tabs for network, VMs, databases, logs and a Wireshark-style packet analyzer (recognises SMB, torrents/DHT, SSDP, QNAP discovery; minimap, bookmarks, IP→host resolution). ◆ memhound — RAM tester An original memory tester with memtest86-style patterns plus a fast test. Its principle: never a false positive — a flagged fault is real to ~99.999%. ◆ iostat — I/O monitor & benchmark Live per-disk throughput, latency and IOPS, plus a Disk Health Scan that pinpoints the weak disk dragging down a whole RAID. ◆ DriveTime — SMART/FARM history An hourly collector builds a time-series of every disk’s attributes — see a value climbing before it trips a hard limit. ◆ iperf3 — network throughput Bandwidth and retransmits between two NAS units. ◆ vpn-diag — VPN diagnostics VPN link quality: MTU, jitter, loss, bandwidth and stability. ◆ Terminal (root) An interactive root shell on the NAS (admin only), through the daemon. ◆ Cheats & Utilities A palette of ready-to-run recovery/diagnostic commands (Storage, LVM, ZFS, System, Network…) you paste into the Terminal — no memorising. Requirements only QTS 5.2+ / QuTS hero
