SDLV

Silas Diagnostic Log Viewer (SDLV) The QNAP NAS diagnostic workbench — turn a diagnostic ZIP into a root-cause, right in your browser. QNAP support cases usually start the same way: a customer sends a diagnostic bundle, and you’re left scrolling through a 20 MB klogd_dump.log, an 80,000-line event CSV, dozens of SMART files and a sprawling HTML report — in separate tabs, by hand. SDLV collapses all of that into a single desktop-style dashboard. Upload the diagnostic ZIP and SDLV extracts it, detects the device(s) and firmware, and fans the contents out into ~25 purpose-built viewers — each a draggable, resizable window. Everything is cross-linked: a SMART-critical disk in the title bar jumps you to the drive card; an OOM event links to the offending process; an incident on the timeline expands into the exact kernel and event-log lines that produced it. Behind every viewer is a curated pattern engine: 180+ hand-built signatures (ATA link failures, NCQ errors, uncorrectable reads, RAID degradation, filesystem and controller faults, and more) matched live against the kernel and event logs, each tagged critical / warning / info with an explanation of cause and impact. Edit, import and export the whole set from the built-in Pattern Editor. And when you have live access to the NAS, the optional privileged daemon turns SDLV from a post-mortem tool into a live lab — fio benchmarks, iperf3 transfers, streaming iostat, RAM surface scans and VPN/MTU probes, all in the same dashboard. Who it’s for QNAP support engineers & resellers triaging customer diagnostic bundles NAS administrators & homelab power users chasing a flaky disk, an OOM, or a network stall Storage / data-recovery specialists who need fast, trustworthy SMART, RAID and pool topology reads 🩺 Dr. Trace — incident correlation timeline The signature view. SDLV merges the kernel log and the full event log onto one zoomable lifeline spanning the machine’s whole history, then auto-groups the noise into incidents across power · storage · network · SMART · system lanes. A movie-cut scrubber replays the exact window around a failure, with the merged log pinned below. 💽 S.M.A.R.T. Disk Health Brand-aware drive cards (Seagate, WD, Toshiba… logos resolved automatically), QNAP HCL verification, enclosure/slot mapping, and expert per-attribute tooltips that explain each attribute’s cause, impact and vendor-specific interpretation — so “Seek Error Rate 79” becomes an actual decision. 🗄️ Storage topology — LVM · DRBD · ZFS · RAID SSD-cache groups with mode (Read-Only / Read-Write), per-enclosure drive maps with capacity and type badges (NVMe / Enterprise / consumer), software RAID (mdstat) arrays and DRBD resources — the whole storage stack at a glance. 🧠 Memory & OOM · 🧩 Process Explorer RAM/swap bars, a full DIMM inventory with mixed-capacity warnings, and decoded OOM-killer events — plus a process tree of hundreds of processes grouped into readable kernel-thread families, with live per-core CPU and zombie / OOM-kill counters. 🔎 Pattern engine + editor 180+ failure signatures matched live in dmesg and log_tool, organised by severity. Add, edit, enable/disable, and import/export the entire set as JSON — your detection knowledge becomes a portable asset. ⚡ Live diagnostics (optional on-NAS daemon) Same dashboard, live machine: Storage Benchmark (fio) — per-volume presets (sequential / random, queue depths, file size) iostat streaming — live per-device await / IOPS / throughput / utilization charts iperf3 — auto-discover or manual targets, client/server, multi-stream throughput memhound — RAM surface scanner with a live memory map (x86_64 / aarch64 / armhf) vpn-diag — link/latency/MTU/MSS probe with a health score and actionable warnings Everything in the box (~25 viewers) Group Viewers Logs & timeline Kernel Log (dmesg), Event Log, Var Logs, Crash Dump, Dr. Trace, Timeline, Diagnostic Insight Storage S.M.A.R.T.
