+# NAS Doctor
+
+[NAS Doctor](https://github.com/mcdays94/nas-doctor) is a local diagnostic and monitoring tool for your NAS.
+It runs periodic health checks — analyzing SMART data, disk usage, Docker containers,
+GPU, process CPU usage, network speed, ZFS pools, UPS power, tunnels, and more — then
+surfaces findings with actionable recommendations backed by Backblaze failure rate data.
+
+## Features
+
+- 20+ diagnostic rules with automatic root-cause correlation
+- SMART health with Backblaze failure-rate thresholds (337k+ drives)
+- Top Processes with Docker container attribution (cgroup v1 and v2)
+- GPU monitoring (NVIDIA, Intel, AMD)
+- Network speed test scheduling (Ookla CLI)
+- Service checks (HTTP, TCP, DNS, Ping/ICMP, SMB, NFS, Speed)
+- ZFS pool health, UPS/power monitoring
+- Webhook alerts (Discord, Slack, Gotify, Ntfy)
+- Prometheus metrics endpoint
+- Multi-server fleet monitoring
+
+## Notes
+
+- Requires privileged access (`SYS_RAWIO` capability) for SMART health monitoring
+- Host PID namespace sharing is enabled so Top Processes can see all host processes
+  and match them to Docker containers via cgroup data
+- `/dev` and `/sys` are mounted read-only for device access and GPU telemetry
