- Storage: drive SMART degradation, RAID state, NVMe wear, NVMe Critical Warning, I/O errors, latency
- ZFS: pool health, scrub errors, SLOG faulted
- Filesystem: capacity, projection, inodes, read-only mounts, fd exhaustion, LVM thin metadata
- Memory & CPU: utilisation, swap, OOM kills, load, iowait, PSI pressure
- Network: bonding/LACP, interface errors, saturation, link speed, conntrack, retrans, listen overflow, syn flood, softnet drops
- Hardware (BMC/IPMI): CPU temperature, ECC, MCE, PSU redundancy, SEL events, fan failure
- GPU: XID, ECC, thermal, NVLink, PCIe degradation, driver drift, power cap throttling (NVIDIA, Crucible v0.13.0+)
- Time & Services: clock drift, NTP, systemd service state, service flapping, unexpected reboot
- Security & Patching: SSH root, firewall, pending updates, kernel vulnerabilities, reboot pending, unattended-upgrades, server unreachable
