FreeBSD disk discovery now falls back to scanning /dev for ada*, da*,
nvd*, nda* and other FreeBSD disk names when kern.disks misses them.
Probe order prefers the correct device type first (sat for ada, nvme
for nvd). Standby disks are preserved as valid results instead of
being dropped.
ZFS zvols (zd*), device-mapper, virtio disks, and other virtual block
devices don't support SMART and were being reported as FAILED. Use lsblk
JSON metadata to filter by device prefix, transport, subsystem, and
vendor/model. Also treat missing smart_status as unknown rather than
failed, and ignore UNKNOWN health in Patrol/AI signals.
Seagate drives pack vendor-specific data in the upper bytes of the
48-bit SMART raw value, causing Power_On_Hours to report billions of
years instead of the actual value. Use smartctl's raw.string field
(e.g. "16951 (223 173 0)") and extract the first integer, which is
the correct interpretation. Falls back to raw.value when the string
is empty or non-numeric.
Expand the smartctl collector to capture detailed SMART attributes (SATA
and NVMe), propagate them through the full data pipeline, persist them
as time-series metrics, and display them in an interactive disk detail
drawer with historical sparkline charts.
Backend: add SMARTAttributes struct, writeSMARTMetrics for persistent
storage, "disk" resource type in metrics API with live fallback.
Frontend: enhanced DiskList with Power-On column and SMART warnings,
new DiskDetail drawer matching NodeDrawer styling patterns, generic
HistoryChart metric support with proper tooltip formatting.
Previously, the PULSE_DISK_EXCLUDE environment variable and --disk-exclude
flag only filtered mount points in the hostmetrics collector. This change
extends the exclusion to SMART data collection.
Changes:
- Updated smartctl.CollectLocal() to accept diskExclude patterns
- Added matchesDeviceExclude() for block device pattern matching
- Patterns support: exact match (sda), prefix (nvme*), contains (*cache*)
- Updated hostagent to pass DiskExclude to SMART collector
- Added comprehensive tests for pattern matching
- Updated documentation
