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.
Relax the Linux-only gate on SMART collection to also run on FreeBSD.
Add FreeBSD disk discovery via sysctl kern.disks (lsblk is Linux-only).
The smartctl invocation and JSON parsing are already platform-agnostic.
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
