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
- Add smartctl package to collect disk temperature and health data
- Add SMART field to agent Sensors struct
- Host agent now runs smartctl to collect disk temps when available
- Backend processes agent SMART data for temperature display
- Graceful fallback when smartctl not installed
