When the top-level temperature.current field is 0 or missing (common
on some SATA drives), temperature was reported as 0°C with no fallback.
Now extracts temperature from ATA SMART attribute 194 (Temperature_Celsius)
or 190 (Airflow_Temperature_Cel) as a fallback.
Fixes#1243
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.
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.
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
