Problem: Drive capacity was being extracted but never inserted into ticket titles.
The drive_size variable was calculated from drive details but omitted from the
ticket_title string construction.
Solution: Added drive_size to ticket title format between category and issue.
Example ticket titles now show:
- Before: "[hostname][auto][hardware]Drive /dev/sda has SMART issues..."
- After: "[hostname][auto][hardware][16.0 TB] Drive /dev/sda has SMART issues..."
This makes it easier to identify which drives need attention at a glance.

Added comprehensive manual execution section with both:
- Direct execution from local file (python3 hwmonDaemon.py)
- Remote execution matching systemd service (one-liner download+exec)
Both modes include dry-run and normal execution examples for testing
and production use.

Problem: Seagate drives were triggering tickets for "Critical Seek_Error_Rate"
and "Critical Command_Timeout" even though these are operation counters used by
the manufacturer, not actual errors.
Solution: Added filtering in _detect_issues() method to skip known manufacturer
operation counters:
- Seek_Error_Rate (Seagate/WD operation counter)
- Command_Timeout (OOS/Seagate operation counter)
- Raw_Read_Error_Rate (Seagate/WD operation counter)
These attributes are already correctly excluded from monitoring in manufacturer
profiles, but were still appearing in smart_issues list. This fix prevents them
from creating tickets while still catching legitimate SMART errors.
Changes:
- hwmonDaemon.py:1351-1378 - Added operation counter filtering in _detect_issues()
- Added debug logging when filtering manufacturer counters

Critical fixes implemented:
- Add 10MB storage limit with automatic cleanup of old history files
- Add file locking (fcntl) to prevent race conditions in history writes
- Disable SMART monitoring for unreliable Ridata drives
- Fix bare except clause in _read_ecc_count() to properly catch errors
- Add timeouts to all network and subprocess calls (10s for API, 30s for subprocess)
- Fix unchecked regex in ticket creation to prevent AttributeError
- Add JSON decode error handling for ticket API responses
Service configuration improvements:
- hwmon.timer: Reduce jitter from 300s to 60s, add Persistent=true
- hwmon.service: Add Restart=on-failure, TimeoutStartSec=300, logging to journal
These changes improve reliability, prevent hung processes, eliminate race
conditions, and add proper error handling throughout the daemon.
