Subject: [PATCH 1/2] fix: use actual memory usage excluding cache/buffers in
 monitoring

- Replace v.Used with (Total - Available) calculation
- Provides accurate memory usage for monitoring alerts
- Prevents false alerts caused by Linux cache/buffers
- Aligns with 'free -h' available memory metric
