⚡ Bolt: Optimize swap-ssd-health.sh parsing and fix calculation bugs - #4
Conversation
…ugs: - Replaced multiple subprocess chains with single awk passes for `sysctl`, `vm_stat`, and `smartctl` parsing. - Fixed a bug where `USED_SWAP` was incorrectly extracting the `TOTAL_SWAP` value (field $4 vs field $7). - Fixed a case sensitivity issue with 'Pageouts' detection in `vm_stat`. - Improved error handling for missing SMART attributes.

💡 What: Optimized
ops/monitoring/swap-ssd-health.shto use efficient single-passawkparsing instead of multiple pipeline chains. Fixed critical bugs in swap usage calculation and pageouts detection.🎯 Why:
USED_SWAPwas incorrectly parsing field $4 (total) instead of field $7 (used), leading to 100% swap usage reports.vm_statoutput for 'Pageouts' varies in case across macOS versions; added case-insensitive matching.📊 Impact:
🔬 Measurement:
Verified using a test harness (
tests/test_swap_ssd_health.sh) that mockedsysctl,vm_stat,diskutil, andsmartctloutput to confirm correct parsing and calculation logic.PR created automatically by Jules for task 2568319239102810731 started by @simien
