useless as a monitoring tool. +### βœ… All Phases Completed Successfully -### Complete Fix Plan - Do Everything Right +#### βœ… Phase 1: Storage Display - COMPLETED +- βœ… Use `lsblk` instead of `findmnt` (eliminated `/nix/store` bind mount issue) +- βœ… Add `sudo smartctl` for permissions (SMART data collection working) +- βœ… Fix NVMe SMART parsing (`Temperature:` and `Percentage Used:` fields) +- βœ… Consistent filesystem/tmpfs sorting (no more random order swapping) +- βœ… **VERIFIED**: Dashboard shows `● nvme0n1 T: 28Β°C W: 1%` correctly -#### Phase 1: Fix Storage Display (CURRENT) -- βœ… Use `lsblk` instead of `findmnt` (eliminates `/nix/store` bind mount issue) -- βœ… Add `sudo smartctl` for permissions -- βœ… Fix NVMe SMART parsing (`Temperature:` and `Percentage Used:`) -- πŸ”„ Test that dashboard shows: `● nvme0n1 T: 28Β°C W: 1%` correctly +#### βœ… Phase 2: Status Evaluation System - COMPLETED +- βœ… **CPU Status**: Load averages and temperature evaluated against `HysteresisThresholds` +- βœ… **Memory Status**: Usage percentage evaluated against thresholds +- βœ… **Storage Status**: Drive temperature, health, and filesystem usage evaluated +- βœ… **Service Status**: Service states properly tracked and evaluated +- βœ… **Status Fields**: All AgentData structures include status information +- βœ… **Threshold Integration**: All collectors use their configured thresholds -#### Phase 2: Restore Status Evaluation System -- **CPU Status**: Evaluate load averages against thresholds β†’ Status::Warning/Critical -- **Memory Status**: Evaluate
