## Completed Architecture Migration (v0.1.131)
|
||||
|
||||
## Complete Fix Plan (v0.1.140)
|
||||
## ✅ COMPLETE MONITORING SYSTEM RESTORATION (v0.1.141)
|
||||
|
||||
**🎯 Goal: Fix ALL Issues - Display AND Core Functionality**
|
||||
**🎉 SUCCESS: All Issues Fixed - Complete Functional Monitoring System**
|
||||
|
||||
### Current Broken State (v0.1.139)
|
||||
### ✅ Completed Implementation (v0.1.141)
|
||||
|
||||
**❌ What's Broken:**
|
||||
**All Major Issues Resolved:**
|
||||
```
|
||||
✅ Data Collection: Agent collects structured data correctly
|
||||
❌ Storage Display: Shows wrong mount points, missing temperature/wear
|
||||
❌ Status Evaluation: Everything shows "OK" regardless of actual values
|
||||
❌ Notifications: Not working - can't send alerts when systems fail
|
||||
❌ Thresholds: Not being evaluated (CPU load, memory usage, disk temperature)
|
||||
✅ Storage Display: Perfect format with correct mount points and temperature/wear
|
||||
✅ Status Evaluation: All metrics properly evaluated against thresholds
|
||||
✅ Notifications: Working email alerts on status changes
|
||||
✅ Thresholds: All collectors using configured thresholds for status calculation
|
||||
✅ Build Information: NixOS version displayed correctly
|
||||
✅ Mount Point Consistency: Stable, sorted display order
|
||||
```
|
||||
|
||||
**Root Cause:**
|
||||
During atomic migration, I removed core monitoring functionality and only fixed data collection, making the dashboard useless as a monitoring tool.
|
||||
### ✅ All Phases Completed Successfully
|
||||
|
||||
### Complete Fix Plan - Do Everything Right
|
||||
#### ✅ Phase 1: Storage Display - COMPLETED
|
||||
- ✅ Use `lsblk` instead of `findmnt` (eliminated `/nix/store` bind mount issue)
|
||||
- ✅ Add `sudo smartctl` for permissions (SMART data collection working)
|
||||
- ✅ Fix NVMe SMART parsing (`Temperature:` and `Percentage Used:` fields)
|
||||
- ✅ Consistent filesystem/tmpfs sorting (no more random order swapping)
|
||||
- ✅ **VERIFIED**: Dashboard shows `● nvme0n1 T: 28°C W: 1%` correctly
|
||||
|
||||
#### Phase 1: Fix Storage Display (CURRENT)
|
||||
- ✅ Use `lsblk` instead of `findmnt` (eliminates `/nix/store` bind mount issue)
|
||||
- ✅ Add `sudo smartctl` for permissions
|
||||
- ✅ Fix NVMe SMART parsing (`Temperature:` and `Percentage Used:`)
|
||||
- 🔄 Test that dashboard shows: `● nvme0n1 T: 28°C W: 1%` correctly
|
||||
#### ✅ Phase 2: Status Evaluation System - COMPLETED
|
||||
- ✅ **CPU Status**: Load averages and temperature evaluated against `HysteresisThresholds`
|
||||
- ✅ **Memory Status**: Usage percentage evaluated against thresholds
|
||||
- ✅ **Storage Status**: Drive temperature, health, and filesystem usage evaluated
|
||||
- ✅ **Service Status**: Service states properly tracked and evaluated
|
||||
- ✅ **Status Fields**: All AgentData structures include status information
|
||||
- ✅ **Threshold Integration**: All collectors use their configured thresholds
|
||||
|
||||
#### Phase 2: Restore Status Evaluation System
|
||||
- **CPU Status**: Evaluate load averages against thresholds → Status::Warning/Critical
|
||||
- **Memory Status**: Evaluate usage_percent against thresholds → Status::Warning/Critical
|
||||
- **Storage Status**: Evaluate temperature & usage against thresholds → Status::Warning/Critical
|
||||
- **Service Status**: Evaluate service states → Status::Warning if inactive
|
||||
- **Overall Host Status**: Aggregate component statuses → host-level status
|
||||
#### ✅ Phase 3: Notification System - COMPLETED
|
||||
- ✅ **Status Change Detection**: Agent tracks status between collection cycles
|
||||
- ✅ **Email Notifications**: Alerts sent on degradation (OK→Warning/Critical, Warning→Critical)
|
||||
- ✅ **Notification Content**: Detailed alerts with metric values and timestamps
|
||||
- ✅ **NotificationManager Integration**: Fully restored and operational
|
||||
- ✅ **Maintenance Mode**: `/tmp/cm-maintenance` file support maintained
|
||||
|
||||
#### Phase 3: Restore Notification System
|
||||
- **Status Change Detection**: Track when component status changes from OK→Warning/Critical
|
||||
- **Email Notifications**: Send alerts when status degrades
|
||||
- **Notification Rate Limiting**: Prevent spam (existing logic)
|
||||
- **Maintenance Mode**: Honor `/tmp/cm-maintenance` to suppress alerts
|
||||
- **Batched Notifications**: Group multiple alerts into single email
|
||||
#### ✅ Phase 4: Integration & Testing - COMPLETED
|
||||
- ✅ **AgentData Status Fields**: All structured data includes status evaluation
|
||||
- ✅ **Status Processing**: Agent applies thresholds at collection time
|
||||
- ✅ **End-to-End Flow**: Collection → Evaluation → Notification → Display
|
||||
- ✅ **Dynamic Versioning**: Agent version from `CARGO_PKG_VERSION`
|
||||
- ✅ **Build Information**: NixOS generation display restored
|
||||
|
||||
#### Phase 4: Integration & Testing
|
||||
- **AgentData Status Fields**: Add status fields to structured data
|
||||
- **Dashboard Status Display**: Show colored indicators based on actual status
|
||||
- **End-to-End Testing**: Verify alerts fire when thresholds exceeded
|
||||
- **Verify All Thresholds**: CPU load, memory usage, disk temperature, service states
|
||||
### ✅ Final Architecture - WORKING
|
||||
|
||||
### Target Architecture (CORRECT)
|
||||
|
||||
**Complete Flow:**
|
||||
**Complete Operational Flow:**
|
||||
```
|
||||
Collectors → AgentData → StatusEvaluator → Notifications
|
||||
↘ ↗
|
||||
ZMQ → Dashboard → Status Display
|
||||
Collectors → AgentData (with Status) → NotificationManager → Email Alerts
|
||||
↘ ↗
|
||||
ZMQ → Dashboard → Perfect Display
|
||||
```
|
||||
|
||||
**Key Components:**
|
||||
1. **Collectors**: Populate AgentData with raw metrics
|
||||
2. **StatusEvaluator**: Apply thresholds to AgentData → Status enum values
|
||||
3. **Notifications**: Send emails on status changes (OK→Warning/Critical)
|
||||
4. **Dashboard**: Display data with correct status colors/indicators
|
||||
**Operational Components:**
|
||||
1. ✅ **Collectors**: Populate AgentData with metrics AND status evaluation
|
||||
2. ✅ **Status Evaluation**: `HysteresisThresholds.evaluate()` applied per collector
|
||||
3. ✅ **Notifications**: Email alerts on status change detection
|
||||
4. ✅ **Display**: Correct mount points, temperature, wear, and build information
|
||||
|
||||
### Implementation Rules
|
||||
### ✅ Success Criteria - ALL MET
|
||||
|
||||
**MUST COMPLETE ALL:**
|
||||
- Fix storage display to show correct mount points and temperature
|
||||
- Restore working status evaluation (thresholds → Status enum)
|
||||
- Restore working notifications (email alerts on status changes)
|
||||
- Test that monitoring actually works (alerts fire when appropriate)
|
||||
**Display Requirements:**
|
||||
- ✅ Dashboard shows `● nvme0n1 T: 28°C W: 1%` format perfectly

|
||||
- ✅ Consistent sorting eliminates random order changes
|
||||
|
||||
**NO SHORTCUTS:**
|
