Fix user-stopped flag timing and service transition handling

Correct user-stopped service behavior during startup transitions: User-Stopped Flag Timing Fix: - Clear user-stopped flag only when service actually becomes active, not when start command succeeds - Remove premature flag clearing from service control handler - Add automatic flag clearing when service status metrics show active state - Services retain user-stopped status during activating/transitioning states Service Transition Handling: - User-stopped services in activating state now report Status::OK instead of Status::Pending - Prevents host warnings during legitimate service startup transitions - Maintains accurate status reporting throughout service lifecycle - Failed service starts preserve user-stopped flags correctly Journalctl Popup Fix: - Fix terminal corruption when using J key for service logs - Correct command quoting to prevent tmux popup interference - Stable popup display without dashboard interface corruption Result: Clean service startup experience with no false warnings and proper user-stopped tracking throughout the entire service lifecycle. Bump version to v0.1.47
Add service logs feature and improve tmux popup sizing

 ### Current Simplified Navigation Implementation
 **Navigation Controls:**
 - **Tab**: Switch between hosts (cmbox, srv01, srv02, steambox, etc.)
 - **↑↓ or j/k**: Move service selection cursor (always works)
 - **q**: Quit dashboard
-**Service Control:**
+## Core Architecture Principles
 - **s**: Start selected service
 - **S**: Stop selected service  
 - **R**: Rebuild current host (works from any context)
 **Visual Features:**
 - **Service Selection**: Always visible blue background highlighting current service
 - **Status Icons**: Green ● (active), Yellow ◐ (inactive), Red ◯ (failed), ? (unknown)
 - **Transitional Icons**: Blue ↑ (starting), ↓ (stopping), ↻ (restarting) when not selected
 - **Transitional Icons**: Dark gray arrows when service is selected (for visibility)
 - **Uniform Interface**: All panels have consistent appearance (no focus borders)
 ### Service Discovery and Display - WORKING ✅
 **All Issues Resolved (as of 2025-10-28):**
 - ✅ **Complete Service Discovery**: Uses `systemctl list-unit-files` + `list-units --all` for comprehensive service detection
 - ✅ **All Services Visible**: Shows all configured services regardless of current state (active/inactive)
 - ✅ **Proper Status Display**: Active services show green ●, inactive show yellow ◐, failed show red ◯
 - ✅ **Transitional Icons**: Visual feedback during service operations with proper color handling
 - ✅ **Simplified Navigation**: Removed panel complexity, direct service control always available
 - ✅ **Service Control**: Start (s) and Stop (S) commands work from anywhere
 - ✅ **System Rebuild**: SSH + tmux popup approach for reliable remote rebuilds
 ### Terminal Popup for Real-time Output - IMPLEMENTED ✅
 **Status (as of 2025-10-26):**
 - ✅ **Terminal Popup UI**: 80% screen coverage with terminal styling and color-coded output
 - ✅ **ZMQ Streaming Protocol**: CommandOutputMessage for real-time output transmission
 - ✅ **Keyboard Controls**: ESC/Q to close, ↑↓ to scroll, manual close (no auto-close)
 - ✅ **Real-time Display**: Live streaming of command output as it happens
 - ✅ **Version-based Agent Reporting**: Shows "Agent: v0.1.13" instead of nix store hash
 **Current Implementation Issues:**
 - ❌ **Agent Process Crashes**: Agent dies during nixos-rebuild execution
 - ❌ **Inconsistent Output**: Different outputs each time 'R' is pressed
 - ❌ **Limited Output Visibility**: Not capturing all nixos-rebuild progress
 **PLANNED SOLUTION - Systemd Service Approach:**
 **Problem**: Direct nixos-rebuild execution in agent causes process crashes and inconsistent output.
 **Solution**: Create dedicated systemd service for rebuild operations.
 **Implementation Plan:**
 1. **NixOS Systemd Service**:
   ```nix
   systemd.services.cm-rebuild = {
     description = "CM Dashboard NixOS Rebuild";
     serviceConfig = {
       Type = "oneshot";
       ExecStart = "${pkgs.nixos-rebuild}/bin/nixos-rebuild switch --flake . --option sandbox false";
       WorkingDirectory = "/var/lib/cm-dashboard/nixos-config";
       User = "root";
       StandardOutput = "journal";
       StandardError = "journal";
     };
   };
   ```
 2. **Agent Modification**:
   - Replace direct nixos-rebuild execution with: `systemctl start cm-rebuild`
   - Stream output via: `journalctl -u cm-rebuild -f --no-pager`
   - Monitor service status for completion detection
 3. **Benefits**:
   - **Process Isolation**: Service runs independently, won't crash agent
   - **Consistent Output**: Always same deterministic rebuild process
   - **Proper Logging**: systemd journal handles all output management
   - **Resource Management**: systemd manages cleanup and resource limits
   - **Status Tracking**: Can query service status (running/failed/success)
 **Next Priority**: Implement systemd service approach for reliable rebuild operations.
 **Keyboard Controls Status:**
 - **Services Panel**: 
  - R (restart) ✅ Working
  - s (start) ✅ Working  
  - S (stop) ✅ Working
 - **System Panel**: R (nixos-rebuild) ✅ Working with --option sandbox false
 - **Backup Panel**: B (trigger backup) ❓ Not implemented
 **Visual Feedback Implementation - IN PROGRESS:**
 Context-appropriate progress indicators for each panel:
 **Services Panel** (Service status transitions):
 ```
 ● nginx          active    →  ⏳ nginx      restarting  →  ● nginx          active
 ● docker         active    →  ⏳ docker     stopping    →  ● docker         inactive  
 ```
 **System Panel** (Build progress in NixOS section):
 ```
 NixOS:
 Build: 25.05.20251004.3bcc93c    →    Build: [████████████     ] 65%
 Active users: cm, simon               Active users: cm, simon
 ```
 **Backup Panel** (OnGoing status with progress):
 ```
 Latest backup:              →    Latest backup:
 ● 2024-10-23 14:32:15            ● OnGoing  
 └─ Duration: 1.3m                 └─ [██████       ] 60%
 ```
 **Critical Configuration Hash Fix - HIGH PRIORITY:**
 **Problem:** Configuration hash currently shows git commit hash instead of actual deployed system hash.
 **Current (incorrect):** 
 - Shows git hash: `db11f82` (source repository commit)
 - Not accurate - doesn't reflect what's actually deployed
 **Target (correct):**
 - Show nix store hash: `d8ivwiar` (first 8 chars from deployed system)  
 - Source: `/nix/store/d8ivwiarhwhgqzskj6q2482r58z46qjf-nixos-system-cmbox-25.05.20251004.3bcc93c`
 - Pattern: Extract hash from `/nix/store/HASH-nixos-system-HOSTNAME-VERSION`
 **Benefits:**
 1. **Deployment Verification:** Confirms rebuild actually succeeded
 2. **Accurate Status:** Shows what's truly running, not just source
 3. **Rebuild Completion Detection:** Hash change = rebuild completed
 4. **Rollback Tracking:** Each deployment has unique identifier
 **Implementation Required:**
 1. Agent extracts nix store hash from `ls -la /run/current-system` 
 2. Reports this as `system_config_hash` metric instead of git hash
 3. Dashboard displays first 8 characters: `Config: d8ivwiar`
 **Next Session Priority Tasks:**
 **Remaining Features:**
 1. **Fix Configuration Hash Display (CRITICAL)**:
   - Use nix store hash instead of git commit hash
   - Extract from `/run/current-system` -> `/nix/store/HASH-nixos-system-*`
   - Enables proper rebuild completion detection
 2. **Command Response Protocol**:
   - Agent sends command completion/failure back to dashboard via ZMQ
   - Dashboard updates UI status from ⏳ to ● when commands complete
   - Clear success/failure status after timeout
 3. **Backup Panel Features**:
   - Implement backup trigger functionality (B key)
   - Complete visual feedback for backup operations
   - Add backup progress indicators
 **Enhancement Tasks:**
 - Add confirmation dialogs for destructive actions (stop/restart/rebuild)
 - Implement command history/logging
 - Add keyboard shortcuts help overlay
 **Future Enhanced Navigation:**
 - Add Page Up/Down for faster scrolling through long service lists
 - Implement search/filter functionality for services
 - Add jump-to-service shortcuts (first letter navigation)
 **Future Advanced Features:**
 - Service dependency visualization
 - Historical service status tracking
 - Real-time log viewing integration
 ## Core Architecture Principles - CRITICAL
 ### Individual Metrics Philosophy
-
+- Agent collects individual metrics, dashboard composes widgets
-**NEW ARCHITECTURE**: Agent collects individual metrics, dashboard composes widgets from those metrics.
+- Each metric collected, transmitted, and stored individually
 - Agent calculates status for each metric using thresholds
 - Dashboard aggregates individual metric statuses for widget status
 ### Maintenance Mode
 **Purpose:**
 - Suppress email notifications during planned maintenance or backups
 - Prevents false alerts when services are intentionally stopped
 **Implementation:**
 - Agent checks for `/tmp/cm-maintenance` file before sending notifications
 - File presence suppresses all email notifications while continuing monitoring
 - Dashboard continues to show real status, only notifications are blocked
-**Usage:**
+Usage:
 ```bash
 # Enable maintenance mode
 touch /tmp/cm-maintenance
-# Run maintenance tasks (backups, service restarts, etc.)
+# Run maintenance tasks
 systemctl stop service

 ## Automated Binary Release System
 **IMPLEMENTED:** cm-dashboard now uses automated binary releases instead of source builds.
 ### Release Workflow
 1. **Automated Release Creation**
   - Gitea Actions workflow builds static binaries on tag push
   - Creates release with `cm-dashboard-linux-x86_64.tar.gz` tarball
   - No manual intervention required for binary generation
 2. **Creating New Releases**
   ```bash
   cd ~/projects/cm-dashboard
   git tag v0.1.X
   git push origin v0.1.X
   ```
   This automatically:
   - Builds static binaries with `RUSTFLAGS="-C target-feature=+crt-static"`
   - Creates GitHub-style release with tarball
   - Uploads binaries via Gitea API
 3. **NixOS Configuration Updates**
   Edit `~/projects/nixosbox/hosts/common/cm-dashboard.nix`:
   ```nix
   version = "v0.1.X";
   src = pkgs.fetchurl {
     url = "https://gitea.cmtec.se/cm/cm-dashboard/releases/download/${version}/cm-dashboard-linux-x86_64.tar.gz";
     sha256 = "sha256-NEW_HASH_HERE";
   };
   ```
 4. **Get Release Hash**
   ```bash
   cd ~/projects/nixosbox
   nix-build --no-out-link -E 'with import <nixpkgs> {}; fetchurl {
     url = "https://gitea.cmtec.se/cm/cm-dashboard/releases/download/v0.1.X/cm-dashboard-linux-x86_64.tar.gz";
     sha256 = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
   }' 2>&1 | grep "got:"
   ```
 5. **Commit and Deploy**
   ```bash
   cd ~/projects/nixosbox
   git add hosts/common/cm-dashboard.nix
   git commit -m "Update cm-dashboard to v0.1.X with static binaries"
   git push
   ```
 ### Benefits
 - **No compilation overhead** on each host
 - **Consistent static binaries** across all hosts
 - **Faster deployments** - download vs compile
 - **No library dependency issues** - static linking
 - **Automated pipeline** - tag push triggers everything

 # CM Dashboard
-A real-time infrastructure monitoring system with intelligent status aggregation and email notifications, built with Rust and ZMQ.
+A high-performance Rust-based TUI dashboard for monitoring CMTEC infrastructure. Built with ZMQ-based metric collection and individual metrics architecture.
-## Current Implementation
+## Features
-This is a complete rewrite implementing an **individual metrics architecture** where:
+### Core Monitoring
 - **Real-time metrics**: CPU, RAM, Storage, and Service status
 - **Multi-host support**: Monitor multiple servers from single dashboard  
 - **Service management**: Start/stop services with intelligent status tracking
 - **NixOS integration**: System rebuild via SSH + tmux popup
 - **Backup monitoring**: Borgbackup status and scheduling
 - **Email notifications**: Intelligent batching prevents spam
- **Agent** collects individual metrics (e.g., `cpu_load_1min`, `memory_usage_percent`) and calculates status
+### User-Stopped Service Tracking
- **Dashboard** subscribes to specific metrics and composes widgets
+Services stopped via the dashboard are intelligently tracked to prevent false alerts:
 - **Status Aggregation** provides intelligent email notifications with batching
 - **Persistent Cache** prevents false notifications on restart
-## Dashboard Interface
+- **Smart status reporting**: User-stopped services show as Status::OK instead of Warning
 - **Persistent storage**: Tracking survives agent restarts via JSON storage
 - **Automatic management**: Flags cleared when services restarted via dashboard
 - **Maintenance friendly**: No false alerts during intentional service operations
 ## Architecture
 ### Individual Metrics Philosophy
 - **Agent**: Collects individual metrics, calculates status using thresholds
 - **Dashboard**: Subscribes to specific metrics, composes widgets from individual data
 - **ZMQ Communication**: Efficient real-time metric transmission
 - **Status Aggregation**: Host-level status calculated from all service metrics

 └─────────────────┘            └─────────────────┘
 ```
 ### Service Control Flow
 1. **User Action**: Dashboard sends `UserStart`/`UserStop` commands
 2. **Agent Processing**: 
   - Marks service as user-stopped (if stopping)
   - Executes `systemctl start/stop service`
   - Syncs state to global tracker
 3. **Status Calculation**: 
   - Systemd collector checks user-stopped flag
   - Reports Status::OK for user-stopped inactive services
   - Normal Warning status for system failures

-## Collectors
+## Technical Implementation
-The agent implements several specialized collectors:
+### Collectors
-### CPU Collector (`cpu.rs`)
+#### Systemd Collector
 - **Service Discovery**: Uses `systemctl list-unit-files` + `list-units --all`
 - **Status Calculation**: Checks user-stopped flag before assigning Warning status
 - **Memory Tracking**: Per-service memory usage via `systemctl show`
 - **Sub-services**: Nginx site latency, Docker containers
 - **User-stopped Integration**: `UserStoppedServiceTracker::is_service_user_stopped()`
- Load average (1, 5, 15 minute)
+#### User-Stopped Service Tracker
- CPU temperature monitoring
+- **Storage**: `/var/lib/cm-dashboard/user-stopped-services.json`
- Real-time process monitoring (top CPU consumers)
+- **Thread Safety**: Global singleton with `Arc<Mutex<>>`
- Status calculation with configurable thresholds
+- **Persistence**: Automatic save on state changes
 - **Global Access**: Static methods for collector integration
-### Memory Collector (`memory.rs`)
+#### Other Collectors
 - **CPU**: Load average, temperature, frequency monitoring
 - **Memory**: RAM/swap usage, tmpfs monitoring  
 - **Disk**: Filesystem usage, SMART health data
 - **NixOS**: Build version, active users, agent version
 - **Backup**: Borgbackup repository status and metrics
- RAM usage (total, used, available)
+### ZMQ Protocol
 - Swap monitoring
 - Real-time process monitoring (top RAM consumers)
 - Memory pressure detection
-### Disk Collector (`disk.rs`)
+```rust
 // Metric Message
 #[derive(Serialize, Deserialize)]
 pub struct MetricMessage {
    pub hostname: String,
    pub timestamp: u64,
    pub metrics: Vec<Metric>,
 }
- Filesystem usage per mount point
+// Service Commands
- SMART health monitoring
+pub enum AgentCommand {
- Temperature and wear tracking
+    ServiceControl {
- Configurable filesystem monitoring
+        service_name: String,
        action: ServiceAction,
    },
    SystemRebuild { /* SSH config */ },
    CollectNow,
 }
-### Systemd Collector (`systemd.rs`)
+pub enum ServiceAction {
    Start,           // System-initiated
    Stop,            // System-initiated  
    UserStart,       // User via dashboard (clears user-stopped)
    UserStop,        // User via dashboard (marks user-stopped)
    Status,
 }
 ```
- Service status monitoring (`active`, `inactive`, `failed`)
+### Maintenance Mode
 - Memory usage per service
 - Service filtering and exclusions
 - Handles transitional states (`Status::Pending`)
-### Backup Collector (`backup.rs`)
+Suppress notifications during planned maintenance:
- Reads TOML status files from backup systems
+```bash
- Archive age verification
+# Enable maintenance mode
- Disk usage tracking
+touch /tmp/cm-maintenance
- Repository health monitoring
+
 # Perform maintenance
 systemctl stop service
 # ... work ...
 systemctl start service  
 # Disable maintenance mode
 rm /tmp/cm-maintenance
 ```
 ## Email Notifications
 ### Intelligent Batching
 - **Real-time dashboard**: Immediate status updates
 - **Batched emails**: Aggregated every 30 seconds
 - **Smart grouping**: Services organized by severity
 - **Recovery suppression**: Reduces notification spam
-The system implements smart notification batching to prevent email spam:
+### Example Alert
 - **Real-time dashboard updates** - Status changes appear immediately
 - **Batched email notifications** - Aggregated every 30 seconds
 - **Detailed groupings** - Services organized by severity
 ### Example Alert Email
 ```
-Subject: Status Alert: 2 critical, 1 warning, 15 started
+Subject: Status Alert: 1 critical, 2 warnings, 0 recoveries
 Status Summary (30s duration)
 Host Status: Ok → Warning
-🔴 CRITICAL ISSUES (2):
+🔴 CRITICAL ISSUES (1):
-  postgresql: Ok → Critical
+  postgresql: Ok → Critical (memory usage 95%)

 ## Individual Metrics Architecture
 The system follows a **metrics-first architecture**:
 ### Agent Side
 ```rust
 // Agent collects individual metrics
 vec![
    Metric::new("cpu_load_1min".to_string(), MetricValue::Float(2.5), Status::Ok),
    Metric::new("memory_usage_percent".to_string(), MetricValue::Float(78.5), Status::Warning),
    Metric::new("service_nginx_status".to_string(), MetricValue::String("active".to_string()), Status::Ok),
 ]
 ```
 ### Dashboard Side
 ```rust
 // Widgets subscribe to specific metrics
 impl Widget for CpuWidget {
    fn update_from_metrics(&mut self, metrics: &[&Metric]) {
        for metric in metrics {
            match metric.name.as_str() {
                "cpu_load_1min" => self.load_1min = metric.value.as_f32(),
                "cpu_load_5min" => self.load_5min = metric.value.as_f32(),
                "cpu_temperature_celsius" => self.temperature = metric.value.as_f32(),
                _ => {}
            }
        }
    }
 }
 ```
 ## Persistent Cache
 The cache system prevents false notifications:
 - **Automatic saving** - Saves when service status changes
 - **Persistent storage** - Maintains state across agent restarts
 - **Simple design** - No complex TTL or cleanup logic
 - **Status preservation** - Prevents duplicate notifications

 # TODO
 ## Systemd filtering (agent)
 - remove user systemd collection
 - reduce number of systemctl call
 - Cahnge so only services in include list are detected
 - Filter on exact name
 - Add support for "\*" in filtering
 ## System panel (agent/dashboard)
 use following layout:
 '''
 NixOS:
 Build: xxxxxx
 Agen: xxxxxx
 CPU:
 ● Load: 0.02 0.31 0.86
 └─ Freq: 3000MHz
 RAM:
 ● Usage: 33% 2.6GB/7.6GB  
 └─ ● /tmp: 0% 0B/2.0GB
 Storage:
 ● /:  
 ├─ ● nvme0n1 T: 40C • W: 4%  
 └─ ● 8% 75.0GB/906.2GB
 '''
 - Add support to show login/active users
 - Add support to show timestamp/version for latest nixos rebuild
 ## Backup panel (dashboard)
 use following layout:
 '''
 Latest backup:  
 ● <timestamp>
 └─ Duration: 1.3m
 Disk:
 ● Samsung SSD 870 QVO 1TB  
 ├─ S/N: S5RRNF0W800639Y

 # Hardcoded Values Removed - Configuration Summary
 ## ✅ All Hardcoded Values Converted to Configuration
 ### **1. SystemD Nginx Check Interval**
 - **Before**: `nginx_check_interval_seconds: 30` (hardcoded)
 - **After**: `nginx_check_interval_seconds: config.nginx_check_interval_seconds`
 - **NixOS Config**: `nginx_check_interval_seconds = 30;`
 ### **2. ZMQ Transmission Interval**  
 - **Before**: `Duration::from_secs(1)` (hardcoded)
 - **After**: `Duration::from_secs(self.config.zmq.transmission_interval_seconds)`
 - **NixOS Config**: `transmission_interval_seconds = 1;`
 ### **3. HTTP Timeouts in SystemD Collector**
 - **Before**: 
  ```rust
  .timeout(Duration::from_secs(10))
  .connect_timeout(Duration::from_secs(10))
  ```
 - **After**:
  ```rust
  .timeout(Duration::from_secs(self.config.http_timeout_seconds))
  .connect_timeout(Duration::from_secs(self.config.http_connect_timeout_seconds))
  ```
 - **NixOS Config**: 
  ```nix
  http_timeout_seconds = 10;
  http_connect_timeout_seconds = 10;
  ```
 ## **Configuration Structure Changes**
 ### **SystemdConfig** (agent/src/config/mod.rs)
 ```rust
 pub struct SystemdConfig {
    // ... existing fields ...
    pub nginx_check_interval_seconds: u64,      // NEW
    pub http_timeout_seconds: u64,              // NEW
    pub http_connect_timeout_seconds: u64,      // NEW
 }
 ```
 ### **ZmqConfig** (agent/src/config/mod.rs)
 ```rust
 pub struct ZmqConfig {
    // ... existing fields ...
    pub transmission_interval_seconds: u64,     // NEW
 }
 ```
 ## **NixOS Configuration Updates**
 ### **ZMQ Section** (hosts/common/cm-dashboard.nix)
 ```nix
 zmq = {
  # ... existing fields ...
  transmission_interval_seconds = 1;           # NEW
 };
 ```
 ### **SystemD Section** (hosts/common/cm-dashboard.nix)
 ```nix
 systemd = {
  # ... existing fields ...
  nginx_check_interval_seconds = 30;           # NEW  
  http_timeout_seconds = 10;                   # NEW
  http_connect_timeout_seconds = 10;           # NEW
 };
 ```
 ## **Benefits**
 ✅ **No hardcoded values** - All timing/timeout values configurable  
 ✅ **Consistent configuration** - Everything follows NixOS config pattern  
 ✅ **Environment-specific tuning** - Can adjust timeouts per deployment  
 ✅ **Maintainability** - No magic numbers scattered in code  
 ✅ **Testing flexibility** - Can configure different values for testing  
 ## **Runtime Behavior**
 All previously hardcoded values now respect configuration:
 - **Nginx latency checks**: Every 30s (configurable)
 - **ZMQ transmission**: Every 1s (configurable)  
 - **HTTP requests**: 10s timeout (configurable)
 - **HTTP connections**: 10s timeout (configurable)
 The codebase is now **100% configuration-driven** with no hardcoded timing values.

Christoffer Martinsson	bd20f0cae1	Fix user-stopped flag timing and service transition handling All checks were successful Build and Release / build-and-release (push) Successful in 2m9s Details Correct user-stopped service behavior during startup transitions: User-Stopped Flag Timing Fix: - Clear user-stopped flag only when service actually becomes active, not when start command succeeds - Remove premature flag clearing from service control handler - Add automatic flag clearing when service status metrics show active state - Services retain user-stopped status during activating/transitioning states Service Transition Handling: - User-stopped services in activating state now report Status::OK instead of Status::Pending - Prevents host warnings during legitimate service startup transitions - Maintains accurate status reporting throughout service lifecycle - Failed service starts preserve user-stopped flags correctly Journalctl Popup Fix: - Fix terminal corruption when using J key for service logs - Correct command quoting to prevent tmux popup interference - Stable popup display without dashboard interface corruption Result: Clean service startup experience with no false warnings and proper user-stopped tracking throughout the entire service lifecycle. Bump version to v0.1.47	2025-10-30 12:05:54 +01:00

Christoffer Martinsson	aeae60146d	Fix user-stopped service display and flag timing issues All checks were successful Build and Release / build-and-release (push) Successful in 2m10s Details Improve user-stopped service tracking behavior: Service Display Fix: - Services widget now shows actual systemctl status (active/inactive) - Use info.status instead of hardcoded text based on widget_status - User-stopped services correctly display 'inactive' with green OK icon - Prevents misleading 'active' display for stopped services User-Stopped Flag Timing Fix: - Clear user-stopped flag AFTER successful service start, not when command sent - Prevents warnings during service startup transition period - Service remains Status::OK during 'activating' state for user-stopped services - Flag only cleared when systemctl start command actually succeeds - Failed start attempts preserve user-stopped flag Result: Clean service state tracking with accurate display and no false alerts during intentional user operations.

Christoffer Martinsson	a82c81e8e3	Fix service control by adding .service suffix to systemctl commands All checks were successful Build and Release / build-and-release (push) Successful in 2m8s Details Service stop/start operations were failing because systemctl commands were missing the .service suffix. This caused the new user-stopped tracking feature to mark services but not actually control them. Changes: - Add .service suffix to systemctl commands in service control handler - Matches pattern used throughout systemd collector - Fixes service start/stop functionality via dashboard Clean up legacy documentation: - Remove outdated TODO.md, AGENTS.md, and test files - Update CLAUDE.md with current architecture and rules only - Comprehensive README.md rewrite with technical documentation - Document user-stopped service tracking feature Bump version to v0.1.44	2025-10-30 11:00:36 +01:00
Christoffer Martinsson	c56e9d7be2	Implement user-stopped service tracking system All checks were successful Build and Release / build-and-release (push) Successful in 2m34s Details Add comprehensive tracking for services stopped via dashboard to prevent false alerts when users intentionally stop services. Features: - User-stopped services report Status::Ok instead of Warning - Persistent storage survives agent restarts - Dashboard sends UserStart/UserStop commands - Agent tracks and syncs user-stopped state globally - Systemd collector respects user-stopped flags Implementation: - New service_tracker module with persistent JSON storage - Enhanced ServiceAction enum with UserStart/UserStop variants - Global singleton tracker accessible by collectors - Service status logic updated to check user-stopped flag - Dashboard version now uses CARGO_PKG_VERSION automatically Bump version to v0.1.43	2025-10-30 10:42:56 +01:00
Christoffer Martinsson	c8f800a1e5	Implement git commit hash tracking for build display All checks were successful Build and Release / build-and-release (push) Successful in 1m24s Details - Add get_git_commit() method to read /var/lib/cm-dashboard/git-commit - Replace NixOS build version with actual git commit hash - Show deployed commit hash as 'Build:' value for accurate tracking - Enable verification of which exact commit is deployed per host - Update version to 0.1.42	2025-10-29 15:29:02 +01:00
