Fix NFS export parsing to handle both inline and continuation formats

Support exportfs output where network info appears on same line as path
(e.g. /srv/media/tv 192.168.0.0/16(...)) in addition to continuation
line format. Ensures all NFS exports are detected correctly.

-**Agent hash display working correctly ✅**
 
-### Current Keyboard Navigation Implementation
+- **Direct Control**: Arrow keys (↑↓) or vim keys (j/k) navigate services
+- **Service Actions**:
+  - `s` - Start service (sends UserStart command)
+  - `S` - Stop service (sends UserStop command)
+  - `J` - Show service logs (journalctl in tmux popup)
+  - `L` - Show custom log files (tail -f custom paths in tmux popup)
+  - `R` - Rebuild current host
+- **Visual Status**: Green ● (active), Yellow ◐ (inactive), Red ◯ (failed)
+- **Transitional Icons**: Blue arrows during operations
 
-**Navigation Controls:**
+### Navigation
-- **Tab**: Switch between hosts (cmbox, srv01, srv02, steambox, etc.)
+
-- **Shift+Tab**: Cycle through visible panels (System → Services → Backup → System)
+- **Tab**: Switch between hosts
-- **Up/Down (System/Backup)**: Scroll through panel content
+- **↑↓ or j/k**: Select services
-- **Up/Down (Services)**: Move service selection cursor between parent services
+- **s**: Start selected service (UserStart)
+- **S**: Stop selected service (UserStop)
+- **J**: Show service logs (journalctl)
+- **L**: Show custom log files
+- **R**: Rebuild current host
+- **B**: Run backup on current host
 - **q**: Quit dashboard
 
-**Panel-Specific Features:**
+## Core Architecture Principles
-- **System Panel**: Scrollable content with CPU, RAM, Storage details
-- **Services Panel**: Service selection cursor for parent services only (docker, nginx, postgresql, etc.)
-- **Backup Panel**: Scrollable repository list with proper overflow handling
 
-**Visual Feedback:**
+### Structured Data Architecture (✅ IMPLEMENTED v0.1.131)
-- **Focused Panel**: Blue border and title highlighting
-- **Service Selection**: Blue background with preserved status icon colors (green ● for active, red ● for failed)
-- **Focus-Aware Selection**: Selection highlighting only visible when Services panel focused
-- **Dynamic Statusbar**: Context-aware shortcuts based on focused panel
 
-### Remote Command Execution - WORKING ✅
+Complete migration from string-based metrics to structured JSON data. Eliminates all string parsing bugs and provides type-safe data access.
 
-**All Issues Resolved (as of 2025-10-24):**
+**Previous (String Metrics):**
-- ✅ **ZMQ Command Protocol**: Extended with ServiceControl and SystemRebuild variants
-- ✅ **Agent Handlers**: systemctl and nixos-rebuild execution with maintenance mode
-- ✅ **Dashboard Integration**: Keyboard shortcuts execute commands
-- ✅ **Service Control**: Fixed toggle logic - replaced with separate 's' (start) and 'S' (stop)
-- ✅ **System Rebuild**: Fixed permission issues and sandboxing problems
-- ✅ **Git Clone Approach**: Implemented for nixos-rebuild to avoid directory permissions
-- ✅ **Visual Feedback**: Directional arrows for service status (↑ starting, ↓ stopping, ↻ restarting)
 
-**Keyboard Controls Status:**
+- ❌ Agent sent individual metrics with string names like `disk_nvme0n1_temperature`
-- **Services Panel**: 
+- ❌ Dashboard parsed metric names with underscore counting and string splitting
-  - R (restart) ✅ Working
+- ❌ Complex and error-prone metric filtering and extraction logic
-  - s (start) ✅ Working  
-  - S (stop) ✅ Working
-- **System Panel**: R (nixos-rebuild) ✅ Working with --option sandbox false
-- **Backup Panel**: B (trigger backup) ❓ Not implemented

-**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
-
-**NEW ARCHITECTURE**: Agent collects individual metrics, dashboard composes widgets from those metrics.
 
 ### 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
 # ... maintenance work ...
 systemctl start service

-**NixOS Integration:**
+## Development and Deployment Architecture
 
-- Borgbackup script automatically creates/removes maintenance file
+### Development Path
-- Automatic cleanup via trap ensures maintenance mode doesn't stick
-- All cinfiguration are shall be done from nixos config
 
-**ARCHITECTURE ENFORCEMENT**:
+- **Location:** `~/projects/cm-dashboard`
+- **Purpose:** Development workflow only - for committing new code
+- **Access:** Only for developers to commit changes
 
-- **ZERO legacy code reuse** - Fresh implementation following ARCHITECT.md exactly
+### Deployment Path
-- **Individual metrics only** - NO grouped metric structures
-- **Reference-only legacy** - Study old functionality, implement new architecture
-- **Clean slate mindset** - Build as if legacy codebase never existed
 
-**Implementation Rules**:
+- **Location:** `/var/lib/cm-dashboard/nixos-config`
+- **Purpose:** Production deployment only - agent clones/pulls from git
+- **Workflow:** git pull → `/var/lib/cm-dashboard/nixos-config` → nixos-rebuild
 
-1. **Individual Metrics**: Each metric is collected, transmitted, and stored individually
+### Git Flow
-2. **Agent Status Authority**: Agent calculates status for each metric using thresholds
-3. **Dashboard Composition**: Dashboard widgets subscribe to specific metrics by name
-4. **Status Aggregation**: Dashboard aggregates individual metric statuses for widget status
-   **Testing & Building**:
 
-- **Workspace builds**: `cargo build --workspace` for all testing
+```
-- **Clean compilation**: Remove `target/` between architecture changes
+Development: ~/projects/cm-dashboard → git commit → git push
-- **ZMQ testing**: Test agent-dashboard communication independently
+Deployment:  git pull → /var/lib/cm-dashboard/nixos-config → rebuild
-- **Widget testing**: Verify UI layout matches legacy appearance exactly

+## Automated Binary Release System
 
-- Copy/paste ANY code from legacy backup
+CM Dashboard uses automated binary releases instead of source builds.
-- Calculate status in dashboard widgets
-- Hardcode metric names in widgets (use const arrays)
 
-# Important Communication Guidelines
+### Creating New Releases
 
-NEVER write that you have "successfully implemented" something or generate extensive summary text without first verifying with the user that the implementation is correct. This wastes tokens. Keep responses concise.
+```bash
+cd ~/projects/cm-dashboard
+git tag v0.1.X
+git push origin v0.1.X
+```
 
-NEVER implement code without first getting explicit user agreement on the approach. Always ask for confirmation before proceeding with implementation.
+This automatically:
+
+- Builds static binaries with `RUSTFLAGS="-C target-feature=+crt-static"`
+- Creates GitHub-style release with tarball
+- Uploads binaries via Gitea API
+
+### NixOS Configuration Updates
+
+Edit `~/projects/nixosbox/hosts/services/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";
+};
+```
+
+### 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:"
+```
+
+### Building
+
+**Testing & Building:**
+
+- **Workspace builds**: `nix-shell -p openssl pkg-config --run "cargo build --workspace"`
+- **Clean compilation**: Remove `target/` between major changes
+
+## Enhanced Storage Pool Visualization
+
+### Auto-Discovery Architecture
+
+The dashboard uses automatic storage discovery to eliminate manual configuration complexity while providing intelligent storage pool grouping.
+
+### Discovery Process
+
+**At Agent Startup:**
+
+1. Parse `/proc/mounts` to identify all mounted filesystems
+2. Detect MergerFS pools by analyzing `fuse.mergerfs` mount sources
+3. Identify member disks and potential parity relationships via heuristics
+4. Store discovered storage topology for continuous monitoring
+5. Generate pool-aware metrics with hierarchical relationships
+
+**Continuous Monitoring:**
+
+- Use stored discovery data for efficient metric collection
+- Monitor individual drives for SMART data, temperature, wear
+- Calculate pool-level health based on member drive status
+- Generate enhanced metrics for dashboard visualization
+
+### Supported Storage Types
+
+**Single Disks:**
+
+- ext4, xfs, btrfs mounted directly
+- Individual drive monitoring with SMART data
+- Traditional single-disk display for root, boot, etc.
+
+**MergerFS Pools:**
+
+- Auto-detect from `/proc/mounts` fuse.mergerfs entries
+- Parse source paths to identify member disks (e.g., "/mnt/disk1:/mnt/disk2")
+- Heuristic parity disk detection (sequential device names, "parity" in path)
+- Pool health calculation (healthy/degraded/critical)
+- Hierarchical tree display with data/parity disk grouping
+
+**Future Extensions Ready:**
+
+- RAID arrays via `/proc/mdstat` parsing
+- ZFS pools via `zpool status` integration
+- LVM logical volumes via `lvs` discovery
+
+### Configuration
+
+```toml
+[collectors.disk]
+enabled = true
+auto_discover = true  # Default: true
+# Optional exclusions for special filesystems

-   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
+
+### Components

+```
+
+### 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%)
-  nginx: Warning → Critical
 
-🟡 WARNINGS (1):
+🟡 WARNINGS (2):
-  redis: Ok → Warning (memory usage 85%)
+  nginx: Ok → Warning (high load 8.5)
+  redis: user-stopped → Warning (restarted by system)
 
 ✅ RECOVERIES (0):
 
-🟢 SERVICE STARTUPS (15):
-  docker: Unknown → Ok
-  sshd: Unknown → Ok

-## 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
-
