- Use actual device names (sdb, sdc) instead of data_0, parity_0
- Fix physical drive naming to show device names instead of mount points
- Update pool name extraction to handle new device-based naming

- Add mount_point metric parsing to use actual mount paths
- Fix pool consolidation to prevent duplicate entries
Add support for numeric mergerfs references like "1:2" by mapping them
to actual mount points (/mnt/disk1, /mnt/disk2). This enables proper
mergerfs pool detection and hides individual member drives as intended.
Skip mergerfs pools with numeric device references (e.g., "1:2")
instead of crashing. This allows regular drive detection to work
even when mergerfs uses non-standard mount formats.
Preserves existing functionality for standard mergerfs setups.
1. Add missing _fs_ filter to usage_percent parsing in dashboard
2. Fix agent to use calculated fs_status instead of hardcoded Status::Ok
This completes the disk collector auto-discovery by ensuring filesystem
usage percentages and status indicators display correctly.
Remove unused debug code and fix device name parsing to properly
handle lsblk tree characters. This resolves the issue where only
/boot filesystem was discovered instead of both /boot and /.
Add debug logging to filesystem usage collection to identify why
some mount points are being dropped during discovery. This should
resolve the issue where total capacity shows incorrect values.
Replaced complex disk collector with simple lsblk → df → group workflow.
Supports both physical drives and mergerfs pools with unified metrics.
Eliminates configuration complexity through pure auto-discovery.
- Clean discovery pipeline using lsblk and df commands
- Physical drive grouping with filesystem children
- MergerFS pool detection with parity heuristics
- Unified metric generation for consistent dashboard display
- SMART data collection for temperature, wear, and health
Updated filesystem grouping to use extract_base_device method for proper
partition-to-drive mapping. This ensures nvme0n1p1 and nvme0n1p2 are
correctly grouped under nvme0n1 drive pool instead of separate pools.
- Implement filesystem children display under physical drive pools

- Agent now assigns Status::Inactive instead of Status::Warning for inactive services
- Dashboard displays inactive services with empty circle (○) icon in gray color
- User-stopped services still show as Status::Ok with green filled circle
- Inactive services treated as OK for host status aggregation
- Improves visual clarity between active (●), inactive (○), and warning (◐) states
- Remove all transitional icon infrastructure (CommandType, pending transitions)
- Clean up ZMQ command system remnants after SSH migration
- Add real-time log streaming for service start operations
- Show final logs and status for service stop operations
- Fix compilation warnings by removing unused methods
- Simplify UI architecture with pure SSH-based service control
Replace ZMQ-based service start/stop commands with SSH execution in tmux
popups. This provides better user feedback with real-time systemctl output
while eliminating blocking operations from the main message processing loop.
Changes:
- Service start/stop now use SSH with progress display
- Added backup functionality with 'B' key
- Preserved transitional icons (↑/↓) for immediate visual feedback
- Removed all ZMQ service control commands and handlers
- Updated configuration to include backup_alias setting
- All operations (rebuild, backup, services) now use consistent SSH interface
This ensures stable heartbeat processing while providing superior user
experience with live command output and service status feedback.
Simplifies host connection configuration by removing tailscale_ip field,
connection_type preferences, and fallback retry logic. Now uses only the
ip field or hostname as fallback. Eliminates blocking TCP connectivity
tests that interfered with heartbeat processing.
This resolves intermittent host lost/found issues by removing the
connection retry timeouts that blocked the ZMQ message processing loop.
Implement maintenance_mode_file configuration option in NotificationConfig
to allow customizable file paths for suppressing email notifications.
Updates maintenance mode check to use configured path instead of hardcoded
/tmp/cm-maintenance file.

- Bump version to 0.1.56
- Add Status::Offline enum variant for disconnected hosts
- All configured hosts now always visible showing offline status when disconnected
- Add WakeOnLAN support using wake-on-lan Rust crate
- Implement w key binding to wake offline hosts with MAC addresses
- Simplify configuration to single [hosts] section with MAC addresses only
- Change critical status icon from ◯ to ! for better visibility
- Add proper MAC address parsing and error handling
- Silent WakeOnLAN operation with logging for success/failure
Configuration format:
[hosts]
hostname = { mac_address = "AA:BB:CC:DD:EE:FF" }
Fix notification issues for better operational experience:
Startup Notification Suppression:
- Suppress notifications for transitions from Status::Unknown during agent/server startup
- Prevents notification spam when services transition from Unknown to Warning/Critical on restart
- Only real status changes (not initial discovery) trigger notifications
- Maintains alerting for actual service state changes after startup
Recovery Notification Refinement:
- Recovery notifications only sent when ALL services reach OK status
- Individual service recoveries suppressed if other services still have problems
- Ensures recovery notifications indicate complete system health restoration
- Prevents premature celebration when partial recoveries occur
Result: Clean startup experience without false alerts and meaningful recovery
notifications that truly indicate full system health restoration.
Bump version to v0.1.48
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
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.
Bump version to v0.1.45
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:

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
- 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
- Replace hardcoded 500ms/2000ms thresholds with configurable nginx_latency_critical_ms
- Simplify status logic to only OK or Critical (no Warning status)
- Add validation for nginx latency threshold configuration
- Re-enable nginx site collection with configurable thresholds
- Resolves issue where sites showed critical at 2000ms despite 30s timeout setting
- Bump version to v0.1.38
Enhanced service discovery to properly show status for all services:
Changes:
- Use systemctl list-unit-files for complete service discovery (finds all services)
- Use systemctl list-units --all for batch runtime status fetching
- Combine both datasets to get comprehensive service list with correct status
- Services found in unit-files but not runtime are marked as inactive (Warning status)
- Eliminates 'unknown' status issue while maintaining complete service visibility
Now inactive services show as Warning (yellow ◐) and active services show as Ok (green ●)
instead of all services showing as unknown (? icon).
Changed service discovery from 'systemctl list-units --all' to 'systemctl list-unit-files'
to ensure ALL service unit files are discovered, including services that have never been started.
Changes:
- Updated systemctl command to use list-unit-files instead of list-units --all
- Modified parsing logic to handle unit file format (2 fields vs 4 fields)
- Set placeholder values in discovery cache, actual runtime status fetched during collection
- This ensures all configured services (like inactive ARK servers) appear in dashboard
The issue was that list-units --all only shows services systemd has loaded/attempted to load,
but list-unit-files shows ALL service unit files regardless of their runtime state.
Simplified keyboard controls by removing service restart functionality:
- Removed 'r' key restart functionality from Services panel
- Made 'R' key always trigger system rebuild regardless of focused panel
- Updated context shortcuts to show 'R: Rebuild Host' globally
- Removed all ServiceRestart enum variants and associated code:
- UiCommand::ServiceRestart
- CommandType::ServiceRestart
- ServiceAction::Restart
- Cleaned up pending transition logic to only handle Start/Stop commands
The 'R' key now consistently rebuilds the current host from any panel,
while 's' and 'S' continue to handle service start/stop in Services panel.
