Title bar now only shows Critical (red), Warning (yellow), and OK (green)
colors. Pending status is ignored in color calculation to prevent blue
title bar during service transitions.
Replace separate service_logs_cmd with service-manage logs action
to unify service management through single script interface.
Dashboard now calls 'service-manage logs <service>' which provides
intelligent log viewing based on service state and configuration.

service_logs_cmd from dashboard config. Script handles both journalctl
and custom log files automatically based on service configuration.
Update status bar to show all available keybindings including
previously missing backup and terminal commands.

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.
Eliminates automatic CollectNow command sending on host connection which
was blocking the main message processing loop for up to 5 seconds per
command. Since agents transmit cached data every 2 seconds anyway, the
CollectNow optimization provided minimal benefit while causing heartbeat
detection issues. Also removes unused send_command wrapper method.
This should completely resolve intermittent host connection dropping.
Eliminates test_tcp_connectivity function that was causing 5-10 second
startup delays. ZMQ connections are non-blocking and we rely entirely
on heartbeat mechanism for connectivity detection. This restores fast
dashboard startup time.
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.
Update the auto connection type logic to try local network connections
before falling back to Tailscale. This provides better performance by
using faster local connections when available while maintaining Tailscale
as a reliable fallback.
Changes:
- Auto connection priority: local → tailscale → hostname (was tailscale → local)
- Fallback retry order updated to match new priority
- Supports omitting IP field in config for hosts without static local IP
Display the connection IP address that the dashboard is configured to use
for each host below the Agent version information. Shows which network
path (local/Tailscale) is being used for connections based on host
configuration.
Features:
- Display detected IP below Agent row in system widget
- Uses existing host configuration connection logic
- Shows actual IP being used for dashboard connections
Implement configurable network routing for both local and Tailscale networks.
Dashboard now supports intelligent connection selection with automatic fallback
between network types. Add IP configuration fields and connection routing logic
for ZMQ and SSH operations.
Features:
- Host configuration with local and Tailscale IP addresses
- Configurable connection types (local/tailscale/auto)
- Automatic fallback between network connections
- Updated ZMQ connection logic with retry support
- SSH command routing through configured IP addresses
Implement maintenance_mode_file configuration option in NotificationConfig
to allow customizable file paths for suppressing email notifications.

/tmp/cm-maintenance file.

Issue Resolution:
- Change tmux display-popup flag from -t to -T for setting popup title
- -t flag was incorrectly trying to target a session named 'Logs: servicename'
- -T flag correctly sets the popup window title
The J key (Shift+j) service logs feature now works properly, opening
an 80% tmux popup with journalctl -f for real-time log viewing.
Bump version to v0.1.49
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

Result: Clean startup experience without false alerts and meaningful recovery
notifications that truly indicate full system health restoration.
Bump version to v0.1.48
