Implement disk quota/total display in services widget showing usage/quota
format. When services don't have specific disk quotas configured, use
system total disk capacity as the quota value.
Changes:
- Add disk_quota_gb field to ServiceData struct in agent
- Add disk_quota_gb field to ServiceInfo struct in dashboard
- Update format_disk_value to show usage/quota format
- Use system disk total capacity as default quota for services
- Rename DiskUsage.total_gb to total_capacity_gb for clarity
Services will now display disk usage as "5.2/500.0 GB" format where
500.0 GB is either the service's specific quota or system total capacity.
Temporarily disable excessive connection monitoring in ServiceCollector
to test impact on CPU load and C-states. Keep nginx sites and docker
containers as they are needed for sub-service display functionality.
Disabled monitoring:
- SSH connections (ss commands)
- Database connections (PostgreSQL, MySQL, Redis)
- Web service connections (Apache, Gitea, Immich, etc.)
- Network service connections (Mosquitto, UniFi, etc.)
This eliminates most external command calls while preserving essential
nginx and docker sub-service enumeration.
- Add DEFAULT_HOSTS constant in config.rs for centralized host management
- Update ZMQ endpoint generation to connect to all configured hosts
- Implement graceful connection handling for unreachable endpoints
- Dashboard now auto-discovers and connects to available agents on cmbox, labbox, simonbox, steambox, srv01
- Fix systemctl, du, df, uptime, ss, journalctl commands
- Add sudo for du command (needed for directory access)
- This should resolve all remaining command path issues in the service
- Storage, backup, and system monitoring should now work properly
- Use full path /run/current-system/sw/bin/ss for SSH connection counting
- Re-enable nginx site accessibility checking with full curl path
- This should show SSH connection counts and verify which nginx sites are accessible
- Shows all parsed nginx sites instead of filtering by accessibility
- This ensures nginx sites are displayed in dashboard immediately
- Accessibility check was filtering out sites due to curl issues or timeouts
- Change nginx command from 'nginx' to '/run/current-system/sw/bin/nginx'
- Change psql command from 'psql' to '/run/current-system/sw/bin/psql'
- This ensures sudo rules can properly match the commands with full paths
Improve parsing of nginx config path from systemd ExecStart to handle
both traditional format and NixOS argv[] format. This should fix nginx
sites not being detected when running as a systemd service.
- Storage widget: Restructure with Name/Temp/Wear/Usage columns, SMART details as descriptions
- Host navigation: Only cycle through connected hosts, no disconnected hosts
- Auto-discovery: Skip config files, use predefined CMTEC host list
- Maintenance mode: Suppress notifications during backup via /tmp/cm-maintenance file
- CPU thresholds: Update to warning ≥9.0, critical ≥10.0 for production use
- Agent-dashboard separation: Agent provides descriptions, dashboard displays only
- Rename alerts widget to hosts widget for clarity
- Add sub_service field to ServiceInfo for display differentiation
- Integrate system metrics (CPU load, memory, temperature, disk) as service rows
- Convert nginx sites to individual sub-service rows with tree structure
- Remove nginx site checkmarks - status now shown via row indicators
- Update dashboard layout to display system and service data together
- Maintain description lines for connection counts and service details
Services widget now shows:
- System metrics as regular service rows with status
- Nginx sites as sub-services with ├─/└─ tree formatting
- Regular services with full resource data and descriptions
- Unified status indication across all row types
Agent Changes:
• Add CPU status thresholds (warning: ≥5.0, critical: ≥8.0)
• Add memory status thresholds (warning: ≥80%, critical: ≥95%)
• Add service status calculation (critical if failed>0, warning if degraded>0)
• All collectors now calculate and include status in output
Dashboard Changes:
• Update system widget to use agent-calculated cpu_status and memory_status
• Update services widget to use agent-calculated services_status
• Remove client-side status calculations in favor of agent status
• Add status_level_from_agent_status helper function
Notification System:
• Add SMTP email notification system using lettre crate
• Auto-configure notifications: hostname@cmtec.se → cm@cmtec.se
• Smart change detection with rate limiting (30min cooldown)
• Only notify on transitions to/from warning/critical states
• Rich email formatting with host, component, metric details
