Scheduled & Smart Reboots for Managed Servers

Summary Introduce a flexible and intelligent reboot management system within Ploi, allowing users to schedule fixed server restarts or automatically reboot servers when required by system updates.

⸻

Key Features

1. Scheduled Restart (Cron-based)

• Allow users to configure fixed reboot schedules Support:
• Presets (e.g. daily at 01:00, weekly)
• Custom cron expressions (advanced users) Show:
• Next scheduled restart
• Last/next execution preview
• Safety confirmation before enabling unattended restarts

2. Auto-Restart When Required

• Automatically reboot servers only when required (e.g. kernel updates)
• Runs within a defined maintenance window
• Prevents unnecessary reboots while ensuring updates are applied

3. Maintenance Window Configuration

• Define preferred reboot window (e.g. Sunday 03:00) Used by:
• Auto-restart when required
• Future maintenance tasks (extensible)

⸻

UI / UX

• Central “Scheduled Maintenance” section per server Toggle-based controls:
• Scheduled Restart (On/Off)
• Auto-Restart When Required (On/Off)
• Clear schedule preview (human-readable + cron) Warning/acknowledgement for unattended restarts

⸻

Technical Considerations

• Use system-level scheduling (cron / systemd timers)
• Detect reboot requirement (e.g. /var/run/reboot-required)
• Ensure agent awareness (Ploi agent sync / health checks)
• Graceful reboot handling (optional pre-checks in future)

⸻

Value / Benefits

• Improves server stability and security (timely updates)
• Reduces manual maintenance workload
• Prevents downtime during peak hours
• Provides MSP-grade control over infrastructure lifecycle

⸻

Future Enhancements

• Pre-reboot hooks (stop services, notify users)
• Post-reboot health checks & alerts
• Cluster-aware rolling reboots
• Integration with monitoring/alerting
• Global policies (apply to multiple servers)
