Maintenances allow you to define time periods when systems will be unavailable for monitoring. During these maintenance windows, the monitoring connectors for affected systems are automatically placed in maintenance mode, preventing false alerts.

You can create three types of maintenance periods:

• 'Ad hoc' - Manually started and stopped maintenance windows with no schedule
• 'Scheduled' - One-time maintenance at a specific date and time
  • 'Not Recurrent' - One-time maintenance at a specific date and time
  • 'Recurrent' - Repeating maintenance windows (daily, weekly, or monthly patterns)
  • 'Custom CRON' - Advanced scheduling using quartz cron expressions

The maintenance settings page displays a table of all defined maintenance periods within the tenant.

The page includes:

• A 'Create' button to define new maintenance periods
• Bulk action buttons that appear when items are selected:
  • 'Enable selection' - Enable selected maintenance periods
  • 'Disable selection' - Disable selected maintenance periods
  • 'Start selection' - Manually start selected maintenance periods
  • 'Stop selection' - Manually stop selected maintenance periods
  • 'Delete selection' - Remove selected maintenance periods
  • 'Duplicate selection' - Copy selected maintenance periods
  • 'Export selection' - Export selected maintenance data
  • 'Test selection' - Test selected maintenance configurations
• A filter field to search maintenance periods by name
