Maintenance Windows

Maintenance windows suppress alerts and modify automation autonomy during planned work. They prevent false-positive notifications when you are intentionally taking systems offline.

Creating a Maintenance Window

Navigate to Automations → Maintenance and click New Window.

Field	Description
Name	Display label (e.g. "Weekly NAS reboot")
Start	Date and time the window begins
End	Date and time the window ends
Recurring	Optional cron expression for repeating windows
Scope	Which monitors and agents the window applies to
Autonomy Override	Override agent autonomy level during the window

Alert Suppression

While a maintenance window is active:

• Monitors in scope show status Maintenance instead of Down.
• Alert rule evaluations still run, but notifications are not sent.
• The SLA calculation excludes the window duration (uptime is not penalised).
• Incidents are still created and logged but are tagged maintenance.

Autonomy Override

Set Autonomy Override to disabled to prevent any automations from running during the window (useful when a core system is offline). Set to execute to allow automations to run without approval gates (useful for automated maintenance tasks).

Activating a Window Early

Click Activate Now to start a window immediately, regardless of its scheduled start time.

Deactivating a Window

Click End Now to close an active window early. Monitors return to their normal evaluation state within the next check cycle.

Recurring Windows

Use a cron expression to create repeating maintenance windows:

Expression	Meaning
0 3 * * 0	Every Sunday at 03:00
0 2 1 * *	First day of every month at 02:00
30 1 * * 1-5	Weekdays at 01:30

The window duration is inferred from the original start/end times. For example, a window from 03:00 to 04:00 on a 0 3 * * 0 schedule will recur as a 1-hour window every Sunday.

Active Window Indicator

When a maintenance window is active, a banner appears at the top of the dashboard indicating which window is in effect and when it is scheduled to end.

Maintenance and Workflows

Link a maintenance window to a workflow using the Nightly Maintenance playbook template, which automatically:

1. Activates the window at the start of the workflow.
2. Performs the maintenance tasks.
3. Deactivates the window at the end.
4. Sends a completion report.

See Workflows for details.
