Maintenance windows
Maintenance windows disable checks for a selected period so planned work does not produce false alerts.
When to use
- Server or database maintenance in night windows.
- Planned migrations with expected short availability gaps.
- Testing on temporarily unavailable infrastructure.
How to fill in
| Field | Value |
|---|---|
| Name | Use a short readable name to find the rule quickly. |
| Type | Single, daily, weekly or monthly schedule. |
| Time zone | Optional: in which time zone the schedule is calculated. |
| Date/time | Fields are different per type: exact date for one-time windows, time settings for recurring ones. |
| Duration | How long checks are considered disabled for this rule. |
| Tasks | Set of checks for which alerts will not be generated during maintenance. |
Note: if a task is inside a maintenance window, alerts for downtime are not sent during this period.
After maintenance ends, checks return to normal schedule.
Useful reminders
- Prefer exact start times and a small safety margin for one-time windows.
- For recurring maintenance, create a dedicated rule and review all affected tasks before enabling it.
