Prevent unnecessary notifications during scheduled maintenance windows.
During planned maintenance, it’s often helpful to suppress internal alerts that would otherwise be triggered by expected downtime. Upstat allows you to suppress monitor alerts during the defined maintenance window to reduce noise and avoid alert fatigue.
How Alert Suppression Works
When alert suppression is enabled on a maintenance event:
- Alerts from monitors linked to the affected catalog entities will be ignored during the maintenance window
- No alerts will be sent for failures that occur within the scheduled time range
- Monitoring data is still collected, but alerting systems will treat the downtime as expected
This ensures that on-call responders and internal teams are not notified for disruptions caused by known, intentional work.
Enabling Alert Suppression
When creating or editing a maintenance event, you can enable alert suppression:
- In the New Maintenance Event dialog, select the Suppress Alerts option
- Select which catalog entities or monitors should have alert suppression applied
- Save the maintenance event
Suppression will begin automatically at the defined start time and stop when the maintenance ends or is manually completed.
Considerations
- Suppression only applies to alerts—not to monitoring data itself
- If suppression is disabled, alerts may still fire during maintenance
- If a monitor is not linked to a catalog entity included in the maintenance event, it will not be suppressed
- Automations triggered by alerts will also be skipped if suppression is active
Use suppression carefully to avoid missing alerts for unrelated monitors.
Summary
- Suppressing alerts during maintenance avoids unnecessary notifications
- Alerts are paused for linked monitors during the maintenance window
- Suppression is optional and configured per maintenance event
- Monitoring continues in the background, but alerts are held back
