Learn how to use maintenance windows to prevent alerts from firing when systems are undergoing maintenance.

A maintenance window is a time window when disruptive operations occur as a result of system maintenance or testing. These disruptive operations create a high likelihood of causing alerts to fire. A maintenance window allows you to identify when maintenance is scheduled and prevent affected alerts from firing.

You can close (end) maintenance windows before they are due to end and you can extend the end time by various increments.

To view and manage maintenance windows, select Browse > Maintenance Windows.

Creating a Maintenance Window

  1. Click Alerts or Browse > Maintenance Windows.
  2. Click the Create Maintenance Window button located at the top of the filter bar.
