To snooze one or more alerts:

  1. Check the check boxes next to the desired alert(s).
    • To snooze the alerts, click the Snooze dropdown, select the desired duration, and click OK.
    • To unsnooze the alerts, click Snooze > Unsnooze.

To snooze or unsnooze a single alert:

  • Select Snooze > <Duration> at the far left of the alert to snooze it.
  • Select Snooze > Unsnooze at the far left of the alert to unsnooze it.

Using Maintenance Windows

A maintenance window defines a time window when disruptive operations occur as a result of system maintenance or testing. During such operations, it’s likely that alerts will fire. You can create a maintenance window to prevent alerts from firing.

You can close (end) maintenance windows early or you can make them longer.

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