You can configure blackouts to stop monitoring or alerting at specific periods, for example, when your web application is undergoing scheduled maintenance. This way, the maintenance time will not affect your application’s availability and performance data in AlertSite. Blackouts can be one-time or repeating every week.
You must be an Admin, Co-Admin or Power user to add or change monitor blackouts.
Alerting blackouts affect only availability alerts, like HTTP errors or timeouts. Performance alerts are sent during blackout periods as well.
We recommend that you add blackouts at least an hour before the blackout scheduled time. This will allow the changes to reach through our network of locations.
If a monitor has a blackout configured, it has the icon on a Dashboard tile. In the list view, such monitors have the icon for one-time blackouts and – for persistent ones in the Settings column. Hover over the icons to see what blackout type is enabled for the selected monitor.
Monitor blackouts also appear on the calendar in the Monitor Summary dashboard. To view or change them:
Go to Monitors > Summary.
Select the monitor from the drop-down list at the top.
One-time blackouts appear in dark gray. Recurring blackouts appear in blue.
In the Monitor Blackouts calendar, click Schedule Monitor Blackout.
Choose whether you want a one-time or recurring blackout and click Next.
Under Blackout Type, choose whether to disable monitoring completely, or only notifications (that is, the monitor still runs, but does not send alerts).
For one-time blackouts, set the start and end time.
For recurring blackouts, select the starting day of the week and start time, then the ending day of the week and the end time. The blackout occurs weekly on this schedule.
On the Dashboard, click the wrench icon next to the monitor you want to edit.
Click Blackouts to display the Monitor Blackouts screen.
The Monitor Blackouts screen has two sections:
Persistent Blackouts – Disable monitoring or error notifications for specified days and hours on a weekly basis. This is most useful when you have scheduled maintenance periods and want to temporarily halt monitoring during that time frame, or if you have recipients that you do not want to get alerts during certain times of the day or during weekends.
One-Time Blackouts – Used when you have a single event during which you do not want monitoring or notifications to take place.
Specify the blackout settings of the needed blackout type.
For persistent blackouts, select the starting day of the week and start time, then the ending day of the week and the end time. You need to also choose whether to disable monitoring completely, or only notifications (that is, the monitor still runs, but does not send alerts).
For example, you do not want to receive alerts from 6:00 PM on Friday through 7:00 AM on Monday.
Under Blackout From, select Friday from the Day drop-down list, enter 6:00 in the HH:MM, and select PM from the AM/PM drop-down list.
Under Blackout Thru, select Monday in Day, enter 7:00 in HH:MM, and select AM in AM/PM.
Click the radio button next to Disable all notifications for this monitor during the selected period(s).
For one-time blackout, set the start and end time.
For example, you scheduled an upgrade of your web server’s memory board for a specific date at 6 PM. It will take about 30 minutes, and you want to stop monitoring during that time.
In the One-Time Blackouts section, enter the date and time in YYYY-MM-DD HH:MM (24-hr clock) format in the From and To fields, or click on the calendar widget to the right of each field and select the date and click or drag to set the time.
Make sure to select monitoring in the Type drop-down list.
Click Add new one-time blackout.
The one-time blackout will be displayed at the bottom of the screen.
Click Submit to confirm.
You can use the bulk editor to add or change blackouts for multiple monitors at once. See Bulk Editing for details.
To change the blackout days or time:
In AlertSite UXM, click the blackout on the calendar and set a new period.

|You can edit only recurring blackouts. To change a one-time blackout, delete it and add a new one.|
On the blackout calendar, click the blackout. The Edit Blackout dialog appears.
Click Delete in the lower left corner, and then Yes to confirm.
On the Dashboard, click the clock icon next to the monitor name.
