Viewing and canceling Downtime

Overview of Schedule Downtime View

To get an overview of the downtimes whether scheduled, active, or historical, go to the Monitoring > Scheduled Downtimes page.

Viewing Downtimes

By default, the page displays the 'Live View' which summarizes ongoing downtimes and downtimes to come:


Once the downtime period is over, or if you have cancelled a downtime, the record is moved to the 'Historical View'.


Both 'Live View' and 'Historical View' have the following information available in the columns.

  • Start Time: The date/timestamp of the beginning of the downtime period.
  • Scheduled End Time: The date/timestamp of the scheduled end of the downtime period.
  • Duration: The duration of the downtime - between the start time and the current time.
  • Comment: When downtime is scheduled, users must enter a comment to describe it. This will be displayed here. This column can be filtered using the grid header menu to search for a specific string inside comments.
  • Objects: The total number of Host + Service Checks affected by this downtime. Clicking on this value provides the list of Hosts and Services Checks affected.
  • User: The user who scheduled this downtime. This column can be filtered using the grid header menu to search for a specific string inside usernames.

In addition, the 'Historical View' displays:

  • End Time: The timestamp of the actual end time of the downtime period.

If you wish to cancel all the scheduled downtimes at once, use the 'Cancel All' button in the top right corner of the page:
