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.
