Alerts Histogram view
Use this view to create reports with simple graphs showing, for individual
hosts or services, number of events of different types over different time
periods.

shows, for example, two
CRITICAL events and three WARNING events occurred
around 6:45, and two recovery (
OK ) events occurred around 7:00.
