(1) Any significant change in the state of a system resource, as represented in a Common Base Event. An event can be generated for a situation, such as a problem, the resolution of a problem, or the successful completion of a task. See also Common Base Event.
(2) A set of conditions that, when met, creates an event. A condition consists of an agent attribute, an operator such as greater than or equal to, and a value. It can be read as, "If - system condition - compared to - value - is true". An example of a situation is: IF - CPU usage - GT - 90% - TRUE. "IF" and "TRUE" are part of every situation. The expression "CPU usage GT 90%" is the situation condition.
(3) A significant occurrence that is detected when a set of conditions are met. For example, exceeding the limits of a Key Performance Indicator (KPI).
