When working in a large enterprise, it is conceivable that when systems are under heavy load, a large number of incidents and events may be generated. All of these need to be processed in a timely and efficient manner in accordance with your business priorities. An effective prioritization scheme is needed to determine which events/incidents should be resolved first.

In order to determine which event/incidents are high priority, Enterprise Manager uses a prioritization protocol based on two incident/event attributes: Lifecycle Status of the target and the Incident/Event Type. Lifecycle Status is a target property that specifies a target's operational status. You can set/view a target's Lifecycle Status from the UI (from a target's Target Setup menu, select Properties). You can set target Lifecycle Status properties across multiple targets simultaneously by using the Enterprise Manager Command Line Interface (EM CLI) set_target_property_value verb.

A target's Lifecycle Status is set when it is added to Enterprise Manager for monitoring. At that time, you determine where in the prioritization hierarchy that target belongs—the highest level being "mission critical" and the lowest being "development."

Target Lifecycle Status

• Mission Critical (highest priority)

• Production

• Stage

• Test

• Development (lowest priority)

Incident/Event Type

• Availability events (highest priority)

• Non-informational events.

• Informational events
