8.2.1 Events

An event is a significant occurrence that indicates a potential problem. When a metric threshold value is reached, a metric alert is raised. A metric alert is a type of event. An alert can also be generated for various target availability states.

Event Types

Typically, key event types used in Enterprise Monitoring are:

• Metric Alert: A metric alert event is generated when an alert occurs for a metric on a specific target or metric on a target and object combination, such as Lag Exceeding a Specified Threshold Value.
• Target Availability: The Target Availability Event represents a target's availability status. For example: Up, Down, Agent Unreachable, or Blackout. For more information on all the targets available in Oracle GoldenGate, see Supported Target Types.
