The Access Gateway uses the Event Emitter mediation primitive provided with the base WebSphere® ESB platform for emitting Common Event Infrastructure (CEI) events.
To allow for enabling or disabling Event Emitter output through policies within the default flow, an additional filtering step has been added in front of the Event Emitter mediation primitive. This additional filtering step determines whether to emit the event. The policy configuration described in this topic applies only to the Access Gateway default flow.
For more information, refer to the topic Event Emitter mediation primitive in the WebSphere ESB information center.
This mediation primitive uses the following policy for runtime configuration:
message.cei.Enabled
