WSO2Event event publisher handles WSO2 events. It sends WSO2 events over Thrift using TCP, SSL/ TCP, HTTP, and HTTPS protocols to any external server, which can receive them.

Creating a WSO2Event event publisher

For instructions on creating a WSO2Event event publisher, see Configuring CEP to Create Alerts.

Configuring adapter properties

Specify the Static Adapter Properties, when creating a WSO2Event event publisher using the management console as shown below.

WSO2Event event publisher

After entering the above adapter properties, select the Event Stream to which you want to map the incoming events, and the Message Format which you want to apply on the receiving events. Also, click Advanced to define custom input mappings based on the Message Format you selected. For more information on custom input mapping types, see Input Mapping Types.

You can also define the respective adapter properties of the event receiver based on the transport type within the <from> element of the event receiver configuration in the <PRODUCT_HOME>/repository/deployment/server/eventreceivers/ directory as follows.
