Creating custom Common Base Event content handlers

Create a custom Common Base Event content handler or template to automate configuration or values for specific events.

Before you begin

A content handler is an object that automatically sets the property values of each event based on any arbitrary policies that you want to use.

The following content handler classes were added to WebSphere® Application Server to facilitate the use of the Common Base Event infrastructure:

Class Name Description
WsContentHandlerImpl This provides an implementation of org.eclipse.hyades.logging.events.cbe.ContentHandler specifically for use in the WebSphere Application Server environment. This content handler completes Common Base Events using information from the WebSphere Application Server runtime, and it uses the same content handler as is used internally by the WebSphere Application Server when completing Common Base Events for logging.
WsTemplateContentHandlerImpl This provides the same function as WsContentHandlerImpl, but it extends the org.eclipse.hyades.logging.events.cbe.impl.TemplateContentHandlerImpl class to enable the use of a Common Base Event template. Template content takes precedence in cases where the template data specifies values for the same Common Base Event fields as does the WsContentHandlerImpl.

About this task

In some situations, you might want some event property data set automatically for every event that you create. This automation is a way to fill in certain standard values that do not change, such as the application name, or to set some properties based on information that is available from the runtime environment, like creation time or thread information. You can set property data automatically by creating a content handler.

Procedure

Results

You now have a content handler or a custom content handler template based on the settings that you specified.
