Hi Jyotsna, the Regex Extractor Interceptor reads only the event body and writes into the headers.
However, you can write custom interceptor easily by implementing this interface: https://github.com/apache/flume/blob/trunk/flume-ng-core/src/main/java/org/apache/flume/interceptor/Interceptor.java as you can see, you get the whole Event.
