Flume regex extractor interceptor

Hi All,

Will flume regex extractor interceptor be applied on flume even header
values also or only the body?

Can i use it to extract a substring out of the fileHeader value in the
event header?

Thanks,
Jyotsna

Thank you so much.

Implemented a custom interceptor as suggested.

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.
