I have 4 log files from 4 completely different applications  
For e.g. Log A, B, C, D

The log format of A AND B is same and  
The log format of A, C, and D is different

Source of reading log A, B and C is filebeat =\> Logstash  
And Source of reading D is UDP =\> Logstash

I want to create 4 different Indexes in ElasticSearch and would prefer to have 4 different pipelines to keep all the configuration separate

I'm not sure what you're asking.

> I want to create 4 different Indexes in Elasticsearch

Why? Keep in mind that all shards have a fixed memory overhead so splitting your indexes in too many pieces isn't free.

> and would prefer to have 4 different pipelines to keep all the configuration separate

Then just run four Logstash instances.

I/We need 4 different indexes as all 4 logs belongs to completely different applications  
and we dont prefer to run/maintain multiple instance of Logstash as of now.  
Thanks

In that case [http://stackoverflow.com/questions/27146032/make-logstash-add-different-inputs-to-different-indices](http://stackoverflow.com/questions/27146032/make-logstash-add-different-inputs-to-different-indices) should answer your question.
