Read source filename from beats and redirect output to different Elastic Search index

[pavanssetty]

I want to read the source of the csv data and redirect the output to a different ElasticSearch index.
I tried as below (if condition with source in output) by following various discussions but it did not work. It is always going to else part.

Here is my logstash config:

input {
	beats {
		port => "5044"
	}
}
filter {
	csv {
		autodetect_column_names => true
		separator => ","
		remove_field => ["message"]
	}
}

output {
	**if [source] == 'E:\\test_ingest\\test.csv'** {
		elasticsearch {
			hosts => "localhost:9200"
			manage_template => false
			index => "test_index"
			document_type => "nasuni_log"
		}
	} else {
              elasticsearch {
			hosts => "localhost:9200"
			manage_template => false
			index => "b_index"
			document_type => "nasuni_log"
		}
	}
}

The approach seems reasonable. What does one of the events look like? Copy and paste from the JSON tab in Kibana Discover.

Here is the input example from csv with header:

timestamp(UTC),category,event type,path/from,new path/to,user,group,sid,share/export name,volume type,client IP,snapshot timestamp(UTC),shared link
2018-04-12 12:16:57.846484,Write,Truncate File,/Design/CCH/t3est/review comments.docx,,EMEA\kandrgan,EMEA\domain users,S-1-5-21-1409082233-362288127-725345543-319468,Design,CIFS,10.123.3.58,,

Here is the json from Kibana:
I have only hidden the business related values

If that is what you see in Kibana then I believe this, with single backslashes, will compare true:

if [source] == 'E:\test_ingest\test.csv'
