Hi,  
i created a logStash filter to pickup the data from a file.  
The file has almost 20K entries.  
I tested the filter on the - [http://grokdebug.herokuapp.com/](http://grokdebug.herokuapp.com/)  
The output seems to be fine but when i check elastisearch, I see only 3 rows.  
I am not sure whether the complete data was not passed onto elasticsearch or whether I am not checking correctly  
I am not sure where to start looking.

Is there any log file within logstash or elasticsearch which will tell me how many entries were pushed into elasticsearch.
