Here is my logstash configuration that I am using on Linux system.

input  
{  
file{  
codec =\> json  
path =\> "/home/admin/ELK\_Demo/demo.txt"  
stat\_interval =\> 5  
start\_position =\> "end"  
}  
}  
filter{  
json{  
source=\> "message"  
}  
}  
output  
{  
elasticsearch  
{  
hosts =\> "localhost:9200"   
}  
stdout  
{  
codec =\> rubydebug  
}  
}

The following is the data that I am having in my log file (demo.txt) .  
{ "name": "Maruti", "color": "Blue", "price": 10000, "sold": "2014-02-26"}  
{ "name": "Suzuki", "color": "Red", "price": 18000, "sold": "2014-04-18"}

Whenever I am getting some new log data, the logstash is sending the same data multiple times.

Please have a look and let me know if I am doing any mistake.

Thanks!
