I still dont understand what exactly you want to change.

Could you please be explicit ?

I have this input  
input {  
file {  
path =\> "/home/ec2-user/xxxxx/testservice.log"  
start\_position =\> "beginning"  
sincedb\_path =\> "/dev/null"  
}  
}

Try this :

```
input {
file {
path => "/home/ec2-user/xxxxx/testservice2.log"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}

```
