Hey i am working on data visulization using kibana.  
So for that i am reading my log file using logstash but my problem is whenever i click on refresh button in kibana whole log file is read again. But i want to read the log file from the last read position that is i want to read the newely inserted records.

Need urgent help!!!!!!!!!!!!

I am attaching the code my config file below:

input{

```
 file{
     type => "log"
     path =>"/home/dummy.log"
     start_position =>"beginning"
     sincedb_path => "/dev/null"
     }

```

}

filter {

grok {  
match =\> [  
"message","(?[\d-]+)\s(?[\d:]+),(?[\w]+):(?[\w-/]+)"  
]  
}

}

output {  
elasticsearch {  
host =\> "localhost"  
index=\> "dummy"  
document\_type =\> "dummy\_sample"  
}

}

This means that the full file will be reread every time Logstash restarts.
