When I copied (Ctrl +C, Ctrl +V) the new records(two times new records) in .csv (Which is my input file), logstash read the changes along with old records.  
First time insert of records:- I added 50 records, everything looks good.  
Second time insert of records:- I added 151 records, On Discovery I can see 251 records instead 151. Kibana still replicated with initial 50 records.  
Third time insert of records :- I added 100 more records, ON Discovery I can see 756 records. Kibana shows only 251 records.

Seems like I missed some setting.

//MY Logstash input.

```
input {
  file {
    path => "C:\Users\1480587\Documents\Chander\Elastic\Data\Inc_Det.csv"
    start_position => "beginning"
    sincedb_path => "nul"
  }
}
```
