I need a litle a bit of help, i am a total newbie on ELK,

I want to add log to the same index every week, but i will get duplicate row in my output file, but i want only one occurence of each log.

What i am suppose to do ? I see some topics on figerprint bur i don't understand how to use it.

My csv format : [Site;alarmTime;swVersion;downtime]

> **My Filter :**

> filter {  
> csv {  
> separator =\> ";"  
> columns =\> [Site;alarmTime;swVersion;downtime]  
> }
