Hi,  
I need some help and don't know how to start with it.

Basically, i have two csv input files (coming from 2 different nodes) and would like to sum the values with the result going to elasticsearch..

Any help is greatly appreciated...

CSV1  
node link rate-in rate-out  
node1 link1 10 20  
node1 link2 30 50  
node1 link3 40 60

CSV2  
node link rate-in rate-out  
node2 link1 20 10  
node2 link2 50 70  
node2 link3 80 40

Result --\> create elasticsearch index  
node link rate-in rate-out  
allnode link1 30 30  
allnode link2 80 120  
allnode link3 120 100

Thanks!

You could try using an [aggregate](https://www.elastic.co/guide/en/logstash/current/plugins-filters-aggregate.html) filter with the link as the task id.
