I am looking something like the following result
I know delta command will give the difference but is there any command which gives the aggregation
I got it there is command called accum
http://docs.splunk.com/Documentation/Splunk/latest/SearchReference/Accum
You should check out addcoltotals
It will work like this | addcoltotals labelfield=change_name label=ALL
http://docs.splunk.com/Documentation/Splunk/7.0.1/SearchReference/Addcoltotals
I know about addcoltotals,but that does not do something like a delta where For each event where field is a number, the delta command computes the difference, in search order, between the field value for the event and the field value for the previous event. The delta command writes this difference into newfield.
In the similar manner instead of difference I am looking for addition of it
