the yellow mark is the data that i want to calculate the time. my logic is to grouping the data with session and calculate the time by (recent time - oldest time) or (top 1 CreateAt_descending - top 1 CreateAt_ascending) to calculate the session duration. is there any way to get this result.

Thanks.

You can create a custom field for calculating the time difference using the painless script. There is an example available at https://www.elastic.co/blog/using-painless-kibana-scripted-fields Hope it helps

Because am not so familiar with this language, it's so different from SQL.
