Hello, In visualization, data table , i have a sum of received mega octet. I need to make an average of this sum Total sessions Total received Mo Total sent Mo 3,233,566 810,058.816 1,070,446.362 can i have a column "average" like this : total received Mo divided by time range selected in up right? thanks. ---

You should just be able to add an Average Metric on the same field you're using to for the Sum of _Total received Mo_, no? Something like this: ![](https://us1.discourse-cdn.com/elastic/original/2X/7/7ab49d0cea525a6c4d3b30d8ab5620b30798781a.png) Here I have the count of requests, the total sum of bytes, and the average bytes per request. Is that what you're asking for, or am I misunderstanding? ---

I'm trying to do a very similar thing, but can't seem to make it work. (PEBKAC, I'm sure) How exactly do I make a column that is a sum divided by time range up right? For example, I have one column that is a top 10 by bytes transferred. I want to display the mbit/sec for the host beside it. I can pre-do some of the math in logstash via ruby if necessary (bytes to bits, etc) but I can't figure out how to take the value and divide it by whatever time is picked. I don't really want the average - there may be hundreds of thousands of packets, so the average size in bytes isn't what I want. I want to make a bytes/time column, where /time is based on the number of seconds in the time picker. ---
