[SOLVED] Average of a sum


(Alex Lum) #1

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:

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.
