Hi all,
First of all, I posted via email but somehow I can't see it in
[groups.google.com](http://groups.google.com) so posting via web-ui.
I'm using ES to store maillogs. In that, I'm trying to use ES to generate
statistics for ex, per domain bandwidth usage etc.
For ex, if I have a document which has fields like:
- @fields.from: [abc@domain.com](mailto:abc@domain.com)
- @fields.size: 1024
Now, there can be many email addresses like [abc@domain.com](mailto:abc@domain.com). I just want the
summation of size for a particular domain. How do I accomplish that?
I had a look at statistical facet and scripts but I'm not sure how will I
use it to do per domain summation of @fields.size field. Ultimately, I want
something like: [domain.com](http://domain.com) did x size of mails.
Any help is highly appreciated. Thanks
