Your custom vis should be very simple then. Take two Metric Aggs, and divide them, showing the result. No need for buckets.

I haven't written a custom vis before. I was hoping for something so basic that Kibana provided it. Javascript skills-permitting, I guess I can get my hands dirty. Any tutorials you recommend I read?

There is one tutorial around there, that I have used as a starting point:
> **[Writing Kibana 4 Plugins – Basics](https://www.timroes.de/2015/12/02/writing-kibana-4-plugins-basics/)**
>
> This tutorial series explains how to create own Kibana plugins. This first part
> explains the basics.
Apart from that, take a look at my github ([https://github.com/JuanCarniglia](https://github.com/JuanCarniglia)) perhaps you can get an example or two from there.

Hi guys,
Something new about this topic?
It's always not possible to make something like this in scripted field ?
```
(sum of disk usage) / (sum of disk size).
```
Thanks !
Have a nice day.

This plugin [https://github.com/ommsolutions/kibana\_ext\_metrics\_vis](https://github.com/ommsolutions/kibana_ext_metrics_vis) allows you to to such things.
