    Calculated item based on an existing item

    Hello everyone!

    I am using Zabbix 2.4, and I am trying to create a calculated item based on another item. This is all done in the Items and Graphs prototypes for a Discovery rule in a template.

    The existing item is as follows:

Name:	sourceitem.png
Views:	1
Size:	14.2 KB
ID:	317564

    I want to create something like this:

    Click image for larger version

Name:	destitem.png
Views:	1
Size:	18.0 KB
ID:	317565

    The problem is, I can't re-use the key since it's being used for the first item, and as such Zabbix will fail when adding it, and I write anything else, I get no data.

    Suggestions?

    If it helps, I want an easy way to visualize the amount of free space; I have tried the built in keys but were giving me false data so I used this template instead (Powershell based), that reads directly from the Windows performance counters. It contains Free Disk Space metrics in both a percentage and a total Megabytes fashion.

    I will also take suggestions on how to get the graphs that I want, in a different way. It doesn't need to be with those keys, but I discovered that pie charts are quite good for what I want.

    Thank you very much! Cheers!
