Trigger to check size differences between 2 files

[Beef76]

Hi all,
i started to use zabbix one week ago so i'm new on it.

I want to check size differences between two files.
I mean ,i have backup files which are saved every day.

And i want to check if the size of the file have brutally changed between the two saves ( more than 15%)

So i created a trigger which check the size of file, but i can't find the way to make the trigger working as i want.

I have an idea but i don't know if it's possible to do it.

I want to do (last size check)-(previous size check)<( previous size check)*(15/100)

But i don't know if it's good and if it's possible to do it.

is someone can help me ?

Create calculated item
(last size check)/(previous size check)-1
and trigger if value item >0.15 and nodata(300)#1

i 've got Zabbix 1.6.4 and there is no calculated item type for this version

It's one file in two state of size?
You create one item sizecheck - size of file.
When zabbix check this item (previous size check) = last(#2) and (last size check) = last(#1) (or last(0))
Create trigger: {hostname:sizecheck.last(#1)}/{hostname:sizecheck.last(#2)} > 1,15 & {hostname:sizecheck.nodata(600)}#1 if you check once of day

Thanks a lot, it works fine

I just added a OR with {hostname:sizecheck.last(#1)}/{hostname:sizecheck.last(#2)} > 0.75

But that was just i wanted to have
