[Trigger]Make an estimation for HDD data

[fangames]

Hello all,

(Sorry if i have a wrong langage, i dislike google translate )
I would like to make a new trigger in my Windows Template.

In discovery mode, i have vfs.fs.size[{#FSNAME},free] available. Then i make a new item in calculated with this command :

last("vfs.fs.size[{#FSNAME},free]") / (last("vfs.fs.size[{#FSNAME},free]",90d) - last("vfs.fs.size[{#FSNAME},free]"))

But this command return "Error division by 0 impossible".

I try only this command in my item for compare : last("vfs.fs.size[{#FSNAME},free]",90d)
It return 13,512 GB

I try this now : last("vfs.fs.size[{#FSNAME},free]")
It return 13,512 GB.

Now i understand the problem, last(90d) and last() return the same value.

My question : How can i get the value for HDD State 90 days ago. (In my graphics i have ~28GB, and today 13,512GB)

Thanks for your help. (I will try min() tomorrow but, if anyone have already make it or are better on Zabbix than me ^^)

Hello and welcome to Zabbix forums!

I did not test it myself but you can try your trigger with last(,90d)

https://www.zabbix.com/documentation/2.4/manual/appendix/triggers/functions

And then in the calculated formula:
last("vfs.fs.size[{#FSNAME},free]") / (last("vfs.fs.size[{#FSNAME},free]",,90d) - last("vfs.fs.size[{#FSNAME},free]"))

Hope this helps!

Best Regards,
Ingus

Just for acquaint

Thanks you for your help, i have add this, and will edit this post monday for the result.

(Since my 1st message, the min() return the min value on this period, then it's not what i want)
