Problem with sum two items

[pawel]

Hello,

I'm trying to sum two items with last().

In my formula i have :

last("vfs.fs.size[../media/data1,total]")+last("vfs.fs.size[../media/ssd1,total]")

but what I receive is only first item.

What should I change to receive sum of both items?

Regards, Pawel

The expression is correct. Do you have both of the items and they are receiving values with the same parameters ?

Yes, I have both items and receive values in GB.

I bet that there might be the typo, try to copy this and just change the keys:

last("vfs.fs.size[/,total]")+last("vfs.fs.size[/boot,total]")

I've spotted that you have there an item key starting with ../ , are you sure that those are correct ?

Regards,
Alex!
