Item that calculates sum of last values ​​equal to 0?

[cesarsj]

Is it possible to create a calculated item that calculates the sum of the last collected value of several items equal to zero? This is why our backup checks on a server return the exit code, and zero is successful. I would like an item to sum and alert if the total was less than the total backups.

You only need it to the trigger? If it's you just need to sum all itens and check if the sum is greater than 0
{template:key1+template:key2+...+template:key3}>0

You value can be 0/1 only? And can you revert your items to be 1 not 0? If not then it will not be easy to do.

No, because I want the values equal to the exit code: https://lxadm.com/Rsync_exit_codes . Example: Backups with latest values 0 = 44. Less than 44 triggers the trigger
