Last and prev value for trigger

[bforpc]

Hello,

i have this trigger every minute running;

last(/workerproc/proc.num[{$PROC_NAME2},,,{$PROC_CMD2}])<>1

sometimes, the last value is 0 but it is not a failure. Only if the last and prev values are 0, then the trigger should release.
So ist should be a expression with an "and" statement of the two values.

last(/host/item,#1)=0 AND last(/host/item,#2)=0

Which part you did not find? This one?
https://www.zabbix.com/documentation...ctions/history

last (/host/key,<#num<:time shift>>)
The most recent value.	See common parameters. #num (optional) - the Nth most recent value

Of course, if you know where the needle is in the haystack. Tons of documentation, some from zabbix itself, which describe a completely different approach, or on the Internet, which are completely out of date.
So be it. With the help above I was able to solve the problem.
So thank you.
