last(/Workstation/system.sw.os[name],#1)<>last(/Workstation/system.sw.os[name],#2)

tx from your reply, if i have 10 item i have to add 10 times ?
and im not familar which the string, if template name was TEMPLATE and item ITEM, can you update em how fill this string ?

last(/Workstation/system.sw.os[name],#1)<>

Workstation is the name of my test VM, so you can replace it with your template name.
This expression just compares the new value and the last value, it means that for the next checking time the problem should be resolved because the new and the last value will be equals. Probably the best way is to create a template, for example, "Check OS name and version", with macros {$OSNAME} = Your_OS and create item system.sw.os[name] and trigger last(/Check OS name and version/system.sw.os[name],#1)<>{$OSNAME} there.

I probably did not explain the problem correctly. i dont want to check version , need to compare 10 items if they have same value its OK, If one of the items is different, issue a warning. Because all items must have the same value.
also zabbix-agent on hosts send value to zabbix server.
