{ITEM.LASTVALUE} - Not working as expected?

[shlomia]

Hi, So I'm trying to get in my action message the new value and the last value of the problematic item.
Zabbix version: 5.0

So I configured my message as:

Old Value: {ITEM.LASTVALUE}
New Value: {ITEM.VALUE}

and when the value changing on item, I expect to get:

Old Value: Value before the problem occured
New Value: Value after the problem occured

But I get the new value for both which is {ITEM.VALUE}.

What is going on?

None of this macros will give you "Value before the problem occurred".
For that you must use function last(#2) in trigger expression.

But how do I use it in my 'action' message notification? Any chance for an example please? :P
