Zabbix 6: Previous Value in message template

[Alexander Javoronkov]

Hi, fellow zabbix masterminds,

In Zabbix 5 I've had the following message template showing the change of a value:

Value: {{HOSTNAME}:{ITEM.KEY}.prev()} → {{HOSTNAME}:{ITEM.KEY}.last()}

However, this was deprecated with the release of Zabbix 6: https://www.zabbix.com/documentation...ression-macros

Now that I've created a fresh Zabbix 6 installation (6.2.1-1), I'm struggling with the notification messages. The documentation is pretty confusing: https://www.zabbix.com/documentation...eration/macros

Example 2 -- Processor load is: last(/zabbix.zabbix.com/system.cpu.load[,avg1] -- yields just the same text.

Example 3 -- Latest value: last(/{HOST.HOST}/{ITEM.KEY}) -- shows the text with the {} stuff replaced with the hostname and the key, like this: Latest value: last(/virtualtest.001.nmi.ru/trapperitem1)

I've had a bit of luck with the new "{?" syntax: when I manually type the item key, I see that it works like intended:

Value1: {?last(//trapperitem1,#1)}
Value2: {?last(//trapperitem1,#2)}
Value1: 114
Value2: 0

However, when I try to use the {} placeholders for the item key -- no dice:

ITEM.KEY=[{ITEM.KEY}]
Value1: {?last(//{ITEM.KEY},#1)}
Value2: {?last(//{ITEM.KEY},#2)}

ITEM.KEY=[trapperitem1]
Value1: *UNKNOWN*
Value2: *UNKNOWN*

What am I missing?

P.S. I would really like to use something like the "previous value of {EVENT.OPDATA}" instead of the "last" that works for the first trigger item only, but I can't find it in the docs.

This works in v6.2.3 - prints previous value (e.g. in an Action message):

{?last(/{HOST.HOST}/{ITEM.KEY1},#2)}

This works in v6.2.3 - prints previous value (e.g. in an Action message):

{?last(/{HOST.HOST}/{ITEM.KEY1},#2)}

Unfortunately I am unable to get it to work.

The path where the message is:
Administration / Media types / Telegram / Message templates / Problem

My action message is:

Test=[{?last(/{HOST.HOST}/{ITEM.KEY1},#2)}]

Zabbix 5 says:

Test=[{?last(/realhostname.001.gpucloud.ru/memory.pused,#2)}]

Zabbix 6 says:

Test=[*UNKNOWN*]

I have some success after the zabbix-server upgrade:

Zabbix server: Version has changed (new version: 6.2.3) / 3s
→ 6.2.3
Test=[6.2.2]

The previous test (shutting down the zabbix-agents) is working now as well:
Test=[0]

Is the difference between 6.2.2 and 6.2.3 that drastic? Hmm…
