Aggregate calculated item syntax

[alexlh]

Hi,

I'm confused about which syntax to use for aggregated calculated items.

I have a working calculated item that uses the syntax:

Key: junos.rpm.probe.NETARCH.loss.[{#SNMPINDEX}]
Formula: (1 - last("junos.rpm.probe.NETARCH.ProbeResponses.[{#SNMPINDEX}]") / last("junos.rpm.probe.NETARCH.ProbesSent.[{#SNMPINDEX}]")) * 100

And this works.

I'm trying to create another item which would add up all junos.rpm.probe.NETARCH.loss.[*] in a single item.

This seems to describe a different syntax than the one I used above:

https://www.zabbix.com/documentation/5.4/en/manual/config/items/itemtypes/calculated/aggregate

So when I use this:

Formula: sum("junos.rpm.probe.NETARCH.loss.[*]")

I get the error:

Cannot evaluate function "sum()": item "cr01-cnco01.tingfiber.net:junos.rpm.probe.NETARCH.loss.[*]" does not exist.


While I do have items like these on the host:

• junos.rpm.probe.NETARCH.loss.[""XXXX""]
• junos.rpm.probe.NETARCH.loss.[""YYYY""]

Does anyone have a pointer about what I'm doing wrong?
