Calculated item on template to sum up LLD Item prototype values of the same host.

[verde]

Hi, how to tweak a calculated item formula to achieve the following? I have a template that includes LLD item prototypes currently working on Zabbix 6.2.6.
On the hosts using the template I would like to sum values from their own LLD item prototypes, so I created a new calculated item as part of the template (not prototype), but it's not working yet.

I've changed the formula with small variations but none worked. Thanks

Template calculated item. Formulas tried:

sum(last_foreach(//prefixKey[*]))

sum(last_foreach(/{HOST.HOST}/prefixKey[*]))

Item prototype:

Discovery rule macros: {#ITEMVAR} {#ITEMNUM}

Nobody gave insights, but I figured it out.
It's not documented but the calculated formula should follow the same "format" as the key being looked for. On my case, the LLD Key is "prefixKey[{#ITEMVAR},{#ITEMNUM}]", so the calculated formula that worked was: " sum( last_foreach(//prefixKey[*,*]) ) "

Thanks for posting this. Helped me with something similar without having to go through the zabbix documentation

Cheers!

For Zabbix 7

item prototype: (Numeric): net.if.criticality.error.[{#SNMPINDEX}]


Item: sum(last_foreach(//net.if.criticality.error.[*]))
