I am struggling with something which should be basic in my mind.
I am trying to create an Item Prototype that sums the sent and received bits/sec on a port using Zabbix 6.4.
This is what I have filled out:
Name: Calculated Port throughput
Key: net.if.bandwidth[{#IFNAME}]
formula: net.if.in(ifHCInOctets.{#SNMPINDEX})+ net.if.in(ifHCOutOctets.{#SNMPINDEX})
Why am I getting a “Incorrect value for field “Formula”: incorrect expression starting from “net.if.in(ifHCInOctets.{#SNMPINDEX})+ net.if.in(ifHCOutOctets.{#SNMPINDEX})” message?
