SNMP Calculated item and discovery rule

[Thibault]

Hello !

I try to create a calculated item prototype based on two SNMP items prototype:

• ifOutOctets[{#SNMPVALUE}] => OID:IF-MIB::ifOutOctets.{#SNMPINDEX}
• ifInOctets[{#SNMPVALUE}] => OID:IF-MIB::ifInOctets.{#SNMPINDEX}

My calctulated item is :

• Key => ifTotalOctets_calc[{#SNMPVALUE}]
• Formula => last("ifOutOctets[{#SNMPVALUE}]")+last("ifOutOctets[{#SNMPVALUE}]")

When i save it, Zabbix say "Item Created" but the problem is that their is no new items created on host!

I also try the same calculated item prototype with Zabbix agent keys and it works.

Can anyone tell me why it doesn't works and if there is a way to fix it ?

Thanks !

Works for me:

last("hrStorageSize[\"{#SNMPVALUE}\"]")-last("hrStorageUsed[\"{#SNMPVALUE}\"]")

[*]Formula => last("ifOutOctets[{#SNMPVALUE}]")+last("ifOutOctets[{#SNMPVALUE}]")[/LIST]

First of all - Are you mistyped in Formula OR you use ifOUTOctets twice for specific reason?

Then, to calculate the Total traffic, you have to create three(3) Items
1) ifInOctets.[{#SNMPINDEX}] -> OID:IF-MIB::ifInOctets.{#SNMPINDEX}
2) ifOutOctets.[{#SNMPINDEX}] -> OID:IF-MIB::ifInOctets.{#SNMPINDEX}
3) ifTotalOctets.[{#SNMPINDEX}] -> last("ifInOctets[{#SNMPVALUE}]")+last("ifOutOctets[{#SNMPVALUE}]")

Also you can create three prototypes in LLD rule (in, out, total) and then all total Items will be created automatically after LLD will done.

I attached my own prototype for Total traffic on interface.
