I need to monitor a VPN Tunnel, I already have the "Discovery Rule" configured and communicating with the Firewall correctly.
However, I am facing problems configuring the "Item Prototype", to then create Trigger Prototypes, to generate the Tunnel drop alert.
It is returning some errors to me, with the settings I have made.
When configuring the "SNMP OID" field with "discovery[{#SNMPVALUE},.1.3.6.1.4.1.12356.101.12.2.2.1.3]" it returns the error below
"Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "[{"{#SNMPINDEX}":"1.1","{#SNMPVALUE}":"...

Below is the configuration image

Configuring the SNMP OID with "1.3.6.1.4.1.12356.101.12.2.2.1.20.{#SNMPVALUE }" or "1.3.6.1.4.1.12356.101.12.2.2.1.20.{#SNMPVALUE }" it returns the error below
