SNMP Discovery Rule doesnt work

[Enycon]

Hello,

this is my first post here - sorry for my bad english or any other mistakes!

Im currently trying to monitor all Site2Site-VPNs on our Barracuda Firewall and im using the Template "Template Barracuda NG Firewall SNMP" to achive that.

This template uses a discovery rule with the SNMP OID "discovery[{#SNMPVALUE},PHION-MIB::vpnName]":



Testing this gives me the following output (This is only a part, there are actually around 350 elements):
[{"{#SNMPINDEX}":""FW2FW-CC"","{#SNMPVALUE}":"FW2FW-CC"},{"{#SNMPINDEX}":""IPSEC-v2-Deutz_10.151.29.0-24-185.247.243.128-25{38195}"","{#SNMPVALUE}":"IPSEC-v2-Deutz_10.151.29.0-24-185.247.243.128-25{38195}"}]

There is a filter on this rule: {#SNMPINDEX} matches @BarracudaNGvpnExcl // @BarracudaNGvpnExcl Character string included ^.*$





The only item prototyp:



Other discovery rules on this host are working fine with a more or less similar layout.

Does anyone have an idea what Im doing wrong here?
Could it be, that zabbix is having trouble interpreting the "{" and "}" within the return value?

Thank you in advance!

Best regards,
Enycon

Okay! After a solid 8 hours or troubleshooting, I decided to disable the filter once and it actually fixed it...
