Hi Gabor,

We want to use snmpv2v/snmpv3 only going forward. This is the reason I want to add the field "agent-addr". Is there a way to add "agent-addr" field with snmpv2c/snmpv3 ?

Regards,
Shivani Maurya

Thanks Shivani for the example!

I didn't know "agent-addr" is a standardized SNMPv1 trap element.
I've found it in the SNMPv1 RFC too. [1]

Unfortunately, syslog-ng only supports snmpv2c and snmpv3 versions.
I've checked the code of snmp-dest() and I think it would be _relatively_ easy to add snmpv1 support.
I can open a feature request on GitHub, as I'm not sure when we could get to this in the near future, or is there any reason against SNMPv1.

Regards,
Gabor

As I said, I think you can achieve this using `snmp-obj()`.
Try the following:

    snmp-obj('.1.3.6.1.6.3.18.1.3.0', 'Ipaddress', "${SOURCEIP}")
