Splunk Add-on for NetFlow: Why are there no src_inf or dst_inf fields in transforms.conf? How do I capture the interface name?

Hi Guys,

I have installed the Splunk Add-on for NetFlow and also checked transforms.conf, fields but I can't see about src_inf or dst_inf values e.g: interface name Ethernet 0/0... How do I capture interface name? Thank you so much.

if it's in the flow data, you can just use Splunk's field extractor to do what you want. http://docs.splunk.com/Documentation/Splunk/6.3.1/Knowledge/ExtractfieldsinteractivelywithIFX

Hello, I have two questions about your post:

1) What are these flows coming from (Cisco router, VMware NSX, nProbe)?

2) Is NetFlow or IPFIX being exported?

Thanks.
