ip address and hostname from fowarder

I am using a host segment to set a 'hostname' (we have multiple hosts on one box) as set out below:

[monitor://c:\logs\node-21\*.log]
host_segment = 2
index = node_logs
sourcetype = node_logs

I would like to see my other 'hostname' and the ip address. The reason being I may need to move these 'hosts' between machines so it would be good to know the ip address they came from.

Has anyone got this kind of setup or have any good ideas?

Regards Andy
