Receive syslog from collector

[ssafronov]

I've got multiply networks and a server, that collects syslog messages from different hosts (switches, routers, linux and windows machines).
After that, syslog is transferred to syslog anallyser (other vendor).
When i tried to add nagios LS to receivers, i started collect messages too, but i see a collectors IP address as a source (not a real switch or linux machine).
How can i translate source IP via rsyslogd to nagios?
Thank you!

Does the forwarder include the original IP address? If so, it can be parsed out with additional filters. We would need sample logs to create a filter, but I would strongly encourage anyone to try setting up the filters themselves after reviewing https://support.nagios.com/kb/article/n ... ew-98.html. The "Logstash Example Configuration" section specifically steps through setting up custom filters.
