You're better off using the Log Insight agent built into the vROps appliance as you can select which port and protocol to use to send logs. Using the Content Pack for vROps will give you the filters and parsers necessary to grab all log files, otherwise you can declare them yourself. The config file is at /etc/liagent.ini.
I've been looking at this further and cannot see how to do this? Are there any articles to follow?
I've found this: Log Forwarding
But this is for 6.7 and I cannot see Administration > Management > Log Forwarding in the 6.6.1 UI.
