Firstly, it would be best practice to raise this in the correct location of the forum, this is the Mobile Admin section rather than Kiwi Syslog.
Next would be recommending to raise this with SolarWinds Support directly if you have a question like this, however raising this in the forum and with support at the same time might deem more beneficial for you for future circumstances.
What are you trying to achieve? Are you asking how one adds a system to log the events within Kiwi Syslog?
Depending on what you are trying to achieve will determine whether you want to forward the logs from the Orion Suite to Kiwi Syslog, it may be a waste of time if you aren't going to use it, after all you could just monitor the Orion Suite from its own dashboard rather than going to the effort of forwarding logs to a smaller system like Kiwi Syslog.
