Hello Keith,
While the LEM is a linux based server, it's a sealed appliance from your side so you wouldn't be able to use the LEM to set this up. If you haven't seen it already, it looks like this is what they want you to set up:

It looks like you might be able to send the messages via syslog, but I don't see a connector for it, so you would need a connector request if you wanted LEM to process the data.
