Does anyone know if ARD has its own log? Can I enable an ARD log?

I don't see an ARD client log on my Macs, so I have no way to accurately track down successful and/or failed ARD connections.

defaults, ps, netstat, etc are all handy for determining if ARD client is actually running and and for seeing current connections, as well s configuring the client itself, but Id like to see a log of all ARD auth attempts on ports 5900, 3283, etc. Logs such as the system.log, the authd.log, etc don't show any ARD connectivity stats.
