[Xymon] linux xymon-client memory labels

I test many client machines.  For Windows clients I use the Powershell client, and for Linux I use the 'xymon-client' that comes from the distro package sources.  I've noticed that the Memory readings displayed on the server's webpage are flip-flopped for Windows and Linux.  Windows client Ram stick usage is called 'Real/Physical', but Linux client Ram stick usage is called 'Actual/Virtual'.  Can anyone tell me where/what in the linux xymon-client to flip so the results sent to the server will be displayed the same as Windows?  It would be nice if the Ram readings from both Win and Linux had consistent names.

Thanks, Kris Springer
