memory usage and hobbit

I have been using Hobbit for awhile, but I still have all my old bb19
clients installed and reporting to the Hobbit server.  I need to monitor
memory for a new system so I thought I would try the Hobbit client this time
around.  The package is listed as this:
 
 hobbit-client_4.1.2p1-1_sparc.deb 

Why does the Sparc package have a .deb file extension?  How can I had a
Debian package to a Solaris system?  Is there another way to monitor memory
on a system without using the new Hobbit client?

Thanks
