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
