That gets you the status page which is what the server creates after
it's processed the client message it receives.

You can get the client section directly doing:

# /usr/local/xymon/server/bin/xymon 127.0.0.1 "clientlog hostname.domain.com section=memory"
[memory]
memory    Total    Used
physical: 2047 1020
virtual: 2046 890
page: 3948 1731
