Do you mean one graph showing the individual (e.g. load average) utilisation 
for 25 servers? It seems (at least for me on 4.2.3) that the metrics report 
only works up to 2 servers, but the method from before the metrics report, 
adding more host names to the normal trends graphs, works fine at least up to 8 
servers.

So, view the "cpu" page for a server, click on the graph, you should be at a 
URL such as:

http://xymon.mydomain.com/xymon-
cgi/hobbitgraph.sh?host=server1.mydomain.com&service=la&graph_width=576&graph_height=120&disp=zcs-
mbs1.zmb.com&nostale&action=menu

Now, edit the URL in your browser, to something like this:

http://xymon.mydomain.com/xymon-
cgi/hobbitgraph.sh?host=server1.mydomain.com,server2.mydomain.com&service=la&graph_width=576&graph_height=120&disp=zcs-
mbs1.zmb.com&nostale&action=menu

Keep adding host names as used in Xymon to the host= parameter, separated by 
commas.

You may want to keep this URL, by bookmark, or by making a small web page that 
loads the IMG urls (e.g. http://xymon.mydomain.com/xymon-
cgi/hobbitgraph.sh?host=server1.mydomain.com,server2.mydomain.com&service=la&graph_height=120&graph_width=576&color=green&nostale&action=view&graph=hourly)

It would be nice to have at tool to set up such views, but I think the better 
investment would be building a new web interface with a real framework which 
would make things like this easier to write ...
